Optimizing the Audio (Audio Switchers)
Each individual input audio level 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. Adjust the audio gain and attenuation as
follows:
1
.
Connect audio sources to all desired inputs and connect the audio outputs to
output devices such as audio players. See Audio input and output connections
(audio models only), in chapter 2, Installation. 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 Creating ties, in this chapter), 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 Viewing and
adjusting the input audio level (audio models), in this chapter) so that the
approximate output level is the same for all selected inputs.
5
.
As necessary, adjust the output audio level of each input (see Viewing and
adjusting the output volume (audio models), in this chapter).
