input 5.

 

 

 

 

A VU meter connected to output 1 indicates that the adjusted level is approximately +9 dB above the –10 dBV internal level.

The power LED lights steadily or blinks off only occasionally to indicate that the adjusted level is too high.

In this example, the LEDs indicate gain in the +6 dB to +10 dB range.

If the +dB and –dB LED are both lit they indicate an input gain of 0 dB. Otherwise, you can determine the exact gain or attenuation using the following procedure:

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

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