INSTALLATION-
HEARING IMPAIRED CONNECTION
The Hearing Impaired output signal
is available on the screw terminal
connector on the rear of the DCM.
The output signal is similar to
levels that are output from a
standard CD player.
Output Level
-11.8 dBu
(200 mVrms)
Use balanced audio connections and high-quality, shielded, balanced audio
cable for interconnecting the DCM and Hearing Impaired equipment. Balanced
connections are less prone to noise pick-up than unbalanced connections.
POWERED SUBWOOFER CONNECTION
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 the sub channel signal
if this connection
is used.
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.
Connections: Hearing Impaired, Powered Subwoofer
