OWNER'S MANUAL AND
INSTALLATION GUIDE
INTRODUCTION
Latest technology, high sound quality, powerful delivery and LINEAR POWER™
reliability all describe LINEAR POWER™ amplifiers. With new "HV" circuitry,
their value increases. Versatile capabilities such as stereo, mono or mixed
stereo/mono operation and 2 ohm capability make these amplifiers extremely
desirable to build an entire system around or begin a system.
TECHNICAL DESCRIPTION
The "HV" series amplifiers are a series of amplifiers based around our dedication
to high voltage designed products. These amplifiers have an inverted channel,
and quiet turn on circuit has been added for improved sound performance. The
amplifier design incorporates a new proprietary hybrid mosfet driven bipolar
power supply for increased dynamic headroom and efficiency. The TO-3 output
stages of these amplifiers will deliver a significant increase in power into 2-ohm
stereo loads. Amplifier reliability is accomplished by operating the output
transistors at 50% of their maximum rating.
WIRING
Disconnect battery ground cable before making any power connections.
RED WIRE: +12 volts. Connect directly to battery positive terminal and should be
fused within 18 inches from the battery and another fuse where the connection to
the amplifier is made. Remember to use the proper size fuses. WARNING:
USING OVERSIZED FUSES IS DANGEROUS AND WILL DAMAGE YOUR
AMPLIFIER! See specifications for proper fuse size.

BLACK WIRE: Negative Ground. Connect to clean unpainted metal surface on
char chassis.
RED/WHITE WIRE: Remote turn on lead requires 12 volts; connect to power
antenna lead from radio. When this is not available, you may connect to a +12
volts wire that is on with the ignition on or in the accessory position.
RCA CONNECTIONS: Connect with quality-shielded patch cords from source,
crossover, or any other sound processor.
SPEAKER CONNECTIONS: Connect speaker terminals to amplifier, facing the
terminal, left to right, Left (-), Left (+), Right (-), and Right (+). For mono
operation use left positive (+) and right negative (-). These amplifiers are capable
of 2-ohm operation in stereo or 4 ohm in mono.
OPERATING THE AMPLIFIER AT LESS THAN THESE RATINGS WILL
CAUSE AMPLIFIER FAILURE AND VOID YOUR WARRANTY.
NOTE: The 2.2HV has internal taps for 2-ohm operation. To access, remove
bottom cover. They are located near the middle of the amplifier and are set to 4
ohms at the factory. To change to 2-ohm operation, pull the quick disconnects off
the taps marked “4” and place them on the taps marked “2”. This will ensure
safe operation into 2-ohm stereo loads, as well as, 4 ohm bridged loads.
GAIN ADJUSTMENT
Set the amp gain to minimum, turn the source up until it just starts to distort, then
back down slightly. This is the point where the output of the source is cleanest.
Now adjust the amplifier gain up until it just starts to distort and back down
slightly. This will allow the source and amp to reach maximum usable output at
the same time.
MOUNTING
1.The amplifier works best if it is kept as cool as possible. Mount in a position
that allows air to flow freely through the fins. Be sure there is ample space above
the amplifier to avoid trapping heated air rising from the amplifier. The amplifier
should not be mounted upside down. Avoid mounting any amplifier in the dash or
on the firewall to avoid noises being radiated directly onto the case.
2.The case of your amplifier is designed to act as a noise shield. To maintain this
protection, be sure the metal case of the amp does not touch the metal of the
car. Do not remove or damage the rubber grommets, which provide electrical
insulation and vibration isolation.

GENERAL TROUBLESHOOTING
NO SOUND: Check all connections. Check fuses. With a meter be sure there is
+12 Volts on the main power wire and the turn on wire, but not on the ground
wire. Check by substitution or other method for proper operation of music source.
BLOWS FUSE: Check all connections to be sure all power wires and speaker
wires do not touch ground or each other. Re-check polarity of main power wires.
SHUTS OFF: This amplifier is equipped with a thermal and short circuit
protection. In the unlikely event of excessive temperature or improper speaker
impedances, the amp will turn itself off. When the condition is corrected
(temperature decreases or speaker short is fixed), the amp will turn itself back
on. To avoid damage to the speakers, turn volume to a minimum while waiting for
the amp to turn itself back on.
