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.

Under some conditions, such as a shorted speaker wire,
DC voltage on an input connection or thermal overload,
the amplifier will place itself in a “protect” mode to
prevent damage to the amplifier. When this happens, the
LED Power Indicator will flash and alternate between red
and amber.

When this occurs, IMMEDIATELY turn off the unit using
the power switch and correct the problem. Then turn the
unit back on. If the unit continues to go into a protect
mode, contact your dealer or installer for assistance.
