Connections (continued)

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.

Connect other end of cable according to equipment manufacturer’s instructions.

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.
