DESKTOP PASSIVE MONITORING SYSTEM

Heritage Audio’s Baby RAM is the ultimate passive-monitoring system, delivering the most transparent signal with the best stereo imaging of any other passive designs available!

Classic console design meets a passive signal path.

Introducing the Baby RAM: a boutique, passive-circuit monitor controller inspired by classic European console designs. Baby RAM is the ultimate controller for total transparency — a zero-compromise signal path, paired with a simplified control set keeps both your monitors and your ears where you need them.

Baby RAM features a 4 gang, 24 step rotary switch for volume as opposed to cheaper stereo potentiometers, which means the precision of your stereo signal is perfect on every position! Baby RAM also has no insertion loss, meaning that there’s no extra coloration or signal loss at any settings.

Complex design with simplified workflow.

Baby RAM might pack a zero-compromise circuit design, but it couldn’t be any easier to use: 2 stereo -pair inputs and outputs — both balanced and ground free (unbalanced compatible) on gold plated TRS jacks, and Mute, Dim, Mono, and Volume monitoring controls make Baby RAM a breeze to work with. And with it’s passive design, it also means you have no concerns with bad power supplies, as no supply is needed!

Baby RAM is built with the most cutting edge methods in manufacturing and design, without ever compromising audio quality or cutting corners — all at the Heritage headquarters in Spain.

THIS IS WHERE BABY RAM WILL TAKE YOU

The OST-4 is a 500 Series enclosure in a “square box” format, able to accommodate up to 4 modules. As the rest of the new Heritage Audio line of 500 Series enclosures, it features “ON SLOT” Technology (OTS).

“ON SLOT TECHNOLOGY” takes advantage of last generation power electronics to handle power supply on a “per slot” basis. Each slot has its own power supply linear regulation stages; therefore modules are isolated from the rest. They just share the metal enclosure.

With literally hundreds of brands making 500 series modules, we at Heritage Audio think this is the professional way of handling this reliably, eliminating issues often associated with sharing power between different modules of different brands and natures.

Each slot features test LEDs for checking correct power operation (red for +16v, green for -16v), located aside of the slot connector.

Thanks to the use of OST, the power capability of the OST-10 is 400mA per rail per slot maximum, with an overall of 700mA per rail, whichever is reached first. Each slot has its own red (+16v) and green (-16v) LEDs for easy testing of the power status.

Phantom power available is 80mA total.

The RAF Blue Gray enclosure is made out of heavy gauge steel.

Connections are by means of gold plated XLR Input and Outputs.

SPECIFICATIONS

• On Slot Technology

• Maximum audio rails current: 700mA per rail, or 400mA per rail per slot, whatever is reached first.

• Maximum phantom power current: 70mA.

No ´73 equalizer will present the correct equalization curves without high quality capacitors and, most importantly, correct “Vinkor” type pot core inductors. More than often this type of products has these expensive inductors replaced with generic ferrite core ones or, even worst, the mid band dual inductor replaced with a single one. Never in Heritage Audio products!!, as the impact of replacing these to the eq curves is dramatic, leading to incorrect curve´s shapes and high frequency phase distortion which in no way honor the design.

The HA73EQX2 Elite employs WIMA 5% capacitors in the EQ section as well as 3 correct vintage type “Vinkor“pot core inductors so the eq curves are virtually undistinguishable from the handmade equalizers in the HA line. Customers can expect the same sonic quality and feel they have come to appreciate from Heritage Audio.

The HA73EQX2’s preamp section features gain, output trim, -20db pad, polarity reverse, a high pass filter, and +48v phantom power.  The HA73EQX2’s EQ section features a high shelving EQ, midrange EQ, low shelving EQ, a variable high pass filter, and EQ Bypass.  The HA73EQX2 comes housed in a rugged 1RU British steel and aluminum chassis and utilizes an external power supply for low noise operation.

Our Elite Series pledge to always deliver the best value for your investment, with zero compromises, Western European made high-quality gear to enhance your musical experience.

El compresor de válvulas Heritage Audio HERCHILD 670 es un compresor de válvulas limpio y de diseño inteligente que ofrece un sonido legendario finalmente disponible para todos.

