with a maximum output of 580 watts.
* Direct connection can be made with the speaker
output of your car audio if it is not equipped
with the line output (High level input
connection).

power.
* Pulse power supply
This unit has a built-in power regulator which converts
the power supplied by the DC 12 V car battery inte high
speed pulses using a semiconductor switch. These pulses
are stepped up by the built-in pulse transformer and
separated into both positive and negative power supplies
before being converted into direct current again. This is to
regulate fluctuating voltage from the car battery. This
light weight power supply system provides a highly
efficient power supply with a low impedance output.
Location and Function of Controls
1} MODE indicator
Indicates HI-CURRENT mode or HI-VOLTAGE mode.
2] POWER/PROTECTOR indicator
¢ OVER CURRENT lights up in green during normal operation. The color will
change from green to amber when receiving a powerful signal.
¢ OFF SET lights up green during normal operation. The color will change
from green to amber when the voltage going out to the Speaker terminal or
the Pin Jack is too high .
¢ THERMAL lights up in green during normal operation. The color will
change from green to amber when the temperature rises to an unsafe level.
The color will return to green when the temperature returns to normal.

FILTER
.{6] FILTER-selector switch
:
When the switch is in the LPF position, the filter is set to low-pass. When in
the HPF position, the filter is set to high-pass.
HI-CURRENT/HI-VOLTAGE mode switch (located on the bottom of the unit)
Remove the bottom cover to access the switch.
eIn HI-CURRENT mode the speaker impedance is 1 to 2 Q. This
mode sends a signal via parallel circuits for a powerful sound
¢ In HI-VOLTAGE mode the speaker impedance is 2 to 4 Q. In this mode
you can enjoy clear sound with the dynamic range.
