Note: When making any connections between source
components, processors or preamplifiers and the 1.3, or
when making any connections to speakers, be certain that
both the input device and the 1.3 are turned off. To ensure
that there will be no unwanted signal transients that can
damage equipment or speakers, it is always best to unplug
all equipment from AC power outlets before making any
connections. Modern electronic products often have a
“standby” mode that may be activated even though the
product may appear to be turned off.

The Signature Series 1.3 amplifier features a built-in
remote turn-on system that will automatically turn on the
amplifier when another device in the system is switched
on. To activate this system, this amplifier must be used in
conjunction with a Signature Series, other compatible
Harman Kardon products or other approved devices.

Note: Before making any connections to remote trigger
outlets, it is critical that both the 1.3 and the triggering
device be turned off. For additional safety, it is best that
these connections be made while both products are
unplugged from AC power sources.

Connect one end of the accessory cable supplied with the
2.0 or 1.0 to the 

jack ¢ on the

rear of the 1.3. Connect the other end to the jack on the
2.0 or 1.0 that carries the same identification.

If the 1.3 is not used with a compatible Harman Kardon
product, it is still possible to activate the unit for
automatic turn-on.

To control the amplifier in this manner you will need 
a small AC-to-DC power converter capable of delivering a
6- to 12-volt DC signal. The DC voltage should terminate
in a standard 3.5 mm mono miniplug, with the tip of the
plug “positive” (

). This type of converter may be

obtained as a “Power Adapter” from many electronics
retailers. Consult your dealer for further information.

Plug the AC adapter into a switched outlet that will be
activated when you wish to have the amplifier turn on.
This may be the switched outlet at the rear of an AV
receiver or other audio equipment, an AC outlet that is
part of a current sensing control unit activated by a pre-
amp or surround processor or a switched AC wall outlet.

Connect the 3.5 mm miniplug from the power converter to
the 

jack ¢ on the rear of the 1.3.

As a general rule, avoid running any input signal or
speaker wire connections next to or parallel with AC
power cords. This may cause undesired hum or other
interference that will greatly degrade signal performance.

When making connections with RCA-type plugs on
interconnect cables, make certain to gently but firmly
insert the plugs into the jacks on the rear of the 1.3. Loose
connections can cause intermittent sound and may
damage your speakers.

Connect the outputs of the 2.0 or your surround processor
to the 

™ of the 1.3. To simplify

installation, it is best to follow the markings on the rear
panel by connecting the Front Right output of the 2.0 to
the Front Right input on the 1.3, following the same
pattern for each channel.

Important Note: The 1.3 is not designed for use in
Bridged configuration. Do not connect the same input or
speaker to more than one channel.

To ensure that the high-quality signals produced by the
1.3 are carried to your speakers without loss of clarity or
resolution, we recommend that you use high-quality
speaker cable.  Many brands of cable are available, and
the choice of cable may be influenced by the distance
between your speakers and the amplifier, the type of
speakers you use, personal preferences and other factors.
Your dealer or installer is a valuable resource to consult in
selecting a proper cable for connections between your
amplifier and speakers.

Regardless of the brand or type of cable selected, we re-
commend that you use a cable constructed of high strand
count copper with a diameter of 2.5mm

or greater.
