ISP Technologies CS 650 - Manual (Page 10)

Insert the CS650 into the ceiling tile hole and through the tile bridge opening. Begin to
tighten the installation screws. As you start to turn each screw the Angle Lug Clamps
(A) will rotate outward to engage the tile bridge and ceiling material (C).
CAUTION: Do Not Over Tighten the Clamps. Too much torque may snap off the lug,
causing the speaker to not seat securely. A snug fit is all that is necessary to assure
proper performance.
Remote Level Control
As mentioned above, the CS650 allows the use of 3 options for remote level control. If
a single CS650 speaker is to be controlled use ISP Technologies RM10 remote level
control. The RM10 is designed to control a single Ceiling speaker and requires one Cat5
cable connection between the CS650 and the RM10. The remote level control will allow
adjustment of the level of the CS650 from zero to the maximum level set on the Master
Control Module. The RM20 allows connection to two CS650 speakers and can control
them as a stereo pair or as dual mono speakers. The RM20i allows connection to two
CS650 speakers as above but also includes a 1/8 inch RTS input jack to connect to an
iPOD or other audio device. The figure below shows the connections with two CS650
speakers and an RM20i Remote Level Control. Note: The CS650 ships with an
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.