Después de décadas de ser tan raro, difícil de conseguir y casi considerado místico y prácticamente imposible de adquirir, la mayoría de las personas simplemente asumieron que nunca podrían usar esta leyenda, pero no se preocupen, el modelo 670 de HERCHILD finalmente está aquí para todos.

Durante años, la industria se ha referido a esta bestia a válvulas como algo especial, único e incluso mágico. El Fairchild original ha sido, sin duda, una parte esencial del sonido de tantos éxitos durante varias décadas... Sin duda, se ha ganado el título de "abuelo" de todos los compresores. Al estar basado en 22 válvulas y 9 transformadores, puedes estar seguro de que el HERCHILD Modelo 670 imprimirá su sonido característico en todas tus pistas, proporcionando ese tono familiar que todos adoran. Aunque fue diseñado originalmente para ser utilizado para cortar masters de laca para álbumes de vinilo, los ingenieros no tardaron en darse cuenta de que podía hacer mucho más. Pronto se convirtió en una herramienta de estudio esencial para muchos artistas, ingenieros y productores innovadores y se podía encontrar en la mayoría de los estudios profesionales.

Como solo se fabricaron entre 500 y 1000 unidades originalmente, simplemente no hay suficientes para todos. Además, el original requiere un mantenimiento especial considerable y, después de casi 60 años, simplemente no quedan muchas en buen estado. Ahí es donde entra Heritage Audio...

Heritage Audio ha logrado seguir con éxito el diseño original y rastrear los componentes necesarios para ofrecer una alternativa moderna. Le ha llevado años a Heritage Audio, pero siente que finalmente ha producido algo tan especial que es capaz de permitir que el viejo abuelo se tome un merecido descanso y dar paso a la nueva sangre. Manteniéndose fiel al original en términos de respuesta y sonido, Heritage Audio ha podido agregar algunas cosas para hacerlo más práctico en los estudios modernos. En primer lugar, Heritage Audio ha brindado acceso directo al control de pendiente continuamente variable. Esto es algo que hace que el compresor sea mucho más flexible y solo estaba disponible en el original a través de un incómodo ajuste de tornillo oculto al acceso inmediato. Luego está el filtro SC. Hoy en día, es casi imposible concebir un compresor sin esta función, ya que se ha vuelto tan importante en el uso diario. Aquí Heritage Audio proporcionó 4 frecuencias diferentes para elegir para adaptar con precisión sus necesidades de compresión. Heritage Audio también reprodujo fielmente los tiempos de ataque y liberación en la sección de constante de tiempo para que puedas recrear con confianza la sensación de su predecesor. El modelo 670 de HERCHILD es una unidad de dos canales, por lo que puedes usarlos de forma independiente o en conjunto. Dispone de cuatro modos de funcionamiento: individual, enlace (estéreo), LAT/VERT (MID/SIDE) y enlace LAT/VERT. El modo LAT/VERT ofrece un nuevo abanico de opciones para tu mezcla.

Finalmente, después de tantos años de estar inalcanzable para los mortales, el HERCHILD Modelo 670 ya está aquí, al alcance de todos. Disfruta del sonido que ha bendecido miles y miles de éxitos a lo largo de los años. Siente la calidez que envuelve tus pistas y las distingue con orgullo del resto.

AJUSTES DE UMBRAL DE CC

El modelo 670 de HERCHILD, al igual que el original, utiliza una curva de relación que se desarrolla progresivamente, por lo que no es posible describir la relación como 2:1, 10:1 o algo tan exacto.

FILTRO SC

Este es un filtro de cadena lateral que se aplica únicamente a la señal de control para determinar si el modelo 670 de HERCHILD será menos sensible a ciertas frecuencias y en qué casos. Hay 5 opciones disponibles: 50, 100, 200, 350 Hz y desactivado.

