Preampliﬁer

212L Gain

This knob adjusts the amount of gain applied to the input

signal. The available range is 30 dB to 65 dB. The de-

fault value is 40.5 dB.

212L Pad

When enabled, the input signal level is attenuated (low-

ered) by 20 dB. The pad is engaged when the red indi-

cator is lit.

Pad can be used to reduce signal levels when undesir-

able overload distortion is present at low preamp gain

levels.

Note: The 212L Pad is available for both the mic and

line inputs.

212L Meter

The Meter indicates the signal level at the output of the 212L preamp module.

212L Phase

The Phase (ø) button inverts the polarity of the signal. The polarity is inverted

when the green indicator is lit. Leave the button off (unlit) for normal polarity.

Unison Impedance

When API Vision Console Channel Strip is used in a PREAMP insert

within the Apollo Console application, the hardware input imped-

ance of the Apollo mic preamp is switched to 1.5k Ω (the value of

the 212L hardware module) for physical, microphone-to-preamp resistive in-

teraction.
