The AD2022 features split low-ratio primary windings which are carefully combined within a custom mu-metal core for extended smooth frequency response and very low distortion. 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.
Two 100% discrete, high-voltage, symmetrical Pure Class A signal amplifiers are utilized per channel of the AD2022. 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 offers peak indication at 0dB and +20dB.
