16 Channel Professional Audio Amplifier
Crestron
CNAMPX-16X60
PWR Indicator
This LED (green) is illuminated when operating power is supplied to the CNAMPX-
16X60.
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-
16X60. The LED flashes when communication with the Cresnet system and the
CNAMPX-16X60 is occurring.
G (Chassis Ground)
Use this chassis screw to connect the audio device(s) common ground(s) to the
CNAMPX-16X60.
NET
The 4-pin network connector is used to connect the CNAMPX-16X60 to the Cresnet
system. Review the Network Interconnection Diagram (latest revision of Doc. 5411).
OVERRIDE Button and Indicator
The OVERRIDE button is used to activate AC power to the CNAMPX-16X60 and
activate all 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-16X60 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.
CAUTION:
If it becomes necessary to replace the fuse(s), replace only with same
type, size and amperage rating.
ROOM INPUTS 1 - 8
Each of the eight pair of RCA connectors is typically used to connect the pre-
amplified audio from the CNX-PAD8 to the CNAMPX-16X60. The left channel
audio is input to the connectors with the white center insulators and right channel
audio connectors have red center insulators.
ROOM OUTPUTS 1 – 8
These eight pair 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, banana plugs, or spade lugs.
CNAMPX-16X60 Front Panel Power Switch
As shown on the next page, the front panel of the CNAMPX-16X60 contains a
power switch with an LED indicator. This two-position (ON/OFF) switch enables
operating power to the CNAMPX-16X60 circuitry and must be positioned to ON
when the unit is controlled by the control system. When the Cresnet 24VDC is
applied to the proper pin of the NET connector, power is applied to the circuitry and
the LED (green) illuminates.
