Optimizing the Audio
Each audio level for each input can be adjusted within a range of -18 dB to +24 dB, so
there are no noticeable volume differences between sources and for the best headroom
and signal-to-noise ratio. The volume for each local audio output can be adjusted from full
loudness to effectively muted. Adjust the levels as follows:
1.
Connect audio sources to all desired inputs and connect the local audio outputs to
output devices such as audio players. See “
”, in the “Installation” section.
For best results, wire all of the inputs and the outputs balanced.
2.
Power on the audio sources, the switcher, and the audio players.
3.
Switch among the inputs (see “
”, on page 31), listening to
the audio with a critical ear or measuring the output audio level with test equipment,
such as a VU meter.
4.
As necessary, adjust the input audio level of each input (see “
”, on page 48) so that the approximate output level is the same
for all selected inputs.
5.
Tie an audio input to each local audio output.
6.
As necessary, adjust the output audio level of each output (see “
