NAD T785 Owner's Manual page 11

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 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 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 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, SURR R, SURR L, SURR-BL,
SURR-BR and CENTER to the respective channel input of a power
amplifier or an amplifier 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.
IDENTIFICATION OF CONTROLS
17 SPEAKERS A, SPEAKERS B : Connect the respective SPEAKER A's
FRONT L, FRONT R, SURR R, SURR L, SURR-BL, SURR-BR and
CENTER 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 4 ohms minimum per
speaker.
NOTE
Use stranded wire of at least 16 gauge (AWG). Connections to the T 785
can be made with banana plugs (US model 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 POWER INLET: Connect to the supplied IEC-standard removable
AC power cord or a compatible cord.
19 SWITCHED AC OUTLET: This convenience outlet can supply switched
power to another component or accessory. It is powered ON and OFF
by the front panel POWER SWITCH or by the HTRC 1's ON and OFF keys.
The total draw of all devices connected to this outlet must not exceed
120 watts for North America version and 115W for European version.
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 power button, HTRC 1
remote control or ZR 4 cannot activate the T 785.
