IDENTIFICATION OF CONTROLS
REAR PANEL
6 RS-232: Connect this interface via RS-232 serial cable (not supplied)
to any Windows® compatible PC to allow remote control of the T 175
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.
7 +12 V TRIGGER OUT: There are three configurable +12V TRIGGER
OUTPUT. Use a 3.5mm mini-jack connector to pass +12 volts at a
maximum current of 50 milliamps to auxiliary equipment such as a
multichannel amplifier or subwoofer. The centre conductor (hot) of the
3.5mm jack is the control signal. The outside conductor (shield) is the
ground return-path.
TRIGGER IN accepts 12V Trigger output of compatible components
such as power controllers and home automation devices.
TRIGGER OFF/AUTO : When at AUTO position, the T 175 selects the
12V Trigger Input to turn ON (if so assigned at the "TRIGGER SETUP"
menu) and at the same time disables the HTRC 1 and front panel's ON/
OFF function. When set to [OFF] position, the trigger input is disabled.
See discussion on "TRIGGER SETUP" at the "SETUP MENU" literature for
guidelines on how to configure TRIGGER IN/OUT.
WARNING
If Auto Trigger IN at Trigger Setup menu is assigned to "Main" or "All" and
the TRIGGER switch is set to "AUTO" mode, the Power button in the front
panel as well as the corresponding ON/OFF function keys in the HTRC 1
remote control will be disabled effectively handing this function to an
external controller. Switch TRIGGER to "OFF" to maintain normal power
ON/OFF function procedures.
8 IR IN/OUT: 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 175 from a remote location.
IR OUT 2 : When connected to the IR IN of an ancillary equipment,
direct the ancillary equipment's own remote control to the T 175's
infrared receiver to command or control the linked unit.
IR IN and IR OUT 3 : Connect the T 175's IR IN to the IR OUT of an
ancillary equipment. Connect also the T 175's IR OUT 3 to another
equipment with IR IN feature. With this setup, the T 175 acts as an "IR-
repeater" allowing the equipment connected to the T 175' s IR IN control
or command of the other equipment linked to the T 175's IR OUT 3.
IR OUT 1 : In conjunction with IR IN, IR OUT 1 can be used as an "IR-
repeater" just like the IR OUT 3 as described above. It can also stand
alone as an IR OUT similar to that of IR OUT 2 function.
All NAD products with IR IN/IR OUT features are fully compatible with
the T 175. For non-NAD models, please check with your other product's
service specialists as to their compatibility to the T 175's IR features.

9 AUDIO 1 IN/VIDEO 1 IN, AUDIO 2 IN/VIDEO 2 IN, AUDIO 3
IN/VIDEO 3 IN, AUDIO 4 IN/VIDEO 4 IN, AUDIO 5 IN/VIDEO 5 IN,
AUDIO 6 IN : These comprise the T 175's principal input. Connect
S-Video, composite video, and analog stereo audio from source
components such as DVD players and HDTV/satellite tuners.
AUDIO 3 IN/VIDEO 3 IN, AUDIO 4 IN/VIDEO 4 IN may be used with
recording components such as videocassette or DVD-recorders by
connecting these components' record-inputs to the corresponding
T 175 AUDIO 3 IN/VIDEO 3 IN or AUDIO 4 IN/VIDEO 4 IN jacks. AUDIO
3 IN/VIDEO 3 IN or AUDIO 4 IN/VIDEO 4 IN may freely be used for
play-only components, in which case their OUT jacks would remain
unconnected. Refer also to AUDIO 3 OUT/VIDEO 3 OUT, AUDIO 4 OUT/
VIDEO 4 OUT discussion below.
AUDIO 6 IN is advisable to connect to dedicated analog output from
line-level audio sources like a CD player or Stereo tuner.
10 MONITOR (S-VIDEO, VIDEO): Connect to video input of the monitor/
television using quality dual-RCA and/or S-Video cables designed for
video signals. In general, the S-Video connection is superior and should
be used if your TV/monitor provides the corresponding input.
11 AUDIO 3 OUT/VIDEO 3 OUT, AUDIO 4 OUT/VIDEO 4 OUT: Connect
the T 175's AUDIO 3 OUT/VIDEO 3 OUT or AUDIO 4 OUT/VIDEO 4 OUT
jacks to the analog audio/video input of a recording component
such as a cassette deck, DVD recorder or to an outboard audio/video
processor. Connect the T 175's AUDIO 3 IN/VIDEO 3 IN or AUDIO 4
IN/VIDEO 4 IN jacks to the component's corresponding output.
The signal present at these T 175 AUDIO/VIDEO OUT jacks is determined
by the source last selected via the front panel Source keys or the
HTRC 1's input select keys with the exception of Source 3 or Source
4. There will be no output when Source 3 (Audio 3 IN/Video 3 IN)
or Source 4 (Audio 4 IN/Video 4 in) is the selected source input.
This prevents feedback through the recording component thereby
preventing possible damage to your speakers.
When configured, AUDIO 3 OUT/VIDEO 3 OUT and AUDIO 4 OUT/VIDEO
4 OUT are the same assigned ports for Zone 3 and Zone 4 respectively.
See also Zone output description below.
12 ZONE 2, ZONE 3, ZONE 4: Sends zone selected audio and video output
sources to the corresponding audio and video input of another separate
zone. Use high quality patch cables to reduce noise pickup over long
distance runs. For a better understanding of zone settings, study below
the section on "ZONE CONTROLS" of the "MAIN MENU" discussion as well
as the item on "ZONE SETUP" under the "SETUP MENU" literatures.
NOTE
The ZR 4 remote control will only control Zone 2 applications. Zone 3
and Zone 4 could be configured and managed at the appropriate Zone
OSD menu using the front panel navigations buttons as well as the
corresponding keys on the HTRC 1 remote control.
