mode or with low-impedance loudspeakers. Connect the loudspeakers with heavy-duty (16-gauge or thick- er) stranded wire.

Connections may be made in either of two ways. [See Figure 2.]

(1)Strip off a half-inch (1 cm) of insulation from each speaker wire. In each conductor, twist the thin strands of wire together. Unscrew the knob, insert the bare wire into the opening at the base of the bind- ing post, and tighten the knob until it grasps the wire securely. Check to be sure that no loose strand of wire is touching the chassis or an adjacent terminal.

(2)Install banana plugs on your speaker wires, and plug them into the end of each binding post. The terminals are separated by 3/4 inch (19mm), so they will accept dual-banana plugs.

Connect the wires from the left-channel speaker to the CH 1 + and CH 1 - terminals and the wires from the right-channel speaker to the CH 2 + and CH 2 - terminals.

NOTE — Stereo speakers must operate in phase with each other in order to produce a focused 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 red (positive) terminal on the amplifier.

6. BRIDGING

The two amplifiers within the Model 912 can be “bridged” to form a single amplifier of about three times the power per channel.

To convert to bridged operation:

(1)Switch the POWER off.

(2)Disconnect any input and output cables.

(3)Set the bridging switch to ON.

(4)Select the cable from the speaker that is to be driven by the 912. Connect its “positive” conductor to the CH 1 + terminal and its “negative” conductor to the CH 2 + terminal (i.e. to the two red terminals). DO NOT connect any wires to the black terminals (CH 1 - and CH 2 -).

CAUTION: In the bridged mode, wires must be connected directly from the amplifier to the speakers, not to a speaker switch, headphone adapter, or any other device that shares a common ground between channels.

(5)Connect the signal lead from the source chosen to be amplified by the bridging amplifier to the input socket of the CH 1 amplifier.

(6)Turn the POWER on.

NOTE — If you are using two pairs of speakers on one channel, or if you are in the bridged mode, we recommend that the speakers have a nominal imped- ance of 8 or more.

7. 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 output transistors saturate. The NAD

GB

SOFT CLIPPING circuit gently limits the output wave- form and minimizes audible distortion when the amplifier is overdriven. We recommend that it be switched ON when playing music at levels that might exceed the amplifier’s power capacity.
