Operation, cont’d

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.

a. If one or more input LEDs are lit AND the +dB LED is/are lit, press and release the button repeatedly until the highest-numbered lit input LED goes out. Count the button presses. In this example, 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 is/are lit AND the –dB LED is lit, press and release the button repeatedly until the most highest-numbered lit input LED goes out. Count the button presses, each of which represents a 1 dB increment.

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, each of which represents a 1 dB increment.

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, each of which represents a 1 dB increment.

b. Return to the original audio level setting by pressing and releasing the or button (the opposite of the button you pushed in step 3a) the same number of steps you pushed the opposite arrow button in step 3a. In this example, this means pushing the button three times.

c. Add the dB value indicated by the highest-numbered lit output LED (no output LEDs lit and both dB LEDs lit = 0 dB) and either of the following:

•The number of button presses from 0 dB, or

•The number of button presses from when the highest-numbered output LED lit. In this example:

Output 1 LED:

6 dB

+ 2 presses:

+2 dB

 

8 dB

d. The lit +dB or –dB LED indicates the gain (+) or attenuation (-).

4. 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 3-5

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.

-dB +dB

Indicates 0dB to -6dB range

LED key: = off

5. Press and hold the Audio Conf/Save button until the Audio LED goes off. The input LEDs stop displaying the audio level range, the +dB and –dB LEDs go off, and the selected input LED lights.

Press

and release.
