IMPORTANT NOTE
• Use a ¼-inch TRS plug for
balanced sends/inserts.
• Use a ¼-inch TS plug for
unbalanced sends/inserts.
• Mixing balanced and unbal-
anced connections may result
in a 6 dB loss of gain.

Tests performed using an Audio Precision
System One model 322 or equal.
*Below approximately 200 Hz the feedback filters
become slightly wider to increase the feedback and
rumble capture speed at these low frequencies.

anced connections may result
in a 6 dB loss of gain.
