HARDWARE DESCRIPTION-
REAR PANEL (continued)
Terminal Strip Connections: The terminal strip in-
cludes convenient connections for output to a powered
subwoofer, a Hearing Impaired audio output, and on the
DCM-2 and 3, a remote control on/off logic connection
(EX MODE) for the surround decoder system.
SUB OUT provides 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
connection, but not both at the same time. This
connection cannot be monitored or include any of the
Fault Analysis functions because there are no connec-
tions back from this external speaker.
HEARING IMPAIRED OUT 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 cinema 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.
EX MODE- On the DCM-2 and 3, this connection on
the terminal strip 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.
IEC-type AC Power Cord Receptacle: The power
receptacle accepts a standard IEC power cable. The DCM
uses a switching power supply that accepts a wide range
of AC voltage. 85 to 260 VAC (50/60 Hz.) is the acceptable
AC voltage. The IEC connector also houses the fuses for
the DCM.

If fuse replacement is required, use only
Littlefuse #218 001 or Bussman #S5504-1A.
