OPERATION

The HDDS Master Control Module is the Master control center for distributed sound
systems using the HDDS technology. The Master Control Module includes six zones
that can be used independently or can be linked to work together allowing the system
designer the flexibility to set up any system with the desired configuration. The
speaker receives power and audio over a Cat5 cable connected to the Master Control
Module, internally converts the AC power to plus / minus 15VDC and 30VDC to power
the amplifier. The audio signal is fed to a precision differential amplifier to remove any
common mode noise, equalized and fed to D-CAT power amplifier circuit to drive both
the woofer and tweeter in the ceiling speaker. The CS651 also allows connection to a
remote level control RM10 allowing user adjustment of the speaker level. By using
remote control RM20 two ceiling speakers can be simultaneously adjusted offering
stereo control. External remote model RM20 allows an external input signal to be
inserted in to the wall mounted Remote such as an IPOD or other external device
connected via a 1/8 inch phone plug. Note: The CS651 ships with a RJ45 Jumper

plug inserted in the Remote Level Port, This jumper is required for audio to
pass if no remote level control is used. If connecting to a RM20 or RM20I
remove this jumper and connect the desired remote level control.

The CS651 is designed for use where non-plenum rated speakers can be used. Dual
slot ports tune the woofer to the enclosure for deep bass reproduction. The CS651
provides a UL94 high temperature rated enclosure. The CS651 speaker includes: a
removable steel mesh grill, built-in mounting brackets, hardware, and installation cutout
template.
