Avalon AD2022 Preamp
The AD2022 is Avalons fourth generation of fully discrete, symmetrical Pure Class A microphone preamplifiers. The dual mono AD2022 includes the original sonic capabilities and transparency of the M2, M22 and M5 preamplifiers plus several additional features, including selectable microphone source loading for optimized cablemic matching, improved high voltage Class A regulated power supplies, two high Z instrument inputs, variable passive high pass filter, teflonsilver wiring and doubled plated circuit boards for superior low level signal transfer. Symmetrical Pure Class A design, two channels Microphone and hi Z instrument inputs Gain switched 4dB steps plus 3dB fine output trim Selectable microphone input impedance matching Low noise 126dB EIN Ultra high quality, low ratio, balanced input transformer Balanced, high current Class A output to 36dB Large illuminated analog VU meters and twin peak LEDs Regulated phantom power supply 48v Input polarity phase reverse High headroom 36dB input before overload Input 20dB pad for high level signals Sealed silver relays for all signal routing External AC 150w toroidal power chassis Fully discrete Class A regulated audio power supplies Deep, musical sound stage, transparent amplification MICROPHONE INPUTThe AD2022 incorporates the most advanced high performance microphone transformer available. Split low ratio primary windings are carefully combined within a custom mu metal core for extended smooth frequency response and very low distortion. Sealer silver relays are used for minimal signal invasion. The input signal selector, high pass filter, polarity phase reverse, 48v power and the 20dB input attenuator all utilize local sealed relay operation. A variable passive high pass filter provides a minimum phase shift design while eliminating low frequency rumble, wind noise and mechanical vibration at sub sonic frequencies.
