7 Channel Surround-Sound Amplifier Crestron CNAMPX-7X200
(Chassis Ground)
Use this chassis screw to connect the audio device(s) common ground(s) to the
CNAMPX-7X200.
NET
The 4-pin network connector is used to connect the CNAMPX-7X200 to the Cresnet
system. Refer to “Network Wiring” on Page 6 when making connections to the ports
labeled NET.
OVERRIDE/SETUP Button and Indicator
The OVERRIDE/SETUP button is used to activate AC power to the CNAMPX-
7X200 and activate the room outputs, overriding program control. This button
functions only when 24VDC is applied to the NET connector; the Master Switch and
front panel POWER switch must also be set to their On positions. The LED (red)
illuminates when the OVERRIDE function is activated.
Power Connector
Provides AC operating power to the CNAMPX-7X200. The connector is a 20 Amp
IEC connector. U.S. models require a dedicated 20-Amp line and receptacle. Use
only the supplied power cord, or equivalent, to connect to the AC power source.
Master Switch
This 20-amp magnetic circuit breaker (10-amp on international version) electrically
protects the internal circuitry from power overloads.
INPUTS
The seven gold plated RCA connectors are typically used to connect single-ended,
line-level pre-amplified audio to the CNAMPX-7X200.
4 – 8 OHM OUTPUTS
These seven pairs of speaker dual-binding posts output the amplified audio to the
speakers. The audio positive posts have red screw-on caps and the audio negative
posts have black screw-on caps. Each post is gold-plated and accepts bare wire or
banana plugs.
Front Panel Power Switch
The front panel of the CNAMPX-7X200 contains a power switch with an LED
indicator. This two-position switch turns operating power to the CNAMPX-7X200
circuitry on and off. It must be positioned to ON when the unit is to be controlled by
the control system. When the Cresnet system 24VDC is applied to the NET
connector on the rear panel and this switch is set to ON, AC power is applied to the
unit and the switch’s LED (green) illuminates.
