When the word 

IGNATURE

is

illuminated in blue, the 1.3 is in a normal operating
condition.

The color of this indicator varies with

the status of the 1.3. It is red when the unit is off, amber
in the standby mode, and flashing green during warm-up.
If the indicator flashes and alternates between red and
amber, the 1.3 is in the protect mode, indicating a
problem in the unit or connections to the speakers.

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

2

or greater.

6

Cable with a diameter of 1.0mm

2

may be used for short

runs of less than 4 meters. We do not recommend the use
of cables with a smaller diameter due to the power loss
and degradation in performance that will occur.

Cables run inside walls should have the appropriate
markings to indicate listing with the appropriate safety
agency standards that may be required in your area.
Questions about running cables inside walls should be
referred to your installer or a licensed electrical contractor
who is familiar with the applicable building or electrical
codes in your area.

The final step of the installation process is to connect the
amplifier to your speakers using high-quality cable. A pair
of binding posts is provided for each channel output. 

Note that one conductor of the speaker cable will have no
markings or an indication of “

” for negative polarity, and

the other will have a red line, brand-name markings, a
colored thread or some other positive-polarity indication. 

The wire with the positive indication should be connected
to the red terminals on both the 1.3 and your speakers.
The negative wire should be connected to the black
terminal on the 1.3 and the speakers.

If bare wire is used for connections, strip approximately

3

⁄

4

˝

(20 mm) of insulation from the end of each wire and

carefully twist the strands of each conductor together. Be
careful not to cut the individual strands or twist them off;
for optimal performance, all strands must be used.

Next, loosen the knobs of the speaker output terminals far
enough so that the cap moves back on its threads past the
holes at the rear of the terminal. Making certain that you
observe polarity by connecting the negative (

) wire to

the black terminal and the positive (

) wire to the red

terminal, pass the exposed wire through the hole until the
wire is visible from the bottom end. Holding the wire in
place, twist the cap back so that the connection is secured.
Do not overtighten or use tools, as this may damage the
plastic terminal cap or break the delicate wire strands and
decrease system performance.

Important Note: When making speaker wire connec-
tions, be certain that none of the strands from one lead
touch any other lead. This will cause a short circuit and
may damage your amplifier or speakers. Damage from
short circuits caused in this manner is not covered by the
product warranty.

Finally, run the cables to the speaker locations. It is highly
recommended that the length of cable connecting any pair
of speakers be identical. For example, make certain that the
cable length connecting left and right front or left and right
rear (surround) speakers is identical, even though one
speaker may be physically closer to the amplifier than the
other. Do not coil any excess cable, as this may become an
inductor that creates frequency response variations in your
system.

Connect the wires to the speakers, again being certain to
observe proper polarity. Remember to connect the
negative or black wire to the matching terminal on the
speaker. Similarly, the positive or red wire should be
connected to the like terminal on the speaker.

Note: While most speaker manufacturers adhere to an
industry standard of using black terminals for negative and
red ones for positive, some manufacturers may not adhere
to this configuration. To ensure properly phased
connections and optimal performance, consult the
identification plate on your speaker terminals, or the
speaker’s manual to verify polarity. If you do not know the
polarity of your speaker, ask your dealer or installer for
advice before proceeding, or consult the speaker’s
manufacturer.

The Signature 1.3 may be operated in either a manual or
automatic mode. If the unit is being used in standalone
operation you should follow the instructions below for
Manual Operation. When the 1.3 is connected to another
Signature Series product or to another compatible device,
follow the instructions for Automatic Operation.

Operation of the Signature Series 1.3 is simple. There are
no controls to adjust once the installation is complete.

For conventional, standalone operation, first make all
connections to speakers and input sources as outlined on
the previous pages. Make certain that the front panel

1 is in the fully extended “off” position

and then connect the 

£ to a wall-

mounted AC outlet with sufficient current capacity. Note
that the 

3 will glow red.

Turn the unit on, press the front panel 

1

until it is flush with the front panel. Once the switch is
turned on, the 1.3 will go into a brief warm-up mode, as
indicated by the 

3 flashing green. This is

normal, and it protects your speakers from damage as the
amplifier stabilizes.

When the 1.3 is fully ready for operation the LED
Indicator will go out and the 

2 will

glow blue behind the word 

IGNATURE

. At this point you

will begin to hear audio from the speakers connected to
the 1.3.

You are now ready to enjoy the finest sonic performance
available. No further adjustments are needed, as all
volume controls and/or level adjustments are made at
your preamp controller or surround processor.

To turn the 1.3 off, press the 

1 until it

protrudes from the front panel. The unit is in the “off”
position when the LED Indicator returns to a red color.

Note: Always turn on the source components and
processor in your system first, and turn on your amplifier
last. This avoids the possibility of any turn-on pops or
transients from other equipment being amplified and sent
to your speakers, where they may cause damage. Always
start with a low volume level on your controller or
preamp to avoid damage to your speakers.

Before proceeding, make certain that the connection
between the 1.3 and 2.0 or 1.0 processor/tuner or other
trigger source has been properly made as outlined
previously. At this point the triggering unit should be
turned off.

With the 

1 in the fully extended “off”

position, plug the 

£ into a wall-

mounted AC outlet with sufficient current capacity. The

3 will light up in a red color.

Press the 

1 so that it is in the “on”

position and flush with the front panel. At this point the

3 will turn amber, indicating that the 1.3

is in a Standby mode and ready to turn on when it
receives a signal from the Signature 2.0 or other device.

To activate the 1.3, turn on the Signature 2.0 or the other
device that is connected to the 

¢.

Once the trigger signal is received the 1.3 will go into a
brief warm-up mode, as indicated by the 

3 flashing green. This is normal, and it protects your
speakers from damage as the amplifier stabilizes.

When the 1.3 is fully ready for operation the LED
Indicator will go out and the 

2 will

glow blue behind the word 

IGNATURE

. At this point you

will begin to hear audio from the speakers connected to
the 1.3.

Once your system is turned on, you are ready to enjoy the
finest sonic performance available. There are no controls to
adjust. All volume and level adjustments are made by your
preamp, controller or surround processor.

At the conclusion of your listening session, there is no need
to manually turn off the 1.3. When the 2.0 or other
triggering device is turned off, the 1.3 will return to the
Standby mode and the 

3 will turn amber.

Important Note: If you will not be using your audio
system for an extended period of time, such as during 
a vacation, it is always a good idea to turn the unit off
using the power switch. This will prevent the automatic
turn-on circuits from accidentally turning the system on
during your absence.
