Volume Adjustment - Extron electronics SSP 7.1 User Manual

Volume Adjustment

5 Volume adjustment knob and LED bar or analog input gain level control and LED
bar — Use the rotary encoder to adjust the output volume from 0 (-100 dB) to 100 (0 dB).
The default setting is 50 (-50 dB).
The degree to which the volume is incremented
or decremented for each step the encoder is
turned depends on the current volume setting
(see the last column in the table below).
As the volume increases or decreases, the LED
bar lights to indicate the current volume range,
as shown in the table below. As the volume is
increased or decreased within a volume range,
the top LED to be lit flashes once. If the knob is
turned past maximum volume, all 8 LEDs flash,
for as long as the knob continues to be turned.

Analog Input Gain Level
Alternatively, the rotary encoder controls the
gain level of the analog signal on input 5.
Analog input gain is adjustable from 0 dB (fully
counterclockwise) to +24 dB (fully clockwise).
To adjust input gain, press and hold the Input 5
button, while turning the rotary encoder.
NOTES:
If the gain level is too high, clipping may occur. When clipping occurs, the red LED

summed (in the digital domain), which can cause a boost in level up to 6 dB. This type
of clipping does not cause the clip indicator LED to light but is audible. If using a mono
mode, it is recommended that the input gain be reduced by 9 dB below clipping to
prevent clipping from occurring.
All LEDs blink if user tries to turn the knob further.
