*Below approximately 200 Hz the feedback filters become slightly wider to increase the feedback and rumble capture speed at these low frequencies.
** (Note: Inputs may be balanced or unbalanced. For maximum output capability, outputs must be balanced (XLR). If either side of an input is grounded, the peak output and dynamic range will be reduced by 6 dB.
*** Tests performed using an Audio Precision System One model 322 or equal.
