2 Channel Professional Audio Amplifier Crestron
CNAMPX-2X60
PWR Indicator
This LED (green) is illuminated when 24VDC via the Cresnet connector is supplied
to the CNAMPX-2X60.
NET Indicator
This LED (yellow) indicates that the SIMPL program currently loaded in the control
system has a network device defined at the same NET ID code as the CNAMPX-
2X60. The LED flashes when communication with the Cresnet system and the
CNAMPX-2X60 is occurring.
(Chassis Ground)
Use this chassis screw to connect the audio device(s) common ground(s) to the
CNAMPX-2X60.
NET
The 4-pin network connector is used to connect the CNAMPX-2X60 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-
2X60 and activate the room outputs. This button functions only when 24VDC is
applied to the NET connector. The LED (red) illuminates when the OVERRIDE is
activated.
Power Connector and Fuse Compartment
The power connector provides AC operating power to the CNAMPX-2X60 via the
supplied power cord. The fuse electrically protects the internal circuitry from power
overloads and is located (a spare fuse is included) within the compartment above the
power connector.
INPUTS
The two RCA connectors are typically used to connect unbalanced pre-amplified
audio to the CNAMPX-2X60. The left channel audio is input to the LEFT connector
(with the white center insulator); the right channel audio to the RIGHT connector
(with the red center insulator).
4 – 8 OHM OUTPUTS
These two pairs of speaker dual-binding posts output the left and right amplified
audio to the corresponding 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 spade lugs.
