FUNCTIONS (PB618)
9.PROTECTION LED
The protection circuitry will disable the amplifier if it senses an input overload,
speaker short circuit of extreme high temperature conditions. When the protec
tion circuit is in operation the LED indicator on the unit will light indicating that
the
amplifier has gone into a self preservation mode. At this time please check
your system to see what is causing the protection circuit to fire. The amplifier
can
be reset by turning the remote power o and then on again. If the system
shuts down because of a thermal overload condition, allow the amplifier to cool
down
before restarting If the amplifier shutdown because of an input overload
or speaker short circuit please be sure to correct these conditions before
restarting the amplifier.
10.POWER SUPPLY
A. +12V
To connect +12V DC power supply wire from the terminal of battery.
B. GROUND
To connect the ground wire from the chassis of the automobile.
C. REMOTE
To connect the control wire which provides remote turn on and o of the ampli
fier by the radio/cassette player. (Usually The Auto Antenna Lead)
11.POWER FUSE
The
power fuse protects both this amplifier and the automobile electrical
system from short circuit conditions.
12.SPEAKER TERMINALS.
The speaker terminals are for high conductivity and minimum impedance loss.
The terminals are facing upwards for easy wiring in tight situations. Be sure
to strip just enough insulation o your speaker wires that will fit under the
screw plate to help ensure against speaker wire sho circuits.
13.TRI-MODE BRIDGING CAPABILTY.
The Amplifier can be bridged into the following systems.
A three channel Mode. Bridge Channels 3 & 4 into one high power channel for
subwoofer application while leaving channels 1 & 2 in the stereo mode for satel
lite components.
B. Two Channel Mode. Bridge channels 1 & 2 into one high powered channel.
Bridge channels 3 & 4 into a second high powered channel. Be sure to utilize
speaker which can handle at rated power on the bridged channels.
14.MUTE TURN ON CIRCUIT
4
The Amplifier features an anti-thump delay circuit. This circuit eliminates irritat
ing thump noise some times experienced with cheaper amplifiers when they are
turned on.
