The M28 is a seven-channel power amplifier that combines Purifi Eigentakt amplification with NAD's HybridDigital architecture. Every channel is rated at 200 W into 8 ohms with all channels driven, and the amplifier has substantial dynamic headroom for sudden level changes in film and music. Noise and distortion are specified at very low levels, and the frequency response stays flat across varying speaker loads.
For connection to a processor it offers fully balanced XLR inputs as well as single-ended RCA inputs. Speakers attach through high-quality binding posts. The design is compact and energy-efficient with low heat output, so it can be placed in a dedicated rack or a custom installation.
Control integration downloads are listed for Control4, Crestron, Lutron, NICE, RTI and URC, along with RS232 documentation. Manuals are available in English, French, German and Spanish, plus a data sheet and quick start guide. The unit moves to standby automatically after up to 30 minutes without an input signal.
