3. Press and release the output 7 button (figure 3-40).

The input buttons display the selected output's audio volume level.

Each lit input button indicates up to 14 percent of the total input volume is applied to the output. Each unlit or background illuminated input button indicates 1 dB to 7 dB of attenuation is applied to the output.

In this example, the green input buttons indicate that the switcher is outputting approximately 28 percent of the applied audio input. The unlit input buttons indicate an audio volume attenuation of approximately 42 dB.
