The Buzz Audio MA-2.2BTX Preamp has all the same well-loved features as the standard MA-2.2B, but features a Lundahl output transformer, providing a warmer tone than the original.

The circuitry used in the MA-2.2B preamp was developed by Buzz Audio designer Tim Farrant in the 1990's and was dubbed "True Class A". The resulting BE40 series of amplifiers exhibit a very wide frequency response (into the megahertz ) and ultra-fast slew rates (140V/uS) even at 60dB of gain. These attributes, plus the inherently low distortion provide the exceptionally pure top-end sound of the MA-2.2B.

In addition, the over-engineered power supply design with localized Class A regulators for each amplifier stage supplies the grunt needed for an authoritative and accurate bottom end - it sounds tight and never overblown.

FEATURES:

Lundahl amorphous core LL1684 output transformer
Functions are controlled with illuminated push button switches with "clickless" operation -- no more thumps on the output.
The gain pot has been replaced with a calibrated 24 position Elma switch for accurate stereo matching between channels.
Useful 19 segment peak output level meter.
Original audio and power supply design of the MA-2.2 has been retained.
