will be filtered.
About the protector
indicator
The amplifier has a built-in protection circuit to
protect the transistors and speakers in following
conditions:
The amplifier is overheated.•
A DC current is generated in•
speakers.
The battery voltage is too low or too•
high. Or
The speaker terminals are short•
circuited.
When the PROTECTED indicator
lights up in red, the amplifier shuts
down automatically. In this case
please:
1Take out the disc or tape and turn off the
car audio.
2Check the cause of the malfunction.
3If the amplifier is overheated, let it cool
down.
4 Use your power
amplifier
Select HPF/LPF mode
1Slide LPF or HPF to the selected mode.
HPF (high-
pass-filter)
180Hz More low frequency
signal is filtered. Select
this if you prefer less
bass effect.
OFF
LPF (low-
pass-filter)
80Hz More high frequency
signal is filtered. Select
this if you prefer
stronger bass effect.
OFF
Adjust input level
To ensure sound quality, adjust input level to
match it with the car audio’s output voltage.
1Check the line output voltage of the
connected car audio.
2Rotate INPUT LEVEL to select a
matched voltage: 0.3V to 6V.
