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.
Example 7: View and adjust an audio level
Refer to figure 33, figure 35, and the following
steps for an example of viewing and adjusting
the audio level. Audio gain and attenuation is
displayed differently on the CrossPoint Plus
168 and 1616, but the steps for displaying the
value are the same. For this reason, figure 34
and figure 36 show the indications displayed
on the CrossPoint Plus 168 and 1616 without
duplicating all of the actions shown in
figure 33 and figure 35.
A
Press and release the Esc button. The Esc
LED turns on for approximately 2
seconds and turns off.
B
Press and hold the Audio button for
approximately 2 seconds until the Audio
LED begins to blink, then release the
Audio button.
C
Press and release the input 5 button. The
input 5 LED lights. The audio level for
the selected input is displayed in the
output LEDs. The polarity is indicated
by either the Esc (
) or View ( ) LED
blinking.
On the CrossPoint Plus 84, 88, 124, and
128, each output LED indicates 1dB when
blinking and 2dB when lit.
On the CrossPoint Plus 168 and 1616,
each output LED indicates 1dB when lit.
The blinking Esc ( ) LED indicates a positive (gain) level. The blinking
View ( ) LED indicates a negative (attenuation) level.
