There are a number of 25-way D-type female connectors (depending upon the number of input channels) on the
rear connector panel. The connector layout varies with the configuration of input modules and mono and stereo
input modules differ in the facilities available.
lEach block of four Mono inputs has one D-type connector for external mutes, and one D-type for Mic Live
Remotes.
lEach block of four Stereo inputs has one D-type connector for external mutes, and one D-type for
Remote Stop/Starts.
The diagram opposite shows the pin labelling
(as viewed from the outside of the console).
The pin-outs of the various D-types are given below.
