AV dsp amp

channel that contains any valid audio is selected and becomes the new input 
source. But if you put in the USB cable but you want to use the analogue input 
you can force the analogue input to be used. This can be done for all inputs, the 
options Analogue, SPDIF and USB Audio.
When the module selects one of the inputs this is shown by the active input 
lights. 
Under the Setup select part the system setup can be selected. There can be 
chosen between:

2-channel

Stereo

Bridged

Master on the left

Master on the left

Master on the left

Master on the right*

Master on the right*

Master on the right*

Mid/Sub, L+R

Sub, L+R

Side, L-R

* Only on digital audio board, for analogue version cinches has to be changed 
like described in 

Hardware part’.

The output signal of the subout channel van be controlled in the  Subout

 

control  panel. Normally this will be set to L+R to use one subwoofer, but if you

 

want to use a subwoofer on both sides you can set the subout to only use left or 
right input signal.
The last thing that can be controlled in this window is volume. This can be done 
by setting the scrollbar to a desired position or by typing the value in the 
volume field , this value is send when pressed  enter .

All of the configurations made here will be redirected from master to slave, 
when presented. So there is no need to connect the slave module to the pc. 
The slave module is always the opposite of the master, so master left will set 
the slave to right. This is done automatically because the module knows whether 
it is master or slave.
Only when the module is switched off by remote all settings, like volume and 
setup, are stored in memory. 

Filter design

When you want to make some filters 
for your module they can be 
designed in the  Filter design .

 

Under view there can be switched 
between the control panel and the 
filter design window.
The following pages will give you a 
widespread instruction of the 
possibilities of the program.
