Audio Configuration

Step 1

For the Lineout and Preamp outputs, select mono or stereo audio, and select ‑10 dBV (unbalanced) or +4 dBu (balanced) via RS‑232 control.

Default: -10 dBV.

MID	Normal: a blinking LED indicates that the level
MIN	is set properly for maximum power output.

Signal: when lit, this indicates that a signal of at least -20 dBV (-18 dBu) is detected at the input.

NOTE Increasing the audio level beyond the point at which the Mid/normal LED blinks may result in a distorted output signal.

NOTE In setup mode a blinking or lit Mid/normal LED indicates that the power amplifier is capable of delivering maximum power output.

NOTE You may not need to adjust the per-input gain, because the default input gain adjustment is set for consumer audio sources such as VCRs, DVD players, and laptop computers.
