Stereo pure class-A transformer balanced microphone preamplifier with all discreet electronics.
The Avalon AD2022 is a 2U rack-mounted two channel Class A microphone preamp and DI. Using the Avalon AD2022 is simple and straightforward - just plug in and play. Under the bonnet though is where the work goes on. The twin Class A circuitry on each channel of the AD2022 is designed with the shortest signal path possible to maximise signal strength and give you the best-sounding most transparent microphone preamp you can find. Components are top spec and every care is taken to ensure that you get low noise, clean and distortion-free results every time. The AD2022 front panel layout is simple and intuitive, with variable input level and impedance controls, Pad and Phantom buttons, Phase reverse and Filter switches and a variable HPF Filter control before the rotary Output knob. Widely used by professional studios and much admired for both its operation and its product philosophy, Avalon Design is in the business of putting the best into your hands. The Avalon AD2022 preamp continues that idea, delivering a truly transparent sound.