CARACTERÍSTICAS:

• Filtro de cadena lateral de compresión totalmente basado en tubos para las necesidades actuales
• El acceso inmediato al modo de pendiente continuamente variable LAT/VERT hace posible el procesamiento MID/SIDE
• Diseño limpio e inteligente para garantizar muchos años de uso.
• Ese sonido legendario finalmente disponible para todos
• 4 modos de funcionamiento: individual, enlace (estéreo), LAT/VERT (MID/SIDE) y enlace LAT/VERT
• Configuración de constantes de tiempo

• Salidas de línea (x2): Conector XLR macho chapado en oro
• Válvulas: (22) Válvulas intercambiables por el usuario con fácil acceso
• Entrada de alimentación: conector de entrada de alimentación estándar IEC
• Selector de voltaje: Aquí puede seleccionar la entrada de voltaje correcta según el país en el que se encuentre

Occasionally, something so special arrives, it turns the music industry Upside down (and inside out). That is why Heritage Audio is incredibly pleased to offer the world’s  first reproduction (and a dead on one at that) of the “Holy Grail” of classic EQ’s. The “MOTORCITY EQualizer”.

Recreated from  Motown units owned by Eight-time Grammy winning producer, mixdown artist, and innovative engineering genius Michael Brauer, Heritage Audio has left no stone unturned, recreating the unmistakably huge, punchy, and warm signature sound that makes this EQ as classic as the hits it helped create. From the 10-gauge hand brushed aluminum face plate, historically accurate control layout including custom molded bakelite knobs, the MOTORCITY Equalizer looks the part. More importantly, the unique passive equalization circuit is identical and fully faithful to the original design. The MOTORCITY EQualizer is so precise, it stands as the only EQ available that can rival, or even “best” the popular Pultec EQ.

It was no simple task to make a 100% accurate reincarnation. Peter Rodriguez and his team from Heritage Audio worked for weeks with their friends at Black Lion Audio. Seth Berman from Black Lion Audio’s NY facility took the lead in getting the info together for Heritage to work their magic. Everything was complicated by the 2020 summer lockdowns in Europe and the US, but they got it done! The exceptionally tight mil-spec 1960’S tone capacitors and inductors are simply no longer available. Replace with a alternate? Not on your life. Heritage Audio had custom recreations built from scratch. Each with exact materials, values, and tolerances:  A perfect interchangeable clone of the very few originals remaining. Just add 60 years of dust, and you’ve got twins

The MOTORCITY EQualizer is a completely analog, passive EQ design with seven accessible frequency points across the tonal spectrum. Each frequency has a stepped rotary switch capable of a flat response, or up or down up  8db in 1dB increments. Frequency points graduate from 50hz, 130hz, 320hz and 800hz before jumping to 2000hz, 5000hz, peaking at 12,500hz. The front panel also features a simple in/out/off toggle switch with top hat knob and jewel light power indicator. All rotary switches have easy to read from a distance “General Radio” bakelite style knobs recreated to look exactly like the originals (remember, this is not a slider-style graphic EQ). Finally, it features a master gain control (-8db/+8db) , again in 1dB increments. The incredibly simple 1960’s accurate back panel features a power supply jack, and an XLR input and output. The sound itself is exactly what you’d expect. It packs a punch without sounding harsh or distorted. While something as simple as an analog seven band EQ might sound more like hype than hyper goodness, hearing is believing. Why has Heritage audio gone through the seemingly impossible task of bringing them back to life? Michael Brauer will tell you this: It simply got that sound! The Heritage audio MOTORCITY EQ is not a digital equivalent, not a respectfully close replica and not a more compatible modernized “improvement.” The MOTORCITY EQualizer is nothing more or less than the genuine article finally made available for the general public.. For the very first time in history, you can integrate this true spec to spec carbon copy of both form and function into your own studio.

BRITISH-SPEC CHANNEL STRIP WITH DIODE BRIDGE COMPRESSOR

50 YEARS OF ANALOG DESIGN IN ONE RACK SPACE.

Introducing the Heritage Audio BritStrip — the culmination of 50 years of analog design in a single rack unit. Britstrip nails the sound of yesterday’s iconic recordings for today’s demanding engineers.

The BritStrip combines a real-deal 73 mic preamplifier, an expanded 73 equalizer, a discrete Class-A DI, and the infamous diode bridge compressor from the Heritage Audio Successor. The closest equivalent of the BritStrip would be chaining together a 73JR, 73EQJR and mono Successor — a $3000 value pack in itself, with added routing flexibility.

