Viewing and adjusting the input audio level (HVA models only)

On HVA models, the audio level of each input can be displayed and adjusted through a range of -15dB to +9dB to ensure that there is no noticeable volume difference among sources. The audio level can be adjusted from the front panel or by using Extron’s Windows-based control program.

1.

Press and hold the Audio button until the Audio LED begins to blink, then

 

release the Audio button.

2.

Press and release an input button to select an input. The audio level for the

 

selected input is displayed in the output LEDs and the polarity (+ or -) is

 

displayed in the View or Esc LEDs.

3.

Press and release the Esc ( ) and View ( ) buttons to increase and decrease

 

the audio level.

4.

Press and release the Audio button to exit the audio display and adjust mode.

 

The Audio LED stops blinking and turns off.

 

 

1.

There is one audio level setting per input. The audio level setting is

 

 

 

 

 

shared by the left and right audio inputs.

 

2.

The audio level settings are stored in non-volatile memory. When power

 

 

 

is removed and restored, the audio level settings are retained.
