NAD 906 Multi-Channel Power Amplifier

The 906 contains six very powerful amplifiers (three separate stereo amplifiers) inside a compact case. Built with the highest quality, high-temperature components and is fully capable of driving 4 ohm loudspeakers for long periods.


Features of the NAD 906 Multi-Channel Power Amplifier

INPUTS

Each of the three independent stereo power amplifiers within the 906 has its own pair of inputs and outputs. If you need fewer than six channels of amplification see BRIDGING.


LINE OUTPUTS

Each input has an accompanying line output which will pass the signal on to another amplifier input or other line-level device.

The line outputs are buffered, so that a low impedance or short circuit placed across it will not affect the signal at the input.

For multi-room installations the line outputs may be connected to the inputs of another pair of amplifiers within the 906 to provide separate stereo amplification for one or two other zones, each with its own level control.

 

INPUT LEVEL

The amplifier is equipped with separate input level controls for each channel.

Under some circumstances, the level controls may be useful for:

  1. Level-matching.
  2. Extended volume-control range.
  3. Balance correction.

 

SPEAKER CONNECTIONS

This amplifier is equipped with special high current binding-post speaker terminals to handle the highest peak power levels that may occur in the "bridged" mode or with low-impedance loudspeakers.

 

BRIDGING

Each pair of amplifiers with the Model 906 can be "bridged" to form a single amplifier of about three times the power per channel.

If you currently need fewer than six channels of amplifications, use this feature to increase the available amplifier power.

For example, bridging two for the 906's pairs of amplifiers will yield two mono amplifiers of 90W apiece for the main channels and one stereo amplifier of 30W per channel for a remote set of speakers.

 

SOFT CLIPPING

When an amplifier is driven beyond its specified power output it normally produces "hard clipping" of the signal with harsh distortion and power-supply buzz as the out transistors saturate.

The NAD SOFT CLIPPING circuit gently limits the output waveform and minimizes audible distortion when the amplifier is overdriven.
