NOTE: Speakers must operate in phase with each other in order to produce a proper stereo image and to reinforce rather than cancel each other’s output at low frequencies. When connecting speakers, take care that the red (positive) terminal on each loudspeaker is connected to the corresponding terminal marked red (positive) on the amplifier.
7. SOFT CLIPPING
When an amplifier is driven beyond its specified power output it normally produces “hard clipping” or distortion of the signal. Such hard clipping, in addition to sounding unpleasant, can damage the speakers in the system. The NAD Soft Clipping circuit gently limits the output waveform, minimizing audible distortion and reducing the change of speaker damage when the amplifier is overdriven. We recommend that the Soft Clipping switch on the back panel of the M25 be left in the ON position when system is being operated at levels that might exceed the amplifier’s power capacity. The LED on the front panel indicates if Soft Clipping has been engaged.

9. GROUND CONNECTOR
The M25 is provided with a GROUND terminal on the rear panel. This terminal is connected directly to the chassis of the M25. In the event of radio hum or radio interference, this terminal can be connected to a ‘true earth’ such as a copper plated rod driven several feet into the ground.
