Selectable functions of the mainboard DSP
The DSP on the mainboard provides selectable functions. A description of the indi-
vidual functions can be found as of page 44.
The functions are determined in the DSP configuration ( =ym). In Tab. 16 all the
possible combinations are listed, with the maximum number of voice channels. For
this the DSP chip on the mainboard has to be loaded with different firmware. Addi-
tional functions require the use of one or more DSP modules. Some of these func-
tions are subject to a licence.