THE MIC PREAMP THAT MEETS ALL THE DEMANDS.

The BritStrip starts with the same preamp as our 73JR, with a new custom input transformer co-designed with Carnhill and exclusively made for HA in the St Ives factory.. The preamp also features a custom Carnhill St Ives output transformer, which completes it’s all discrete, Class-A, 3-gain stage design. The preamp features 80 dB of gain, 20dB pad, phase reversal and an impedance switch for 1200 or 300 ohm input.

THE DISCRETE CLASS-A DI

The DI is also taken from the highly acclaimed design found in the Heritage Audio 73JR, an all-discrete Class-A JFET circuit in front of the microphone transformer, giving you all of the color and weight you could ask for.

The DI also includes a passive thru output to feed a separate amplifier.

 AN EXPANDED 73 EQUALIZER.

The BritStrip eq features 3 Vinkor pot core inductors in the mid band and high pass filter sections. The impact is hard to believe with extreme boosts being exceptionally musical.

The mid band is great for sculpting fat and punchy snare, kick, guitars, vocals — you name it! No need to be subtle like you would with most eqs — BritStrip doesn’t sound phasey or loses headroom in extreme settings.

The inductor-based low-pass filter, directly taken from the 73 design, lets you control out of range low end — without affecting the quality of your desired frequencies.

The high and low shelves have been extended to include a bell mode — making them more versatile than ever before.

A SUCCESSOR-LIKE COMPRESSOR

The diode bridge bus compressor needs little introduction, as it’s the same compressor found in the multi award-nominated Heritage Audio Successor. Diode bridge compression, a 60 year old patent, took on a whole new life with the expanded features and incredible fast attack/release times of the Successor.

With BritStrip, this powerful compressor design is perfect to use for tracking, thanks to it’s blend control and elaborate sidechain filter. This gives you plenty of tracking potential, as you can give instruments that “record-ready” dynamics as performers monitor — giving them a finished “real-time feel” as they perform.

The compressor section provides plenty of sidechain flexibility, with 5 frequency options, and an external sidechain input. And if that weren’t enough flexibility, 2 BritStrips can have their compressors linked for the ultimate stereo tracking solution.

ROUTING FLEXIBILITY

The BritStrip allows for compression and equalizer routing. Eq’ing pre-compression makes the compression detector more sensitive to the boosted frequencies and less sensitive to those cut. Inversely, eqing post compression makes the detector insensitive to the eq settings.

The OST-10 V2.0 500 series enclosure is designed for racking any and all 500-series modules and

devices, including ‘double wide’ modules and even the most demanding class-A and vacuum tube

designs.

The OST-10 V2.0 enclosure features Heritage Audio’s On Slot Technology, providing

maximum protection, filtering, and isolation to each channel. While most 500-series enclosures on the

market have a relatively simple power supply design essentially feeding every channel in parallel, each

channel of the OST-10 V2.0 enclosure has its own power supply, individually regulated and isolated from

the rest. This ensures that every 500-series module installed will perform at its peak potential, and that

no ‘ power hungry’ or even a faulty module will compromise the performance of another. In addition to

reducing interference, many 500-series devices actually exhibit lower self-noise and better performance

when racked in the OST-10 V2.0 enclosure, specially mic preamps.

A new and exciting feature in the V2.0 model is the Link feature, allowing each channel to be linked over

to the next at the push of a button (via back panel), no patch cables required!

As with all Heritage Audio products; the 500 Series OST-10 V2.0 enclosures are built utilizing the most

cutting edge methods in manufacturing and design, without ever compromising audio quality or cutting

corners — all at the Heritage Audio headquarters in Spain.

The 500 format is here to stay, be set up for it!

With the popularity of 500 Series modules showing no signs of waning, it makes more sense than ever

for both professional and home studios alike to have plenty of slots available to house their growing

collection of new and old 500 Series toys.

Don’t just house your 500 series modules, bring out the best in them!

