If the +dB and -dB LED are both lit they indicate 0 dB. Otherwise, you can
determine the exact gain or attenuation using the following procedure.
1
.
If one or more input LEDs are lit AND the +dB LED is lit
, press and
release the
button repeatedly until the highest-numbered lit input
LED goes out. Count the button presses.
In Example 4
, assume a value
of +8 dB. It will take three presses of the
button for the Input 1 LED
to go out.
If one or more input LEDs are lit AND the -dB LED is lit
, press and
release the
button repeatedly until the highest-numbered lit input
LED goes out. Count the button presses.
If the +dB LED is lit and NO input LEDs are lit
, press and release the
button repeatedly until the +dB and -dB LED are both lit, indicating 0
dB. Count the button presses.
If the -dB LED is lit and NO input LEDs are lit
, press and release the
button repeatedly until the +dB and -dB LED are both lit, indicating 0
dB. Count the button presses.

.
Return to the original audio level setting by pressing and releasing the
or
button (the opposite of the button you pushed in step
1
) the
same number of steps you pushed the opposite arrow button in step
1
.
In Example 4
, this means pushing the
button three times.
3
.
Add the dB value indicated by the highest-numbered lit input LED (no
input LEDs lit = 0 dB) and either:
The number of button presses from 0 dB or,
The number of button presses from when the highest-numbered input
LED lit.
In Example 4
, Input 1 LED (6 dB) + 2 presses (2 dB) = 8 dB.
4
.
The lit +dB or -dB LED indicates the gain (+) or attenuation (-).
E
Press and release the
button several times to decrease the audio level
displayed in the input LEDs by 1 dB per button push. The
LED flashes
each time the button is pressed. Note the input LED, +dB LED, and -dB LED
changes that occur each time the
button is pressed and released. Figure 3-9
shows the result of pressing the
button a total of nine times to change the
value to -1 dB. Note that the +dB LED has turned off and that the -dB LED is
on to indicate a negative level.
