Input gain trim
The relative levels of the inputs can be adjusted by gain trim. This allows each to be adjusted so that each sounds the same in terms of average loudness when you switch between them. Pick the loudest sounding source and trim its level until it matches the average perceived level of the others. Repeat this process if other sources also stand out as louder than the average.
Fixed level inputs
Any input of the 840A is able to be set for fixed gain. Whenever this input is selected the gain will automatically go to this value and will not be adjustable by the volume control. This feature allows the 840A to be effectively used as a stereo power amplifier (for that selected input only). For example, as well as operating as a pure stereo amplifier, the 840A can provide the amplification for the front left and right channels of a surround sound setup with an AV receiver providing amplification for the other channels and controlling the overall system volume.
When listening in stereo use the 840A and connected stereo sources as normal for best possible sound quality. For surround sound, select the fixed level input you have chosen on the 840A and now use the AV receiver to control the volume, select connected surround sound sources etc. You may wish to
