The A-RACK 8+1 is the result of many requests for a multi channel mic preamplifier system with the same sound as the venerable MA-2.2 True Class A preamp. The A-RACK is a modular design whereby modules can be removed even with the unit powered and it can currently be equipped with up to nine MA-1.5 preamp modules.
Bal Mode Min Gain = +22dB (+2dB with pad in)
Bal Mode Max Gain = +70dB
Unbal Mode Min Gain = +16dB (-4dB with pad in)
Unbal Mode Max Gain = +64dB
Maximum Output Level = +32dBu in Bal Mode, +24dBu Unbal Mode.
Frequency Response = 2Hz to 250kHz @ 20dB gain (-3dB).
= 20Hz to 250kHz @ 65dB gain (-3dB).
Harmonic Distortion = less than 0.008%100Hz to 10kHz.
Slew Rate = typically 140 V/uS, @ +20dBu output level.
EIN = -133.5dB A wtg, 150ohm source Z.
Signal to Noise Ratio = -74dB A wtg, input shorted.
CMNR = 100Hz-80dB, 1kHz -80dB, 10kHz-70dB internal trims.
Module to Module Crosstalk = below noise.
Input Impedance = 3k ohms/1k2 ohms switchable.
Controls = Gain, Solo, Mode, Mute, Input Impedance, 20dB Pad, Phase Reverse, Phantom pwr.
Indicators = Peak Level @ +18dBu (internally adjustable)
Connectors = In-XLR3F, Out-XLR3M.
Size = DIN 41612 standard 8 HP wide.
Power requirements = Must be fitted into A-RACK module rack bin.

"I surrender, I have found the Holy Grail of preamps, I'm sorry Neve but you are now #2. This is truly no hipe, no bullshit, just serious headroom and truth. Finally somebody got it in a big way and you can quote me on that."
