4.GND
Connect this cable directly to the frame of the vehicle. Make sure the metal frame has been
stripped of all paint down to the bare metal. Use the shortest distance possible. It is always a good
idea to replace the factory ground at this time with a larger cable equal to the new amplifier power
cable or larger.
CAUTION:
Do not connect this terminal directly to the vehicle battery ground terminal or any other
factory ground points.
5.GIAN
The level control will match the amplifiers sensitivity to the source units signal voltage. The
Operating range is 200mV minimum to 5V maximum. This is NOT a volume control!
6.LPF
This control is used to select the desired low pass x-over frequency. The frequency can be
adjusted from 40Hz to 220Hz for all bass mono models.
7. Subsonic Filter Control
This control can filter out unwanted low frequency from 10Hz (OFF) to 50Hz. This function will
increase the power handling of your woofers.
8. Bass Boost Frequency
By adjusting these two knobs, you can boost a wanted frequency to a wanted level. The center
boost frequency is adjustable from 30Hz to 90Hz,
9. BASSBOOST
This knob adjust the boost level of the bassboost center frequency.It can be adjus-ted from 0 to
12dB, Combining with bassboost frequency, you can accurately match the amplifier performance to
woofer response.
10. Q-Control
This knob adjust the curve shape of bassboost. Turn it to narrow side will make the boosted
frequency narrow and sharp,turn it to wide will extend the boosted frequency range. Combining with
bassboost frequency and bassboost level adjusting,you can
a perfect bass response matching
get
your system.

12. X-over mode and frequency Control
(Only PK1400.4M )
These controls allow control over the frequencies played for PK1400.4M. There is an option
for Low Pass, Full Range or High Pass. In LP mode the frequency range is from 50Hz to
200Hz(PK1400.4M is from 50Hz to 750Hz) , In HP mode the frequency range is from 15Hz to 200Hz.
13. Bass Boost Frequency and Level Control
By adjusting these two knobs, you can boost a wanted frequency to a wanted level. The center
boost frequency is adjustable from 30Hz to 90Hz, the boost level is adjustable from 0dB to 12dB.
14. HPF
This control is used to set the HPF crossover frequency for the front amplifier er channel. The
frequency is adjustable between OFF and 200Hz.

15. LPF/FULL/HPF selector & frequency adjustive knob
This switch and knob control Low Pass Filter, High Pass and Full pass function. When set to
LPF, the amplifier will cut off high frequencies and should be used driving subwoofers. When set to
HPF, the amplifier will cut off low frequencies and should be used driving full range speakers or
tweeter. When set to Full, Full range of frequencies are reproduced and output to the speakers. In
another words the filters are “OFF”.
16. 4CH/2CH Switch(PK700.4M/PK1400.4M)
This knob switch 2ch/4ch input mode. When press in, Amplifier works at 2CH input mode, CH-B
input will be paralleled to CH-A, CH-B input jack will be dummy. When pressed knob out, Amplifier
will work at 4CH mode.
