nad m25The NAD M25 7 channel audio amplifier is actually made up of seven individual mono block amplifiers with each channel using a balanced junction FET input stage to eliminate cross-talk, resulting in exceptionally low levels of noise and distortion. Additionally, NAD employs a unique electronic ground isolation circuit to prevent ground loop noise in the system-a common problem with many complex multi-channel systems.

M25 7-Channel Amplifier Features

  • 7 X 160 watts Full Disclosure Power, 20Hz – 20kHz, at less than 0.03THD with all channels driven simultaneously into 8/4 Ohms
  • Dynamic power of 220 watts at 8 Ohms, 385 watts at 4 Ohms, and 485 watts at 2 Ohms
  • NAD’s Custom-Made “Holmgren” transformer
  • Precision low noise Input Level Controls
  • 12V Trigger for advanced control options, 1 in
  • Detachable AC cord
