a. If one or more output LEDs are lit AND the +dB LED is lit, press and release the button repeatedly until the highest-numbered lit output LED goes out. Count the button presses. In example 8, assume a value of +8 dB. It will take three presses of the button for the Output 1 LED to go out.

If one or more output LEDs are lit AND the –dB LED is lit, press and release the button repeatedly until the highest-numbered lit output LED goes out. Count the button presses.

If the +dB LED is lit and NO output 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 output 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.

b. Return to the original audio gain setting by pressing and releasing the or button (the opposite of the button you pressed in step a) the same number of steps you pressed the opposite arrow button in step 1. In example 8, this means pressing 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 example 8:

Output 1 LED:

6 dB

+ 2 presses:

+2 dB

 

8 dB

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

3.

Press and release the

button once to decrease the audio level (figure 3-33).

 

The

LED flashes each time the button is pressed

Press and release the button several more times to continue to decrease the audio level (figure 3-33). Note the output LED, +dB LED, and –dB LED changes that occur each time the button is pressed and released.

Figure 3-33 shows the result of pressing the button a total of 9 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.
