NAD T 747 Owner's Manual page 9

8 7.1 CH INPUT: Connect to the corresponding analog audio output
ports of multichannel source components such as a DVD-Audio or
multichannel-SACD player or external multichannel decoder (disc copy
protected formats only allow analog signal transfer). 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 Multi (7.1 Channel Input is defaulted to this
Source setting).
There is no bass-management or other processing (other than master-
volume control) available to this 7.1 Channel Input. While the multi-
channel audio outputs of a DVD-Video player can be connected to
these jacks, using the T 747's own Dolby Digital and DTS decoding and
digital-analog converters via a digital connection will usually produce
superior results.
9 AUDIO PRE-OUT: The Audio PRE- OUT makes it possible to use the
T 747 as a pre-amplifier to external power amplifiers for some or all
channels. Connect FRONT L, FRONT R, CENTER, SURR R, SURR L, SURR-BL
and SURR-BR to the respective channel input of a power amplifier or an
amplifier driving the applicable speakers.
Unlike the full range channels, there is no power amplifier built-into the
T 747 for a subwoofer. Connect the SUBW output to powered ("active")
subwoofers or to power amplifier channels driving a passive system.
10 FM, AM ANTENNA INPUT: Connect the supplied lead-type FM
antenna to the FM antenna input. Extend the lead. Experiment freely
with your antenna placement and orientation until you get the clearest
sound and lowest background noise. Fix the antenna in the desired
position by using thumb tacks, push pins or any suitable means.
The AM loop antenna supplied with the T 747 (or a suitable
replacement) is required for AM reception. Open the clip terminal
lever; insert the wire making sure to match the color-coded (white
and black) ends of the wire to that of the terminal and close the
lever ensuring that the lever locks the wire in place. Testing different
positions for the antenna may improve reception; vertical orientation
will usually produce the best results. Antenna proximity to large metal
objects (appliances, radiators) may impair reception, as will attempts to
lengthen the wire to the loop.
Refer also to the "LISTENING TO AM/FMRADIO" segment of the
"OPERATION - LISTENING TO AM/FM/XM RADIO" section.
11 XM MODULE INPUT (120V version only): Connect XM radio cable
to this socket. Follow the instructions that came with your XM radio.
With XM radio, there are more than 100 channels of music, news, sports,
comedy, talk and entertainment. You will find that the coverage is
continent wide. The music quality is digital with many commercial-free
music channels. Refer also to the "LISTENING TO XM RADIO" segment of
the "OPERATION - LISTENING TO AM/FM/XM RADIO" section.
NOTE
The external XM radio is not supplied with your T 747.
12 UPLOAD (MCU, HDMI), RESET: The MCU, HDMI and RESET tact
switches are used for software program updates (if any) in combination
with the RS232. Your custom installer or dealer can assist you in the
proper upgrade and setup of your T747.
IDENTIFICATION OF CONTROLS
13 IR IN/IR OUT 1-2: These mini-jacks accept and output remote-
controlled codes in electrical format, using industry-standard protocols,
for use with "IR-repeater" and multi-room systems and related
technologies.
IR IN: This input is connected to the output of an IR (infrared) repeater
(Xantech or similar) or the IR output of another component to allow
control of the T 747 from a remote location.
IR OUT 1, IR OUT 2: Both IR OUT 1 and IR OUT 2 have dual-features –
they can act as an infrared command repeater or stand alone as IR OUT.
Connect the T 747's IR IN to the IR OUT of ancillary equipment. Connect
also the T 747's IR OUT 1 (or IR OUT 2) to another equipment with IR IN
feature. With this setup, the T 747 acts as an "IR-repeater" allowing the
equipment connected to the T 747' s IR IN control or command of the
other equipment linked to the T 747's IR OUT 1 (or IR OUT 2).
As a stand alone IR OUT, connect IR OUT 1 (or IR OUT 2) to the IR IN of an
ancillary equipment. Direct the ancillary equipment' s own remote control
to the T 747' s infrared receiver to command or control the linked unit.
14 +12V TRIGGER OUT: The +12V TRIGGER OUT is used for controlling
external equipment that is equipped with a +12V trigger input. Connect
this +12V TRIGGER OUT to the other equipment's corresponding
+12V DC input jack using a mono cable with 3.5mm male plug. The
availability of 12V at this trigger output depends upon the setting of
"Trigger Out" in the TRIGGER SETUP OSD menu. See discussion about
"TRIGGER SETUP" at the "SETUP MENU" literature for guidelines on how
to configure "Trigger Out".
15 MP DOCK: The T 747 is equipped with a data port in the rear panel
where an optional NAD IPD (NAD IPD Dock for iPod) 1, NAD IPD 2 and
later variants can be plugged in. Connect the "MP DOCK (DATA PORT)"
jack of the T 747 to the corresponding "DATA PORT" socket of the
optional NAD IPD model. Refer also to the "LISTENING TO YOUR iPod
PLAYER" segment of the "OPERATION" section.
NOTE
The external "NAD IPD (NAD IPD Dock for iPod)" model is not supplied
with your T 747.
16 DAB MODULE INPUT (230V version only): Plug-in the other end
of the Mini-Din connector from the NAD DAB Adaptor DB 1 module
output port into this socket. The T 747 is compatible only with NAD
DAB Adaptor DB 1 so check with your NAD dealer for this module's
availability. With DAB, you can receive CD-like quality programs without
any annoying interference and signal distortion. Refer also to the
"LISTENING TO DAB RADIO" segment of the "OPERATION" section.
NOTE
The external "NAD DAB Adaptor DB 1 module" is not supplied with your
T 747.
17 RS-232: Connect this interface via RS-232 serial cable (not supplied)
to any Windows® compatible PC to allow remote control of the T 747
through NAD's proprietary PC software or other compatible external
controllers. NAD is a certified partner of AMX and Crestron and fully
supports these external devices. See your NAD audio specialist for more
information.
