Reference 7-channel home cinema power amplifier • Purifi Eigentakt™ Class D amplifier technology • 200W continuous per channel into 8Ω (all 7 channels driven) • 340W continuous per channel into 4Ω • balanced XLR & unbalanced RCA inputs • Masters Series aluminum casework with magnetic iso-point feet
The NAD M28 7-Channel Power Amplifier represents the absolute benchmark in multi-channel reference amplification, engineered to deliver reference cinema dynamics and studio-grade transparency across all seven surround channels. Built with state-of-the-art Purifi Eigentakt™ Class D amplifier modules, the M28 generates 200 watts continuous power per channel into 8 ohms and 340 watts into 4 ohms with all channels driven simultaneously, eliminating crossover distortion, harmonic coloration, and load sensitivity across the entire audible spectrum. Encased in NAD’s signature Masters Series heavy-gauge extruded aluminum chassis with custom magnetic isolation footers, it delivers immense transient speed, effortless high-current headroom, and silent backgrounds for high-performance Dolby Atmos and DTS:X cinema installations.
Key Features & Innovations
State-of-the-Art Purifi Eigentakt™ Amplification — the NAD M28 7-Channel Power Amplifier deploys Purifi's self-oscillating Class D architecture to virtually eradicate intermodulation distortion and magnetic hysteresis, resulting in an inaudible noise floor and pure, natural sonic fidelity even when driving complex, low-impedance loudspeaker loads.
Full Rated Output Across All Seven Channels Driven — delivers 200W continuous per channel into 8 ohms and 340W continuous into 4 ohms across all seven channels simultaneously, backed by dynamic power reserves reaching 560W per channel into 4 ohms to reproduce demanding Hollywood cinematic peaks without compression.
Balanced XLR and Single-Ended RCA Inputs — features seven individual gold-plated balanced XLR inputs and locking single-ended RCA terminals with dedicated rear-panel selector switches, ensuring an optimal, noise-free interface with flagship AV processors.
Load-Invariant Acoustic Linearity — unlike conventional switching amplifiers whose frequency response varies depending on speaker impedance, Eigentakt circuitry ensures an entirely flat, unvarying frequency response regardless of individual speaker impedance curves.
Masters Series Thermal & Mechanical Architecture — housed in a precision-milled aluminum casework designed for passive convective cooling with near-zero heat waste, anchored by magnetic iso-point decoupling feet that isolate internal electronics from mechanical room resonances.
FAQ — NAD M28
Does the NAD M28 7-Channel Power Amplifier maintain its full rated power with all 7 channels driven simultaneously?
Yes. The NAD M28 7-Channel Power Amplifier delivers a full continuous 200 Watts RMS per channel into 8 Ohms and 340 Watts RMS per channel into 4 Ohms across all seven discrete channels operating simultaneously, without current limiting or power supply sag.
Can this amplifier drive low-impedance 4-ohm home theater speakers without overheating?
Yes. Purifi Eigentakt technology operates at ultra-high efficiency with minimal thermal waste, allowing the M28 to effortlessly deliver sustained high-current drive into 4-ohm and even 2-ohm impedance loads without triggering thermal protection or running hot.
Does the amplifier support automated 12V trigger power control?
Yes. The rear panel includes a 12V trigger input and pass-through output, allowing your AV processor or preamplifier to automatically power the M28 on and off in synchronized sequence with your home cinema system.
Can I mix balanced XLR and RCA connections across different channels?
Yes. Each of the seven channels features an independent toggle switch on the rear panel to select between its balanced XLR and single-ended RCA input, offering total flexibility to match processor outputs.
