Powered Subwoofer
Screw terminal connections make it possible to send a balanced signal to a powered
subwoofer. This signal is balanced and the circuitry is designed for long cable runs
from the projection booth to the theater screen. The high-pass filtering and level
adjustments are done by the DCM unit.
NOTE: There will be no fault analysis or output audio monitoring available for this sub
channel.
Use balanced audio connections and high-quality, shielded, balanced
audio cable for interconnecting the DCM and Powered Subwoofer
equipment. Balanced connections are less prone to noise pick-up
than unbalanced connections.
External Speaker Connection
The monitor signal is available on the screw terminals at the rear of the DCM. This pow-
ered signal can be connected directly to an external 8-4 ohm speaker such as the QSC
AD-S52 for remote monitoring.
When using an external speaker, the factory-installed jumper powering
the internal speaker must be removed to prevent overload of the moni-
tor amplifier.
Auxiliary Input Connection
An additional input channel may be included through the AUX INPUT terminals.
ALT EQ SELECT
Closing a switch across these terminal inputs enables an alternate setting of each channel’s parametric EQ. A front panel LED
indicates when the alternate EQ setting has been selected.
Connect other end of cable according to
equipment manufacturer’s instructions.
