CNAMPX-16X60

16 Channel Multi-Room Amplifier
Audiophile-grade 16 channel amplifier High-performance Class AB design Discrete high-current, bipolar output transistors

The CNAMPX-16X60 provides 16 channels of world-class audio amplification for the distribution of speaker-level audio to up to 8 stereo room zones as part of a complete Crestron Home audio distribution system. Brilliantly designed to complement Crestron's PAD8 audio distribution processors, the CNAMPX-16X60 delivers a robust 60 watts per channel into 8 ohms, and 90 watts per channel into 4 ohms. Through the use of the optional CNXBRMO bridging interface, up to eight of the CNAMPX-16X60's sixteen outputs may be bridged to produce 220 watts per channel into 8 ohms.

Its massive twin toroidal power transformers feature MOH cores for maximum efficiency, with bifilar windings directing pure, continuous power to each of the eight stereo amplifier modules. Each module includes its own power supply fed by a separate set of transformer windings, producing astounding dynamic range and very low distortion in every room, 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 stereo module, 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.

The CNAMPX-16X60 combines true audiophile performance with Crestron intelligence, allowing critical control and diagnostic information to be reported to the control system via the Cresnet control network. From the control system, the main amplifier power, as well as each stereo amp channel, can be individually turned on and off. Faults within any amp module or the connected speaker lines are detected and reported to the control system, and amplifier temperature and output levels can be monitored. This valuable diagnostic information can be used by the control system to display a warning message on a touchpanel, reduce audio levels, or even activate an external cooling fan.
