16 Channel Professional Audio
Amplifier: CNAMPX-16X60
Description
Functional Description
The CNAMPX-16X60 is a Crestron control network (Cresnet ) 16 channel, 60Watts 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.

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.

16 Channel Professional Audio Amplifier |
Crestron CNAMPX-16X60 |
PWR Indicator
This LED (green) is illuminated when operating power is supplied to the CNAMPX16X60.
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 CNAMPX16X60. 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 preamplified 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 goldplated 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.
