Gilderfluke&Co Mp3-50 Audio & Show Controllers - Manual (Page 27)

of a Mp3-50/8 or Mp3-50/40.
Mp3-50/8: This connector is used for the optically isolated trig-
ger inputs of the Mp3 Player, but these are not normally
used to control the Mp3 Player. The same connector is also
used as the eight Show Control outputs. The inputs to the
Mp3 Player are typically configured not to do anything,
and the ‘MCU’ Show Control Trigger channel is used instead
for controlling the Mp3 Player. This leaves all eight of these
pins available for Show Control Outputs.
If you need to use a switch input to mute or stop the
audio, it can still be wired into this connector. The input to
the Mp3 Player is then configured for the desired function.
The corresponding Show Control output is left unpro-
grammed, so that show data does not interfere with the op-
eration of the Mp3 Player.
Mp3-50/40: This connector is also used as the optically isolated
trigger inputs the Mp3 Player, and the last eight of the forty
Show Control outputs. Other than that, it is identical to a
Mp3-50/8.

For a Mp3-50, the 1/4 J6 input is strictly a Mp3 input. It is opti-
cally isolated. It can be set to run from an external power source
or the same power as the Mp3-50, Mp3-50/8 or Mp3-50/40 (de-
fault configuration). This is selected by moving the switch on the
bottom of the Mp3-50, Mp3-50/8 or Mp3-50/40. The ‘external’
