DISC

: Connect the analog stereo audio output from a second CD player or other line-level audio source to this input.

NOTE

: Connecting a phonograph turntable to the T 752 requires an outboard magnetic phono-preamp component such as the NAD PP1; you

cannot connect turntable directly to the DISC inputs.

6

IR

: These mini-jacks accept and output remote-control codes in electrical format, using industry-standard protocols, for use with “IR-repeater”

and multi-room systems and related technologies. Consult your NAD audio specialist for more information.

7

COMPONENT VIDEO IN 1/2; OUT

: Connect the COMPONENT VIDEO IN 1 AND 2 inputs to component-video outputs from compatible source

components, typically a DVD player and terrestrial or satellite HDTV tuner. Connect the T 752 COMPONENT VIDEO OUT to the component-video
input of a compatible video monitor/TV. Be sure to observe consistency in connecting the Y/Cr/Cb jacks (some source and TV components label
these Y/Pb/Pr) to the corresponding sources/inputs; do not rely purely on the color-coding of the jacks, which may not always be consistent among
brands. The routing of the component-video inputs is fixed: COMPONENT VIDEO IN 1 is routed to the COMPONENT VIDEO OUT jacks when the
DVD input is selected; COMPONENT VIDEO IN 2 is selected when the SAT input is active; the audio and digital inputs assigned to DVD and SAT
will be used (see also, "Source Setup," below).

NOTE

: The T 752’s component-video inputs and outputs are fully wide-band, compatible with all HDTV formats. The T 752 does not display its

on-screen menus on its component-video output. To use on-screen menus, you will need to make an S-Video or composite connection between
the T 752 and the monitor/TV, and select it for menu display.

8

SOFT CLIPPING

: Enables NAD’s proprietary Soft Clipping circuitry on all channels. Soft Clipping gently limits the output of the T 752 to minimize

audible distortion, even should the receiver be over-driven.

NOTE

: Soft Clipping may simply be left on at all times to reduce the likelihood of audible distortion from excessive volume settings. However, for

critical listening, to preserve optimum dynamics you may wish to defeat it by setting this switch off.

9

SWITCHED AC OUTLET

: This convenience jack can supply switched power to another component or accessory. It is powered on and off by the

front panel POWER key (or the HTR2’s [On] and [Off] keys).

NOTE

: The total draw of all devices connected to this jack must not exceed 120 watts.

10

AC POWER INLET

: Connect to the supplied IEC-standard removable AC power cord or a compatible cord.

11

DIGITAL IN OPT 1-2; COAX3-6

: Connect to the coaxial S/PDIF-format digital outputs of sources such as CD or DVD players, HDTV or satellite

tuners, or other components; connect DIGITAL IN OPT1-2 to optical S/PDIF-format digital outputs.

DIGTAL OUT

: Connect the optical and/or coaxial DIGITAL OUT ports to the corresponding S/PDIF digital input of a recording component such as

a CD recorder, DAT deck, or computer soundcard. See "Source Setup", below.

12 SPEAKERS

: Connect the left and right front, center, and left and right surround speaker outputs to the corresponding loudspeakers. Each output’s

“+” (red) terminal and “-” (black) terminal must be connected to the corresponding “+” and “-” terminals of the loudspeaker. Use extra care to
ensure that no stray wires or strands cross between posts or terminals at either end.

NOTE

: Use stranded wire of at least 16 gauge (AWG); specialized speaker cable may be valuable (consult your NAD audio specialist). Connections

to the T 752 can be made with banana-type plugs, or using bare wire, or pins, by loosening the terminal’s plastic nut, making a clean, neat
connection, and re-tightening carefully (use the transverse hole through the post for bare-wire or pin connections). To minimize the danger of
short-circuits, ensure that only 1/2-inch of exposed wire or pin is employed in connecting.

NOTE

: This unit is designed to produce optimum sound quality when connected to speakers with impedances within the receiver’s operating

range. Please check front, center, and surround speakers are rated to be 4

 min. per speaker.

IMPORTANT NOTE

: For optimum surround performance, the T 752 speaker settings and levels must be set correctly via the receiver’s setup

routines; see “Setting Up the T 752”, below.

13 12V TRIGGER IN/OUT:

TRIGGER IN

 connects to the 12-volt trigger outputs of compatible components such as power controllers and home automation devices.  The

TRIGGER AUTO/OFF switch selects the 12V Trigger Input and disables the remote and front panel ON function.

TRIGGER OUT

 connects to 12V Input of compatible devices (such as amplifiers and projector-lifts) to automate turn on/off or activation.  See

“Trigger Setup”, below your NAD audio specialist also can provide more information on using the T 752’s triggers.

14 DVD, SAT, VCR, VIDEO 4, VIDEO 5

: These comprise the T 752’s principal inputs. Connect S-Video, composite video, and analog stereo audio from

source components such as DVD players and HDTV/satellite tuners (see "Source Setup," below). VCR and VIDEO 4 may be used with recording
components such as videocassette or DVD-recorders; connect the T 752 S-Video/composite video OUT jacks to these components’ record-inputs.
(Note that VCR/VIDEO 4 may freely be used for play-only components, in which case their OUT jacks would remain unconnected.)

15

TAPE IN/OUT

: Connect the T 752’s TAPE OUT jacks to the stereo analog audio inputs, of an audio recording component such as a cassette deck

or CD recorder, or of an outboard analog audio processor such as a stereo equalizer; connect the receiver’s TAPE IN jacks to the component’s
corresponding outputs. The signals present at the TAPE IN jacks can be heard by selecting the front panel TAPE MONITOR button, or the HTR 2’s
[Tape] (zero) key.

NOTE

: The signal present at the TAPE OUT jacks is determined by the source last selected via the front panel Video or Audio keys (or the HTR

2’s input-select keys).

NOTE

: Digital input signals are not available at the analog TAPE OUT jacks; they are only available at the DIGITAL OUT jacks.

16 7.1 CH. INPUT

: Connect to the corresponding analog audio outputs of a multichannel source component such as a DVD-Audio or multichannel-

SACD player, or external multichannel decoder. Typically, these sources will produce 5.1-channel output, in which case the SURROUND BACK jacks
are left unconnected. The signals present at these jacks may be heard by selecting the front-panel EXT. 7.1 key or the HTR 2’s [Ext 7.1/5.1]
button. See “Selecting Sources," below.

NOTE:

 There is no bass-management or other processing (other than master-volume control) available to this 7.1 CH. INPUT.  While the multi-

channel audio outputs of a DVD-Video player can be connected to these jacks, using the T 752’s own Dolby Digital and DTS decoding and digital-
analog converters, via a digital connection, will usually produce superior results.
