NAD T785 Owner's Manual - page 12

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.