While a 500 Series enclosure may not seem like the most exciting thing in the studio, you’ve got to have

them. It only makes sense to get one that is durable, not overpriced, compatible with any 500 Series

module you may have, and most importantly, one that will bring out the cleanest and very best

performance in your gear. With the OST-10 V2.0, you have a perfect solution for housing up to ten 500

Series modules in an enclosure which brings out the best of their sonic potential, in a portable, rugged

enclosure that won’t break the bank.

Safer, cleaner, more compatible!

Many experienced engineers are aware of certain ‘power hungry’ class A or vacuum tube based

modules which could cause banks of 500 Series modules to ‘brown out’ or not function, or that simply

would not work in some standard enclosures. The OST-10 V2.0 offers the widest range of compatibility

with all 500 Series modules, ensuring both that ‘demanding’ modules receive the power they need, and

that adjacent modules remain unaffected. Your 500 Series modules have simply never had it so good!

MASTER BUS STEREO ASYMPTOTIC EQUALIZER

70 YEARS AFTER ITS CREATION, THE BAXANDALL EQ GETS A DEFINITIVE UPDATE.

Baxandall equalizer’s topology, introduced to the public by Peter Baxandall in 1952, was a very ingenious way of obtaining high and low shelves with boost and cut option without using expensive rotary switches. This affordable circuit was soon adopted by hi-fi and console manufacturers for its simplicity, where parametric options aren’t needed.

Heritage Audio has successfully replaced the Baxandall topology with a functional equivalent — a much more musical one, implemented as a one rack space, master bus/ mastering type unit.

The Stereo Asymptotic Equalizer, affectionately known as Symph EQ, takes its name from the shape obtained by its shelf curves; where the boost or cut amplitude grows up until the asymptotic value is reached, keeping the ultra highs and sub lows always controlled.

Its sound can only be described as tight, sweet, and natural, and its use of parallel equalizing to obtain the desired response curves makes it to have exceptional low phase deviation and artifacts.

SHELVING WITH SURGICAL, BUT MUSICAL PRECISION.

A smart circuit layout allows for a maximum boost/cut of 10.5 dB in 0.5 dB steps. The main rotary switch sets 1dB steps whilst the 0.5 button adds half a dB to the main reading. The CUT button turns the boost amount into cut. Six strategically selected frequency choices per band are available (8, 10, 12, 15, 20 and 24 Khz on the high shelf, and 470, 360, 220, 110, 60 and 20 Hz on the low shelf).

2-POLE HIGH AND LOW PASS FILTERS

In order to keep the sub-low and ultra-high frequency content well under control, further high-pass and low-pass filters have been added on dual concentric rotary switches, at 12dB/octave. 5 frequency choices plus OFF are available on each one (10, 12, 18, 22 and 30 Khz on the low-pass, and 160, 82, 47, 20 and 15 Hz on the high-pass).

THIS IS WHERE THE MAGIC LIVES.

The Symph EQ would have been an awesome sculpting tool just as it has been described above, but it turns into a monster piece with the following 3 additions:

• It features the same exclusive Carnhill input transformers made in Oxford found in the Successor.
• Its outputs are driven by 73-type Class-A output amplifiers, built with the same Carnhill St´Ives output transformers as the rest of the family.
• Most importantly and, here is where the Symph EQ really shines, it has built in Mid Side (M/S) capabilities.

M/S EQUALIZING CANNOT BE RIVALED.

Nothing comes close to M/S equalizing a mix. It allows the user to process the center and the sides independently. The benefits of such processing are hard to believe. You can brighten your mix without making your vocals sound harsh, or even tighten the stereo-image’s bass content without making your bass or kick sound weak! These are just a few examples of the Symph EQ M/S power!

The response of the Side high pass filter has been made elliptical as in the vintage disk cutters for precise frequency response. 

THIS IS WHAT YOU GET WITH THE SYMPH EQ

• Custom Carnhill Oxford input transformers, and custom Carnhill St Ives output transformers, both exclusively made for Heritage Audio.
• A high-end, 73-style Class-A output stage.
• All controls use high-quality rotary switches for 0.5dB precision equalizing.
• Mid-side processing allows for precise center bass management and high boosting hard panned sources without affecting center ones such as vocals, snare, etc. Side high-pass filter turns into elliptical type when in M/S, as implemented in vintage disk cutters.
• Stereo and M/S inputs and outputs, all balanced and ground free (unbalanced compatible) on gold plated XLRs.ON, M/S or stereo mode and individual hard BYPASS per channel.
• Fully manufactured in the EU.

