13 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 785 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 785’s
infrared receiver to command or control the linked unit.
IR IN and IR OUT 3. Connect the T 785’s IR IN to the IR OUT of an
ancillary equipment. Connect also the T 785’s IR OUT 3 to another
equipment with IR IN feature. With this setup, the T 785 acts as an “IR-
repeater” allowing the equipment connected to the T 785’ s IR IN control
or command of the other equipment linked to the T 785’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 785. For non-NAD models, please check with your other product’s
service specialists as to their compatibility to the T 785’s IR features.
14 HDMI (HDMI 1-4, HDMI MONITOR OUT) : Connect HDMI inputs
to the HDMI OUT connectors of source components such as DVD/BD
player or HDTV satellite/cable box. Connect the HDMI Monitor OUT to a
HDTV or projector with HDMI input.
WARNING
Before connecting and disconnecting any HDMI cables, both the T 785
and the ancillary source must be powered OFF and unplugged from the
AC outlet. Failure to observe this practice may cause permanent damage
to all equipment connected via HDMI sockets.
15 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.
16 AUDIO PRE-OUT : The Audio PRE- OUT makes it possible to use the
T 785 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
amplifiers driving the corresponding applicable speakers.
Unlike the full range channels, there is no power amplifier built-into the
T 785 for a subwoofer. Connect the SUBW 1 or SUBW 2 output or both
to powered (“active”) subwoofers or to power amplifier channels driving
a passive system.
NOTE
Never connect both the external amplifier and T 785’s speaker outputs to
the same set of speakers.
17 SPEAKERS A, SPEAKERS B : Connect the respective SPEAKER A’s
FRONT L, FRONT R, CENTER, SURR R, SURR L, SURR-BL and SURR-BR
channels to their corresponding loudspeakers. Make sure the “+” (red)
terminal and “-“(black) terminal are 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.
Connect left and right channels of Speakers B to the corresponding
remote loudspeakers. When Speakers B is activated, the output is
converted to ‘Stereo Downmix’ as indicated in the VFD. Combining
Speaker A and Speaker B (SPEAKERS A + B) will also result to the source
being downmixed to stereo.
The T 785 is designed to produce optimum sound quality when
connected to speakers with impedances within its operating range.
Please make sure that all the speakers are rated 4Ω minimum per speaker.
NOTE
Use stranded wire of at least 16 gauge (AWG). Connections to the T 785
can be made with banana plugs (120V version only) or by using bare
wire or pins. Use the transverse hole through the post for bare-wire or
pin connections. By loosening the terminal’s plastic nut, make a clean,
neat connection and re-tighten carefully. To minimize the danger
of short-circuit, ensure that only 1/2-inch of exposed wire or pin is
employed when connecting.
18 AC MAINS INPUT: The T 785 comes supplied with a separate AC Mains
cable. Before connecting the cable to a live wall socket, ensure that it is
firmly connected to the T 785’s AC Mains input socket first. Connect only
to the prescribed AC Outlet, i.e., 120V 60 Hz (for 120V version models of
T 785 only) or 230V 50 Hz (for 230V version models T 785 only). Always
disconnect the AC Mains cable plug from the live wall socket first, before
disconnecting the cable from the T 785 Mains input socket.
19 SWITCHED AC OUTLET : This convenience outlet can supply switched
power to another component or accessory. With the POWER switch at
the rear panel set to ON position, this outlet is powered ON or OFF by
the front panel STANDBY switch or by the HTRC 1’s ON/OFF buttons.
The total draw of all devices connected to this jack must not exceed
120 watts.
20 POWER : The POWER switch supplies the master AC mains power for
the T 785. When this switch is at ON position, the T 785 is in standby
mode as shown by the amber status condition of the standby LED. If
you intend not to use the T 785 for long periods of time (such as when
on vacation), switch the POWER switch to the OFF position. When
the POWER switch is at OFF position, the front panel standby button,
HTRC 1 remote control or ZR 4 cannot activate the T 785.
