6.0 Stereo I/O control
Your Intelix matrix allows a great deal of flexibility when routing and controlling stereo audio. Both inputs
and outputs can be defined as mono or stereo. This gives four possible combinations of inputs and outputs:
1) Mono input to mono output
2) mono input to stereo output
3) stereo input to mono output
4) stereo input to stereo output
In cases 2 and 4, there are input and output controls that can be used to set balance, panning and “width”
of the audio signals. These controls are explained below.
6.1 Input controls
There are two types of input controls: an input width control, and an input pan control. The input width
control is used only for stereo inputs, and the input pan control is used only for mono inputs . Their
internal workings are explained on the following pages.
6.3 Setting control values
The control values for all stereo controls ( input pan control, input width control and output balance control
are set with multiple calls to a single RS232 command: I/O Goto Pan ; this is a Class 1 RS-232 message. It
is explained in detail on page 89.
The I/O Goto Pan message has a single parameter “pan/width/balance”. The meaning of this parameter
changes depending on the nature of the target. The matrix examines the i/o flag and i/o number to determine
whether the target is an input/output and mono/stereo.
The meaning of the pan/width/balance parameter is determined as follows:
if target is a mono input the meaning is pan
if target is a stereo input the meaning is width
if target is any output the meaning is balance
There is one output control, the output balance control. It is used only with stereo outputs. The output
balance control distributes two inputs to two outputs, in proportion to the setting of the control value.
