1 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 755 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 755’s infrared
receiver to command or control the linked unit.

IR IN and IR OUT 3 :

Connect the T 755’s IR IN to the IR OUT of ancillary

equipment. Connect also the T 755’s IR OUT 3 to another equipment
with IR IN feature. With this setup, the T 755 acts as an “IR-repeater”
allowing the equipment connected to the T 755’ s IR IN control or
command of the other equipment linked to the T 755’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 755. For non-NAD models, please check with your other product’s
service specialists as to their compatibility to the T 755’s IR features.

2 +12 V TRIGGER OUT:

There are three config12V TRIGGER

OUTPUT. Use a 3.5mm mini-jack connector to pass +12 volts at a
maximum current of 200 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 755 selects the 12V
Trigger Input to turn ON (if so assigned at the “Trigger Setup” menu) and

at the same time disables the HTR 3 and ON/OFF function of the front
panel. 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 HTR 3
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.

3 SOFT CLIPPING:

Enables NAD’s proprietary Soft Clipping circuitry on

all channels. At [ON] position, Soft Clipping gently limits the output of
the T 755 to minimize audible distortion should the A/V Receiver be
over-driven. Soft Clipping may simply be left ON at all times to reduce
the likelihood of audible distortion from excessive volume settings.
However, for critical listening and to preserve optimum dynamics, you
may wish to defeat it by setting this switch OFF.

4 FM, AM ANTENNA INPUT:

The supplied wire “dipole” FM antenna will

connect to the FM connector using the supplied “balun” adapter. It will
usually work best when mounted on a vertical surface such as a wall,
with arms fully outstretched forming a horizontal “T” perpendicular to
the origin point of the signal.

Connect the supplied AM loop antenna to these terminals. If an external
AM antenna is used, make connections to the AM and GND terminals
in accordance with the instructions supplied with the antenna. See also
section about “LISTENING TO RADIO”.

ATTENTION!

Please make sure that the T 755 is powered off or unplugged before making any connections. It is also advisable to power-down or unplug all associated
components while making or breaking any signal or AC power connections.
