NOTES ON THE POWER SUPPLY:
Connect the +12V power input lead only after all other leads have been connected.
Be sure to connect the ground wire of the unit securely to a metal part of the car.
A lose connection may cause a malfunction of the amplifier.
REM: The unit is turned on by ap12 Volts to this terminal. This terminal does
not draw heavy current like the tow Power Terminals so a thinner connecting wire is
acceptable. Standard 18 GAUGE is fine and the standard color is yellow. If the radio is
equipped with a Power Antenna control wire, it can drive this terminal. If the Power
Antenna wire is already in use, you can still splice into it. With this method, the unit will
turn on automatically with the radio.
Use the power supply lead with a fuse attached whose value is the same as original
fuse.
Place the fuse in the power supply lead as close as possible to the car battery.
During a full power operation, Maximum current will run through the system.
Therefore, make sure that the leads to be connected to the +12V and GND terminals
of the unit respectively must be at least 10-Gauge (AWG.10).
POWER CONNECTION LEADS
After the amplifier has been installed and all connections have been made carefully and
securely, turn the radio on so that the amplifier is switched on automatically. After a short
power-on period, the amplifier reaches its full performance.
Now turn up the volume slowly using the volume control of the radio. If there is no sound
or only a distorted replay, switch off the radio immediately - the amplifier will also switch
off automatically - and check if all connections have been made correctly.
POWER LED INDICATOR
After the orderly connection of the three power terminals, the LED indicator shines green
and goes out with off.
PROTECT = LED PROTECTION INDICATOR
This set is equipped with an overload protection. immediately upon overloading (due to
much increased temperature) the overload protection is activated , and the red LED
indicator is shining. Through this the amplifier is protected against damage. In case of
thermal protection a cartain short cooling time must be allowed after which the amplifier
automatically resumes operation.
LEVEL CONTROL
The input level control allows the system to work well within a wide range of output level.
Choose the adjustment in te way that you achieve a sound most possibly without any
distortion. As a guideline the following procedure is recommended:
If you use several amplifier, the adjustment has to be made for each set separately tune in
the volume of your car radio to 2/3 of the maximum volume. Now turn the gain control of
the amplifier from "Min" to "Max" direction until you can hear distortions. Then turn the
level control a little back to "Min". The gain control adjustment is finished now.
Attention! If you use 1 Ohm speakers the overload protection is triggered out, turn
the gain control to "Min" direction, until the operation is free of trouble.
LPF CONTROL
