• REM: The unit is turned on by applying + 12 Volts to this terminal. This terminal does not draw heavy current like the tow Power Terminals so a thinner connecting wire is acceptable. Standard 20 GAUGE is ne and the standard color blue. 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 larger than 10 - Gauge (AWG. 10). OPERATION After the ampli er has been installed and all connections have been made carefully and securely, turn the radio ON so that the ampli er is switched on automatically. After a short power-on period, the ampli er 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 o the radio immediately - the ampli er will also switch o automatically - and check if all connections have been made correctly. GAIN = INPUT LEVEL CONTROL The input level control allows the system to work well within a wide range of output level. Choose the adjustment in the way that you achieve a sound most possibly without any distortion. As a guideline the following procedure is recommended: • If you use several ampli ers, the adjustment has to be made for each set separately. Tune in the volume of your car radio to2/3 of the maximum volume. Now turn the gain control of the ampli er 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 nished now. • Attention! If you use 2 Ohm speakers in stereo mode. Tri-mode or 4 Ohm speakers in bridge mode and the overload protection is triggered out, turn the gain control to "Min" direction, until the operation is free of trouble. www.PyleUSA.com 7

REM:
The unit is turned on by applying + 12 Volts to this terminal. This terminal
does not draw heavy current like the tow Power Terminals so a thinner
connecting wire is acceptable. Standard 20 GAUGE is fine and the standard
color blue. 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 larger than 10 - Gauge (AWG. 10).
OPERATION
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.
GAIN = INPUT LEVEL CONTROL
The input level control allows the system to work well within a wide range of
output level. Choose the adjustment in the way that you achieve a sound
most possibly without any distortion.
As a guideline the following procedure is recommended:
•
If you use several amplifiers, the adjustment has to be made for each set
separately. Tune in the volume of your car radio to2/3 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 2 Ohm speakers in stereo mode. Tri-mode or 4 Ohm
speakers in bridge mode and the overload protection is triggered out, turn the
gain control to "Min" direction, until the operation is free of trouble.
