Amplifier Functions
1. Speaker connection
· Never connect the speaker cables with the chassis ground. This could destroy
your amplifier.
· Check that your speakers are connected correctly which means plus to plus and minus
to minus
We recommend speaker cable from 2.5 mm² and up. Other connection variations are shown
attached.
2. BATT+
Battery + (plus) terminal. The + (plus) 12 Volt power cable must be connected with a fuse on
the battery + (plus) terminal. We recommend a 100 ampere ANL fuse and a copper cable with
a thickness of 25 mm² for cable length up to 5 metres.
3. REM
Remote terminal. The remote cable must be connected with the radio automatic antenna
terminal so that the amplifier will switch on and off automatically with the radio. If there are
2 or more amplifiers connected to this antenna terminal it might be necessary to add an
additional relay. Please consult your dealer.
4. GND
Chassis ground-terminal. The chassis ground cable must be connected very tight on a
nearby massive and electric conductive place.
5. Gain
Gain control regulates the sensitivity of the amplifier to match the signal output voltage of
your source unit.
The Gain control is not intended for volume adjustment.
Use high quality CD music and increase the volume of your source unit to 75%.
Position the Gain at the minimum and then slowly increase Gain (clockwise).
Stop at the first sign of distortion, then lower the Gain a little ( counter clockwise) to achieve
clear undistorted music at the maximum level.
6. Remote Bass Level Control ( Optional )
When using the Remote Bass Level Control you have the ability to control the level of the
subs from the driver seat.
7. RCA audio-input
These RCA inputs are to be connected with your radio preamp RCA outputs. Please use
RCA cables made for car audio, otherwise there could be disturbances. Keep these cables
as short as possible. To avoid disturbances from your car electronics, install the RCA cables
not to close from existing car cables. If your radio has only one preamp output please use
a suitable Y-RCA adaptor. If your radio has only speaker outputs you must use a
HIGH-LOW-LEVEL adaptor.
8.Fuse (P 500.1 only)
To protect the amplifier when current drawn is more than rated.
Never replace a fuse with a higher amp fuse.
Never replace a burnt fuse before checking the system for cause of malfunction.
Never bridge a fuse.

9. Bridge in
This RCA jack receives the signal sent from the master amplifier when this amplifier is bridged as
slave. DO NOT use Input Jacks when the amplifier is set as slave. All the level and functions will
be adjusted along with the master amplifier.
10. Bridge out
This RCA output signal is sent to other Pro-Series amplifiers in an bridged configuration.
11. Low Pass
To filter out the high frequency and only produce low frequency with 24 dB filter (12dB P 500.1)
to insure high quality solid bass reproduction.
12. Subsonic Switch ( not available on P 500.1)
When switched on it will filter unwanted low frequency with a 24 dB filter. This feature will
increase the power handling of your woofers.
Usually all frequencies below the enclosure tunning have increased impedance which results in
increasing the voice coil temperature.
13. Subsonic Frequency ( not available on P 500.1)
When the subsonic switch is on, it will adjust the cut off frequency filter from 20 Hz - 50 Hz
14.Bass Boost
This function will increase the bass boost level from 0 to 12 dB with center frequency at 45 Hz.
15. Power-LED
Indicates the amplifier is switched on. It will flash when there is a mal function.
16.Protection-LED
Indicated if the amplifier is in protection or other malfunction.
