6. AUDIO PRE-OUTS / SUBWOOFER OUT

AUDIO PRE-OUTS - 

The NAD T74

2

receiver has five power amplifiers

built-in to power all the speakers connected to it (Left, Right, Centr

e

, Left

Surround, Right Surround). It is also possible to use the T74

2

 as a pre-

amplifier to drive external power amplifiers. This way, you use all the
control functions the T74

2

 provides, such as input select, surround

mode, volume, tone controls, etc., but the external power amplifier
actually powers the speaker connected to it instead of the T74

2

’s

integrated power amplifier for that channel.

Connect the RCA-to-RCA leads from the Front left and Right, Centr

e

,

and/or Surround Left and Right Audio pre-out connectors to the external
amplifiers. Connect speakers to the external amplifiers.

NOTES

• Never connect the T74

2

’s speaker outputs and the speaker outputs

of an external amplifier to the same speakers. When headphones are
inserted the signals from all audio pre-out outputs will be muted.

• Before making any connections, check that the T74

2

 and the power

amplifiers it will be connected to are switched off. With volume
turned down to a low level, switch power on only after all
connections have been made.

SUBWOOFER OUT - 

Unlike for the full range five channels as described

above, there is no power amplifier built-in for an additional subwoofer.
The Subwoofer pre-out allows for connection to a sub-bass speaker
system with its own external or integrated power amplifier (“active”
subwoofers).

7. MONITOR OUT 

Composite Video and S-Video outputs for connecting a TV or Video
Monitor to view video sources connected to 

DVD

 to VIDEO 5. Usi

V

ideo RCA-to-RCA lead, connect the “Video Line In” on the TV or

monitor to the MONITOR OUT.

Note that an S-Video signal will also be available as a Video Composite
signal on Monitor out, if the corresponding source is selected. The
composite video input signals (No. 4; yellow sockets) will also be available
as S-Video signal on the Monitor Out socket. If you use both S-Video and
Video composite sources, you will only need to connect the S-Video
Monitor Out to the television or projector. 

8. SPEAKERS: FRONT, CENTER & SURROUND SPEAKERS 

FRONT SPEAKERS -

Connect the right speaker to the terminals marked

‘FR’ ensuring that the red terminal is connected to the ‘+’ terminal on
your loudspeaker and the black terminal is connected to the
loudspeaker’s ‘-’ terminal. Connect the terminals marked “FL” to the left
speaker in the same way.

Always use heavy duty (16 gauge; 1.5mm or thicker) stranded wire to
connect loudspeakers to your T74

2

. Unscrew the speaker terminal’s

plastic bushing. Insert the bare cable end into the hole of the terminal and
then secure the cable by tightening down the terminal’s bushing (Fig. 6).

To avoid any danger of bare metal from the speaker cables touching the
back panel or another connector, ensure that there is only 1/2” (1.27cm)
of bare cable and no loose strands of speaker wire.

NOTE

This unit is designed to produce optimum sound quality when
speakers with impedance within the set’s ranges are connected.
Please check the following information and choose speakers with the
correct impedance for the connections.

FRONT SPEAKERS A: 8 ohms min. per speaker;

CENTER SPEAKER B: 8 ohms min.

SURROUND SPEAKERS: 8 ohms min. per speaker

CENTER SPEAKER - 

The terminal marked ‘C’ connects to the centr

e

loudspeaker that is used when the T74

2

 is operated in Dolby* Digital,

DTS, Dolby Pro Logic, EARS surround sound mode or with the 5.1 Ch.
input selected.

Connect the cent

re

 speaker in the same way as described with front

speakers above.

SURROUND SPEAKERS - 

This connects the Surround loudspeakers that

are used when the T74

2

 is operated in Dolby Digital, DTS, Dolby Pro

Logic, EARS Surround sound modes or with the 5.1 Ch. input selected.

Connect the surround speakers in the same way as described with
FRONT SPEAKERS above; connect the left surround speaker to the set of
terminals marked ‘SL’ and the right surround speaker to the  terminals
marked ‘SR’. 

NOTE

The Cent

re

 and/or Surround speakers must be selected as Large or

Small in the Set-up menu “SPK SET” when speakers are connected to
these outputs.

9. SOFT CLIPPING 

When any amplifier is driven beyond it’s power output capabilities, a
hard, distorted sound can be heard on very loud sounds. This is caused
by the amplifier cutting off or ‘hard clipping’ the peaks of sound that it
was not designed to reproduce. The NAD Soft Clipping circuit gently
limits the output of the system to minimize audible distortion if the
amplifier is overdriven. 

If your listening involves moderate power levels you may leave the Soft
Clipping switch off. If you are likely to play at high levels that exceed the
amplifier’s power capability, then switch Soft Clipping on.
