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.
