Input Level control

Inputs may be low level from the RCA output of the car stereo or high level from the car stereo speaker output.Low level = RCA is to prefer for the best sound quality.

Important

Use either the low level or the high level input, do not use both at same time.

Low level input

Use a pair of shielded stereo audio cables with RCA type jack. Most trunk-mount amplifiers need a 20 feet RCA cable ( appr 5 – 6 meters). Most under the seat installations require 12

feet ( 2 – 3 meters) RCA cables. Avoid placing the RCA cable close to speaker cables, power cables and remote control cable. Connect to in- put socket A & B.

The input level control, 5V – 0,25 V, matches the output of your ra- dio to the input of the amplifier. After installation is complete, make sure the input of the amplifier is turned down all the way ( counter- clockwise at 5V ). Play a tape or CD, make sure all bass or treble settings or equalizer are flat, and turn the volume of the radio up until you just start to hear distortion. Turn the volume control down just a bit. On the amplifier increase the input level control ( clockwise or to the right ) until you just start to hear distortion, then back the level control just a bit. Now your radio and amplifier levels are matched.

The Subsonic filter blocks the very deepest frequencies from reaching the subwoofers. It has a variable frequency from 15 to 50 Hz. A typical set- ting is 25-30 Hz when used with subwoofers.The filter can be switched IN-OUT.

Low Pass Filter

Automatic turn on when using high level input. With the Hi/Low input swich set to Hi, the amplifier turns on automatically on high input.You dont need to connect a separate remote wire from your head unit.

When using High Level input:

Set the switch to position ”Hi / Level”

When using Low level input:

Set the switch to position ”Low / Level” If the switch is set to wrong position, the amplifier still works, but the risk for disturbances or distortion increases.

The LPF ( low pass filter ) mostly used for subwoofers. It will allow low frequencies only and blocks higher frequencies. A typical setting is 50 – 80 Hz. The filter can be switched in and out and you can select between two different slopes, 12 dB/ octave or 24 dB/ octave. Choose the slope and the set- ting that sounds best in your car.
