Crestron CNAMPX-16X60 16 Channel Professional Audio Amplifier
16 Channel Professional Audio
Amplifier: CNAMPX-16X60
Description
Functional Description
The CNAMPX-16X60 is a Crestron control network (Cresnet) 16 channel, 60-
Watts per channel audio amplifier. Typically installed in addition to the CNX-PAD8,
the unit provides remote system power on/off and remote zone on/off capabilities.
The CNAMPX-16X60 reports any electrical fault within itself or from a speaker
load. The voltage from each speaker terminal is monitored and ambient temperature
within the enclosure is reported via Cresnet and is available as Fahrenheit or Celsius.
These signals can be used to reduce the audio volume, activate an external cooling
fan, or turn the unit off under program control.
All audio connectors are gold plated to prevent corrosion and five types of wire
terminations can connect to the audio outputs. Highly efficient twin toroid
transformers provide ample power to eight two-channel amplifier modules. The eight
modules are of Crestron Detachable Modular Component (CDMC) design that
allows rapid field repair. Each channel (two per module) of each module has its own
power supply and filter capacitors that produce over 108,000 microFarads for
enhanced dynamic range. The heat sinks of each channel contain more than 300
square inches of radiating surface allowing cooler operation. No fans are required but
the unit must have a minimum of one rack space above and below for adequate
ventilation.
Physical Description
The CNAMPX-16X60, shown on the next page, is housed in a black enclosure with
silk-screened labels on the front and rear panels. The enclosure consists of 13-gauge
powder-coated steel with stainless steel screws. The front panel contains the main
power switch and light-emitting diode (LED). All audio input and output, Cresnet,
and power connections are made on the rear panel. There are four rubber feet on the
base of the unit for stability and to prevent slippage and two mounting ears with
screws are provided for rack mounting.

General Safety Precautions
Read all information and instructions provided in this operations guide.
Retain this operations guide.
Heed all warnings and cautions printed in this operations guide.
Follow all instructions in the order that they are provided.
Do not use this unit near water.
Clean only with a damp cloth.
Do not block any of the ventilation openings. Install in accordance with the
instructions in this operations guide.
Do not install near any heat sources such as radiators, heat registers, stoves, or
other apparatus that produce heat. If installing multiple CNAMPX-16X60s,
follow the instructions provided in this operations guide.
Do not defeat the safety purpose of the polarized or ground-type plug. A
polarized plug has two blades with one wider that the other. A grounding type
plug has two blades and a third grounding prong. The wide blade or the third
prong is provided for your safety. When the provided plug does not fit into an
outlet, consult an electrician for replacement of the obsolete outlet.
Protect the power cord from being walked on or pinched particularly at plugs,
convenience receptacles (if provided), and the point where they exit from the
unit.
Use only attachments/accessories specified in this operations guide.
When an equipment rack is used, use caution when moving the rack/unit
combination to avoid injury or tip-over.
Unplug this unit during lighting storms or when unused for long periods of time.
Refer all service to certified Crestron service personnel. Servicing is required
when the unit has been damaged in a way, such as power cord or plug is
damaged, liquid has been spilled or objects have fallen into the unit, the unit has
been exposed to rain or moisture, does not operate normally, or has been
dropped.
CNAMPX-16X60 Rear Ports and Indicators
A number of ports and indicators are provided on the rear of the 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.