Heritage Audio is proud to announce the HA-609A, a modern, improved take on the classic tracking/mixing diode bridge compressor.  As with the other products in their Elite Series, the HA-609A takes advantage of the latest in manufacturing technology to offer an unprecedented value without compromising audio quality — all built at the Heritage factory in Spain.

The HA-609A is a modern take on the classic transformer coupled diode bridge compressor/limiter design, with several improvements brought in to accommodate the modern workflow.  While some classic iterations of this design utilized some IC chips and a class A/B amplifier stage, the HA-609A features an entirely discrete, class A design and a total of three Carnhill/St Ives transformers per channel.  The addition of a fast attack mode for both the compressor and limiter section allow the HA-609A the flexibility to handle individual tracks as well as groups and 2-bus program material. Thanks to a proprietary system of diode bridge gain reduction cells introduced with the highly regarded SUCCESSOR, the HA-609A has better channel matching than any earlier incarnations; while the use of rotary switches and high quality, stepped pots allow for easy recall and maintain a perfect stereo image.

The best of both worlds.

Introducing Heritage Audio’s HA-81A: a new mix of 2 classic console´s circuits.

The HA-81A Elite is a channel strip that combines an all discrete, Class-A 73-style mic preamp with an extremely versatile and musical console style equalizer — arguably the trick for obtaining instant classic sound for all recording engineers.

The mic preamp that meets the demands.

The HA-81A’s preamp section is an 80 dB, all discrete Class-A design with Carnhill/St. Ives input and output transformers, exactly the same one found in the other Elite Series modules.

The preamp features gain, output trim, -20db pad, polarity reverse, and +48v phantom power.

The best console´s style equalizer ever made.

The HA-81’s equalizer section is an exceptionally musical 4 band, inductor-based equalizer with high and low pass filters. Where 3 band equalizers such as the typical 73-style exceed at musicality but may get short of features, the HA-81A EQ equally excels on both. Extreme control over Shelf or Bell response curves on the high and lows, dual Q on both mid bands, with dedicated high and low mid ones, and a range of 40 frequency selections to choose from.

Hybrid design. Heritage quality.

The Heritage HA-81A utilizes only rotary switches and precision, concentric potentiometers. And like all of the products in our Elite range, the HA-81A is built with the most cutting edge methods in manufacturing and design, without ever compromising audio quality or cutting corners — all at the Heritage headquarters in Spain.

Why settle with sterile VCAs in your mix or instrument bus duties now that the Successor is available?

“Feel how your separate tracks interact and blend together in a way not possible when master bus compression duties are relegated to the mastering stage.”

Traditionally bus compression has been taken care of by VCA style devices, based on ICs, which are wholly unrelated to the warmth, fatness and the character associated with discrete Class A technology, including chunky transformers and diode bridge-based gain reduction.

The Heritage Audio Successor brings all these and then more:

A fully Carnhill transformer coupled input and output unit, the new Successor is a true stereo diode-bridge based bus compressor with advanced sidechain filtering and built-in parallel processing capabilities, sharing the class A ´73 type output stage that Heritage Audio is famous for.

Based on legendary vintage diode bridge designs, it keeps the sonic character of such units, but the added features make it a new beast on its own and will make your mixes shine in modern production environments. Ultra-fast attack and releases allow for larger than life drum bus compression sounds, while the complex sidechain filter lets you tailor your mix in ways not previously available.

“Snare drums can be more present and the stereo image widens as there is more natural room for tracks to breathe.”

From FET like, all-buttons-in drum sounds (now in stereo!) to VCA style mix bus with added warmth and fatness only transformers can bring, the Heritage Audio Successor is designed to stay hooked up to your mix bus and make your mixes shine through.

“Now vocals stand out in the mix without being overwhelming or mudding out your guitars or other instruments”.
