Description
The Avalon ad2022 is Avalon S’s fourth generation of fully discrete, symmetrical pure Class A microphone preamps. The Dual Mono ad2022 includes the original’s sonic capabilities and the transparency of the M2, M22 and M5 preamps Plus several additional functions, including selectable microphone cable Charging source for optimized / matching microphone, improved regulated high voltage class A power supplies, two high-Z instrument inputs, variable-passive high-pass filter, Teflon / silver wiring and double plating on circuit boards for a low level of superior signal transfer. Pure class a symmetrical design, two mic channels and instrument inputs Hi-Z Gain Switched 4dB steps plus +/- 3dB Fine matching selectable trailing edge, Split low-ratio primary windings are carefully combined within a custom mu-metal core for smooth extended frequency response and extremely low distortion. Silver sealer relays are used for a minimal invasion signal. Input signal selector, high-pass filter, reverse polarity-phase, + 48V supply, and 20 dB attenuator input all utilize local relay seal operation. A passive variable high-pass filter provides minimal phase shift design that prevents rumble, low-frequency wind noise, and mechanical vibration at sub Sonic frequencies. symmetrical Pure + 48V power supply and 20 dB attenuator input all utilize local relay seal operation.
