¹ Below approximately 200 Hz the feedback filters become slightly wider to increase the feedback and rumble capture speed at these low frequencies.

² Note: Inputs may be balanced or unbalanced.  For maximum output capability, outputs must be balanced (XLR or TRS).  If either side of an output is grounded, the peak output and dynamic range will be reduced by 6 dB.

³ Signal-to-noise ratio is the ratio of the maximum undistorted signal by specification (26 dBV RMS sinewave) to the noise floor
