NAD M28 Q&A:
What is the NAD M28 designed for?
The M28 is designed for high-end home theater and multichannel audio systems that need powerful, clean amplification across seven channels.
How much power does the M28 deliver per channel?
It delivers ≥ 200W per channel with all seven channels driven (8 ohms, 20 Hz–20 kHz), ensuring consistent output across the entire system.
Does the M28 support both balanced and unbalanced connections?
Yes. It includes balanced XLR inputs for long, noise-resistant runs and unbalanced RCA inputs for flexible system matching.
What makes Purifi Eigentakt™ important in this amplifier?
Purifi Eigentakt™ is known for extremely low distortion and high linearity, helping the M28 sound transparent, controlled, and natural even under heavy load.
Will the M28 work well with difficult speaker loads?
Yes. The M28 is designed to maintain a flat, stable response across varying speaker loads, keeping the sound consistent and tonally balanced.
Does it include automation features for custom installations?
Yes. A 12V trigger input allows the M28 to integrate with AV processors and control systems for automatic power on/off behavior.
How efficient is the amplifier in standby?
The M28 is rated at ≤ 0.5W standby power, and it can enter standby after ≤ 30 minutes with no input signal.
