SETTING GAIN CONTROLS

Each channel pair on the ZX460 is equipped with a variable gain control. The gain control is provided for level matching purposes; it does not give the amplifier any more power by turning it up – its purpose is to adjust the sensitivity of the amplifier in relation to the output level provided by the source.

Start with the amp gain set to minimum by turning the control counter-clockwise. Turn the source level up until distortion is barely audible – this will be at about 75-80% of full volume. Raise the amplifier gain until distortion is just audible. The gain is now set correctly. Check the level with CD/tape and tuner to make sure the adjustment is correct for all sources.
