In reality, it is normal forthe surround channels to operate occa-sionally, and often to be silent. Moviedirectors and sound mixers typicallyuse these channels only when needed tocreate an effect or establish ambience.Artificially increasing the volume levelto the surround channels may destroythe illusion of surround audio and addunwanted noise to your system.Tuner OperationThe AM/FM tuner is extremely flexible,and offers a number of options.
