Terminal Strip Connections; Power Input - QSC DCM series User Manual

6. Terminal Strip Connections

The terminal strip includes convenience connections for a powered sub-woofer output, a Hearing
Impaired audio output, and on the DCM-2 and 3, a remote control on/off logic connection (EX)
for the surround decoder system.
The powered subwoofer output (SUB OUT), contains the exact same signal as the subwoofer
output used on DataPort G. It is assumed that you use either DataPort G or the terminal strip con-
nection, but not both at the same time. Due to obvious reasons, this connection will not be able
to be monitored or included any of the Fault Analysis functions because there are no connections
back from this external speaker.
WARNING: When using a powered subwoofer, there is no fault sensing available to warn a pro-
jectionist of a system connection problem.
The Hearing Impaired output is a single mono audio output which contains a mix of the L,C, and
R positional signals (Center = +6db compared to L&R). This is usually connected to a special cine-
ma system which supplies headphones to people with hearing difficulties. This can also be used
as an input signal to a powered speaker for remote monitoring of basic L/C/R signals in larger
projection booths.
On the DCM-2 and 3, one connection on the terminal strip (labelled EX) allows a remote on/off
signal to come from an external surround decoder. This routes the surround signals (I/O) to the
"TO SURROUND EX DECODER" connector or directly to the DCM DataPort connections.

7. Power Input

The power connector uses a standard IEC power cable. Since the DCM series uses a switching
power supply, a wide range of AC power can be accepted without affecting system performance.
Please refer to the specifications in Appendix 3 for the input voltage range and tolerance. Refer
to the back panel labeling for proper fuse ratings.
