The AD2022 is Avalon’s fourth generation of fully

Pure Class A microphone preamplifiers. The dual mono

AD2022 includes all the original sonic capabilities and

transparency of the M2, M22 and M5 preamplifiers plus

several additional features, including selectable microphone

source loading for optimized cable/mic matching, improved

high-voltage Class A regulated power supplies, two HI-Z

instrument inputs, variable-passive high pass filter,

teflon/silver wiring and doubled plated circuit boards for

superior low level signal transfer.


The AD2022 incorporates the most advanced highperformance

microphone transformer available. Split low-ratio

primary windings are carefully combined within a custom mumetal

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, polarityphase

reverse, +48v power and the 20dB input attenuator

all utilize local sealed silver 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.


Two 100% discrete, high-voltage, symmetrical Pure Class A

signal amplifiers are utilized per channel. The first operates in

a cascaded-cascode FET configuration while the second stage

amplifier is fully bipolar. The twin amplifiers share the total

available gain requirement. This shared architecture increases

the high level headroom capability, improves transient

response and doubles the internal bandwidth of the ultra high

performance Pure Class A signal amplifiers.


High-current DC coupled, Class A discrete amplifiers are

utilized for the output drive interface with +36dB capability into

all known loads. Two large, high-quality analog VU meters

indicate accurate signal readings while bi-color LED’s offer

peak indication at 0dB and +20dB. The AD2022 will make your

recordings musical masterpieces!
