General

Avalon's AD2022 is the fourth generation of this popular double mono microphone preamplifier; it has the transparency of the M2, M22 and the M5 but with a bunch of extra features. For starters, it's equipped with an improved Class A power supply, two Hi-Z instrument inputs, and a variable high-pass filter.

About the Avalon AD2022 preamp

This preamp offers two discrete, high-voltage, symmetrical Class A signal amps per channel. The first is in a cascade FET configuration and the second is fully bipolar. Together, they

share the available gain, which ensures even higher headroom, excellent transient response, and double the signal bandwidth.

Microphone inputs, outputs and metering

Avalon's AD2022 features two instrument inputs on the front and mic inputs with 48-volt phantom power on the rear. It's equipped with a -20dB mute and a passive high-pass filter for eliminating unwanted noise from wind, static and vibrations at sub sonic frequencies.

All the outputs on the AD2022 are balanced. Two large analogue VU meters give you an accurate overview of the incoming signal, and two LED indicators warn you when you surpass the 0dB or +20dB mark.

Radial Introduces the McBoost Preamp for Dynamic and Ribbon Microphones

Wednesday 11 November 2015 By Lizanne

It's a common occurrence in the studio or during live performances - you make a recording, but the signal is low, the fader on your console is on max and you're out of headroom. The signal is simply too weak and starts to distort when you try to amplify it with a compressor or gain plugin. Radial comes to the rescue with the McBoost - a microphone preamplifier that will add up to 25 dB to the incoming signal, ideal for consoles or audio interfaces that need a little extra oomph!
