Optimizing the Audio

NThis section addresses only the front panel controls for optimizing video. For setting the digital signal processor adjustments, see “Optimizing the Audio” in chapter 5, “Switcher Software”.

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”, 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 a configuration”, 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”, 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 output (see “Viewing and

 

adjusting the output volume”, in this chapter).
