REFERENCE NOTE: Ensure always correct polarity for all connections.

Don’t connect any speaker cables to the vehicle’s ground.

Loudspeaker- and Audio-Connections

• Connect the RCA INPUTS of the amplifier to the head unit line outputs with appropriate RCA cables.

• Connect the Subwoofer with the speaker outputs (SPEAKER OUTPUT/ - +) of the amplifier by using appropriate

cables.

• Ensure that the total speaker impedance load is not lower than 1 Ohms.

• Too low speaker loads result in too high heat development and may cause the amplifier run into protection.

INPUT LEVEL - controller

• Turn the INPUT LEVEL - controller on the amplifier to 5V position.

• Turn the head unit volume controller to about 80-90% of its full setting.

• Turn the INPUT LEVEL - controller clockwise until you hear some distortion.

• Then turn back the INPUT LEVEL - controller slightly until you can hear clean sound.

REFERENCE NOTE: If this controller is cranked up too high, the amplifier produce distortions, which may cause a

“creeping death” of the amplifier (or the speakers). Usually this is called “Clipping”.

LOWPASS - controller

• The lowpass filter eliminates the higher frequencies. The recommended crossover frequency ranges between 60-100Hz,

depending on the size and response of the Subwoofer.

SUBSONIC - controller

• The SUB SONIC controller (Subsonicfilter) limits the ultralow and not hearable frequencies of the audiosignal to below,

to avoid a mechanical and electrical overloading on the subwoofer. The cut-off frequency is adjustable from 15 to 55 Hz

and depends on the size of the subwoofer.

BASS BOOST - controller

• The BASS BOOST - controller adjusts the bass boost level at 45 Hz from 0db to +12dB.

Caution! Please use the Bass Boost carefully.

Connect the RCA cable from head-unit

or a additional multichannel-amplifier

with RCA input

Connect cable from REMOTE CONTROL

with the input jack of the amplifier.

Subwoofer 1 - 8 Ohms

The optional RCA Fullrange Outputs

(OUTPUT) are forwarding the audiosignal.

A additional subwoofer can be

connected to the non-occupied

speaker outputs. In this case

ensure a impedance of 2 - 8

ohms per subwoofer.
