CONF/SAVE

Conf/Save blinks. Release the button.

On the SW4 RGBHV A and SW6 RGBHV A only, the input 1 through 4 LEDs display the approximate audio level for the selected input. Each input LED indicates a range of 6 dB when lit (Input 1 LED off = 0 dB to 5 dB, Input 1 LED lit = 6 dB to 11 dB, Input 2 LED lit = 12 dB to 17 dB, and so on).

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

Each time you press and release the or button, wait for the or LED to flash before pushing the button again. Pressing the button early may not decrement or increment the audio level.

4. Press and hold the Audio Conf/Save button until the Conf/Save LED turns off to save the gain value in memory and exit the audio display and adjustment mode.
