4. Speaker Connections

This amplifier is equipped with special high-current

binding-post speaker terminals. Connect the loud-

speakers with heavy-duty (16-gauge or thicker)

braided wire. Connections may be made in either of

two ways. [See Figure 1.*]

(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 binding

post, and tighten the knob until it grasps the wire se-

curely. Check to be sure that there are no loose strands

of wire 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 ter-

minals are separated by

accept dual-banana plugs.*

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 red (positive) ter-

minal on the amplifier.

5. 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 lim-

its 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 925THX be left in the ON posi-

tion when system is being operated at levels that might

exceed the amplifier's power capacity.
