Unity Gain
The unity gain setting lets you use a stereo pre-amplifier in a multi-channel AV system.
In such an installation the AV processor is a source to your stereo pre-amplifier.
If you are setting up an AV processor as one of your sources and the front speakers are going to be channelled through the stereo pre-amplifier, set unity gain to Yes. In all other cases, set to No. No is the default setting.
To change a source from normal mode to Unity Gain mode, use the Konfig application/Configuration/Source Setup. Linn Konfig manual
NOTE:If unity gain is set to Yes for a source other than an AV processor, the volume level from your pre-amplifier will be very high, non-adjustable and could damage your loudspeakers.
