Digital Section
The sound of the Mastering Equalizer is of course based on the quality of its analog filters, precisely matched capacitors and inductors. But all the control and user interactions are performed in the digital domain. This allows us to incorporate options and possibilities not found in any standard analog equalizers:
Save and recall presets from on-board memory (400 slots available) Instant reset of all parameters Rapid, precise and repeatable adjustments Precisely linked stereo operation with the ease of a single control DAW automation and recall of all available parameters
The digital section of the Mastering Equalizer is based around high speed, 32-bit micro-controller, with dedicated firmware programmed into its memory (with the possibility of updating the firmware via USB connection). It controls the parameters af all analog filters, watches over the user interface, presets management, audio measurement, USB connectivity and other Mastering Equalizer functions.

Front panel and LCD touchscreen
The front panel of the Mastering Equalizer is build around big LCD touchscreen, that allows you to control almost all functions available in the device. It will show you live representation of the EQ curve and allow you to adjust filter gain and frequency with the touch and drag of your finger (check unique Frequency Search function!). Apart from that, you can also monitor input/output levels, access the FFT real time analyzer or store and recall presets using on-screen QWERTY keyboard.
