Signature 1.5

¡

Channel One Output:

When the amplifier is being

used in the two-channel (Stereo) mode, connect the right
channel speaker to the positive (

+

) and negative (

-

) ter-

minals. When the amplifier is being used in the Bridged
Mono mode connect the Positive (

+

) terminal ONLY to

the Negative (

-

) terminal on your speaker.

Channel One Input:

When the amplifier is being

used in the two-channel (Stereo) mode, connect the right
channel output of your preamp or processor to this input
jack. When the amplifier is being used in the Bridged
Mono mode, this jack is not used.

£

Bridge/ Normal Switch:

When the amplifier is used

for two-channel stereo operation, this switch should be
in the NORMAL position. For Bridged Mono use only,
place the switch in the BRIDGE position.

¢

Channel Two Output:

When the amplifier is being

used in the two-channel (Stereo) mode, connect the left
channel speaker to the positive (

+

) and negative (

-

) ter-

minals. When the amplifier is being used in the Bridged
Mono mode connect the Positive (

+

) terminal ONLY to

the Positive (

+

) terminal on your speaker.

Important Note:

When the 1.5 is used in the Bridged

Mono mode, do not connect a speaker with an
impedance less than 8 ohms.

Channel Two / Bridged Input:

When the amplifier is

being used in the two-channel (Stereo) mode, connect
the left channel output of your preamp or processor to
this input jack. When the amplifier is being used in the
Bridged Mono mode, connect the output of your pream-
plifier or other line-level signal source to this jack.

§

Power Amp Trigger Input:

Connect this jack to a

matching 6- to 12-VDC trigger output on a compatible
device to have the 1.5 automatically turn on from the
Standby mode when voltage is applied from the trig-
gering unit. Note that a 3.5mm mono mini-plug with a
positive tip should be used for the connection.

AC Power Cord:

Connect this plug to a non-

switched AC outlet. Due to the high-current draw of the
Signature 1.5, it is NOT recommended that the accessory
outputs on the back of audio/video components be used
to power this product.
