5. Press and release the Audio Setup button to save the level value in memory and to exit Audio Setup mode. The Audio Setup LED turns off.

• After approximately 30 seconds of front panel inactivity, the switcher saves the most recent input gain or attenuation levels and exits Audio Setup mode.

•There is one audio gain or attenuation setting per input. The setting is shared by the left and right audio inputs.

•The input audio gain or attenuation settings are stored in non-volatile memory. When power is removed and restored, the audio level settings are retained.

Example 8: Adjust the input audio gain

The following steps show an example in which an input audio level is viewed and adjusted. The example shows the front panel indications that result from your actions.

1. Press and hold the Audio Setup (I/O) button for approximately 2 seconds (figure 3-31) until the Audio Setup LED lights.

A VU meter connected to output 1 indicates that the adjusted level is approximately +9 dB above the –10 dBV internal level.

The power LED lights steadily or blinks off only occasionally to indicate that the adjusted level is too high.
