Nad 310 stereo integrated amplifier

The NAD 310 has the basic front-panel controls: bass and treble tone adjustment (with a tone-defeat button) and large concentric volume knobs for the left and right speaker channels, which normally operate as a single control but can be set independently. The front panel also has a pushbutton power switch and two small LED indicators (green for power on, and red to show that the amplifier's protection circuit has been tripped by overheating or a short-circuit).

The amplifier has the same dark gray and black finish that has been a hallmark of NAD products since their inception. On the rear apron, in addition to the phono-jack inputs and outputs, are two pairs of multiway speaker-output binding posts that accept dual banana plugs as well as wire ends or spade lugs.
