Gilderfluke&Co Mp3-50 Audio & Show Controllers - Manual (Page 28)

setting is used when you want to completely isolate the Mp3-50,
Mp3-50/8 or Mp3-50/40 from the switch closures that control it.
On a Mp3-50/8 or Mp3-50/40, this input/output is almost al-
ways run in the ‘Internal’ power mode. The only exception to this is
if you are going to be running the devices controlled by these
eight Show Control outputs from a different voltage from the rest
of the Mp3-50/8 or Mp3-50/40. As an example, it the Mp3-50/8
or Mp3-50/40 is running from 24 VDC, and you need to control
eight 12 VDC relays, you can power this one port from a 12 VDC
power supply separate from the main one (you will need to con-
nect the grounds of the two power supplies).
10) Left Line Output: Female RCA jack. This is one of the two line level
outputs from the Mp3 Player. It is used for attaching an external
amplifier to the Mp3-50, Mp3-50/8 or Mp3-50/40.
11) Right Line Output: Female RCA jack. This is one of the two line
level outputs from the Mp3 Player. It is used for attaching an ex-
ternal amplifier to the Mp3-50, Mp3-50/8 or Mp3-50/40.
12) J8 ‘A’, ‘B’, ‘C’ & ‘D’ inputs: These are four optically isolated digital
inputs which can be used to start, stop, pause or select specific
show sequences to play on the Show Control of the Mp3-50/8 or
Mp3-50/40.
