GENERAL DESCRIPTION

Global architecture

Global architecture is based upon a full 24bit audio path with 48bit core calculator running at 100 Million
Instructions per Second. Featuring:
2 analogue inputs (floating balanced) 24bit resolution ADC.
4 analogue outputs (balanced) 24bit resolution DAC.
4 sense inputs (balanced) 16bit resolution ADC.

Set-up configurations

The audio path is automatically adjusted within the NX242 according to the setups (PS15, GEOT, CD18)
chosen by the user. This will affect the delays and gain control. For instance changing the gain of a CD18
cabinet will affect two channels at a time, changing the gain on a 3 WAY cabinet (e.g. Alpha) will affect
three channels, etc.
At the time of writing, the following configurations are used (for a complete description Appendix A on
page 37 for the list of setups currently supported)

You may have noticed that certain configuration (4 passive cabinets for instance) are not supported.

to the separate manual for additional information.
