By noting the status of these LEDs and counting the number of 1 dB steps you increase or decrease the audio level (step 4 and example 8, step 2a), you can determine the exact input gain or attenuation setting.

b.The Power LED blinks to indicate the adjusted audio level (compared to the internal level, -10 dBV):

•When the LED is lit most of the time, blinking off only occasionally, the level is too high.

•When the LED is off most of the time, blinking on (lit) only occasionally, the level is too low.

•When the LED blinks frequently, the level is in the proper range.

c.The < LED lights steadily when the adjustment is at the minimum level (maximum attenuation, -18 dB). The > LED lights steadily when the adjustment is at the maximum gain (+10 dB).

4.Press and release the < and > buttons to increase and decrease the audio level by 1 dB or press and hold the buttons to increase or decrease the level by 3 dB per second. The < or > LEDs flash to indicate each 1 dB level change.

NOTE: Each time you press the < or > button, wait for the < or > LED to flash

before pushing the button again. Pressing the button too rapidly may not increment or decrement the audio level.

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.

NOTES: • 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.Select Audio Setup mode: Press and hold the Audio Setup (I/O) button for approximately 2 seconds.

Press and hold the button.
