Crestron CNAMPX-16X60 16-Channel Amplifier

Description

The Crestron CNAMPX-16X60 is a substantial, professionally engineered multi-room power amplifier designed for high-performance distributed audio systems. Built for custom residential and commercial installations, it combines sixteen channels of Class AB amplification with Crestron’s sophisticated control and monitoring capabilities. Although originally intended primarily for integration into Crestron whole-house audio systems, its considerable power reserves, robust construction, and carefully engineered amplifier modules make it an interesting component for anyone exploring high-quality multi-zone audio equipment.

At the heart of the CNAMPX-16X60 is a sixteen-channel architecture arranged as eight independent stereo amplifier pairs. Each channel delivers a continuous 60 watts into 8-ohm speakers, with output increasing to 90 watts into 4-ohm loads. This allows the amplifier to accommodate a wide variety of architectural and conventional loudspeakers. For applications requiring additional power, selected channel pairs can be bridged using Crestron’s optional CNXBRMO bridging interface, producing up to 220 watts into 8 ohms.

The amplifier employs a high-performance Class AB circuit incorporating discrete, high-current bipolar output transistors. Its power supply is particularly impressive, utilizing two substantial toroidal transformers with MOH cores and bifilar windings. Each stereo amplifier module receives its own dedicated power supply arrangement, helping maintain consistent performance when multiple rooms are operating simultaneously. This design emphasizes current delivery, dynamic stability, and reliable operation under demanding multi-channel conditions.

Sound quality was clearly an important consideration in the amplifier’s development. Crestron specifies total harmonic distortion of 0.03% or less at full power, a signal-to-noise ratio exceeding 110dB, and channel separation greater than 100dB. Frequency response is exceptionally flat, measuring within +0/-0.1dB from 20Hz to 20kHz at one watt. These specifications suggest an amplifier designed to reproduce music with low coloration, excellent channel isolation, and sufficient dynamic capability for everyday listening throughout a home.

One of the CNAMPX-16X60’s most interesting characteristics is its integration with Crestron’s Cresnet control network. When connected to a compatible control system, individual stereo zones can be switched on and off remotely. The amplifier also monitors operating temperature, output conditions, and electrical faults, allowing the control system to identify potential problems before they become serious. Opto-coupled output protection and inrush-current limiting further contribute to dependable operation.

The physical construction reflects the amplifier’s professional orientation. Its heavy-duty steel chassis occupies four rack spaces and weighs approximately 90 pounds. Eight detachable amplifier modules simplify servicing, while extensive heatsinking provides more than 300 square inches of cooling surface per stereo module. The convection-cooled design eliminates the need for internal cooling fans, although Crestron recommends leaving adequate ventilation space above and below the unit.

For installation purposes, the CNAMPX-16X60 provides eight stereo RCA inputs and sixteen five-way speaker binding posts. It is particularly well suited to installations using Crestron’s PAD8 audio distribution processors, although the amplifier’s conventional analog inputs offer some flexibility when incorporating it into other audio systems. Its substantial size, weight, and specialized control architecture should be considered before attempting to use it as a conventional stereo amplifier.

Originally positioned as a premium distributed-audio component, the Crestron CNAMPX-16X60 remains an impressive example of serious multi-channel amplifier engineering. Its combination of substantial power supplies, discrete Class AB circuitry, excellent measured specifications, and comprehensive protection makes it a compelling choice for appropriately configured whole-house audio installations. Although discontinued, it remains an interesting option on the used market, particularly for buyers seeking a robust sixteen-channel amplification platform.
