I have a "used" Crestron CNAMPX-7x200 that came from a working system. Please take a look at the pictures provided as there is some cosmetic damage to the item. You are getting the amplifier that is displayed in the pictures.The one rack ear is slightly bent but is still functional. This does call for a 20 amp circuit.
I don't know if this amp has auto sensing inputs but I don't see any 12v trigger on the back. Please do some of your own research before purchase if you don't currently have a Crestron system.
The amp will be shipped via FedEx Home delivery and will need to be signed for upon delivery. Comes with shipping insurance. Check my feedback as I have sold many stereo/surround sound receivers and amplifiers with great success. Buy with confidence.
Description of the amplifier:
The CNAMPX-7X200 provides 7 channels of world-class audio
amplification as part of a complete Crestron Home® theater system.
Brilliantly designed to complement Crestron's DAP8 7.1 surround
sound processors, the CNAMPX-7X200 delivers a vigorous 200 watts per
channel into 8 ohms, and 300 watts per channel into 4 ohms.
Its massive twin toroidal power transformers feature MOH cores for
maximum efficiency, with bifilar windings directing pure, continuous
power to each of the seven mono amplifier channel modules. Each
channel module includes its own power supply fed by a separate set of
transformer windings, producing astounding dynamic range and very low
distortion from every channel, all the time.
The highest grade components mounted to multi-layer FR-4 glass epoxy
circuit boards help guaranty a long life of trouble free operation.
With more than 300 square inches of heat sink surface area per
channel, cool, quiet, and reliable operation is ensured. Gentle
power-up is achieved through a "soft-start" inrush current limiting
circuit. Quick-response opto-coupled output protection on each channel
prevents failures caused by speaker line faults or signal spikes,
providing exceptional dependability with no compromise to sound
quality. In the unlikely case of a failure, Crestron's Detachable
Modular Component design allows for rapid repair in the field.
Its interface to the Cresnet control network affords remote power
control and monitoring of the internal temperature. Over-temperature
conditions can be sensed by the control system and used to display a
warning message on a touchpanel, reduce audio levels, or even activate
an external cooling fan.
