The LED on the front of the PGA04 indicates the load on the PGA04s’ load box. The factory setting is such, that the 
load box automatically gets deactivated when you connect a speaker to the rear “THRU” socket of the PGA04. Thus 
the LED chain is also inactive.

You can however modify this behavior with a simple jumper within the PGA04.
If you change the position of the jumper, the LED chain will display the input level instead of the load on the load box. 
It will thus always display the input, regardless of whether a speaker is connected or not.

Follow these instructions to change this setting:

Please only make this change if you are con

fi

 dent of being able to do so. Otherwise please contact a certi

fi

 ed techni-

cian.

 

STEP 1:

Remove the top cover of the PGA04 and 
locate the jumper as shown below.

A: 

The LED chain displays the load on 

the load box - this is the factory setting.

B

: The LED chain shows the input level at 

all times

STEP 2:

For the LED Chain to display the Input level, 
pull the jumper out using a pair of 

fi

 ne twee-

zers and stick it back on in the alternative 
position.
