2 Channel Amplifier - Applications
GP1000.2 / GP1500.2
One 2 Channel Amplifier in Stereo Mode
Interconnect cable checklist:
• Connect the INPUT of the amplifier to the head unit line output with good quality RCA to
RCA cables.
• Connect the speakers with the terminal block (SPEAKER OUTPUT/ + RIGHT - and + LEFT
- and) of the amplifier.
•The minimum final speaker impedance must not be below 2 Ohm per channel. Too low
speaker loads result in too high heat dissipation and may cause the amplifier run into
protection.
• Please observe speaker channel and polarity as printed by the speaker terminal block.
Incorrect phasing of the speakers results in total loss of bass response.
Caution
Be careful not to connect speaker (-) to the ground or vehicle chassis.
X-OVER SELECT
• If larger than 20 cm speakers are used, the FULL position is recommended.
• For all smaller speakers (Ø8.7cm - Ø16cm) the Highpass-Position (HP) is recommended, which eliminates the lowest
frequencies and protects the speakers from damage. Set the crossover-frequency between 60Hz - 150Hz, depending of the
size of the installed speakers. The Highpass adjustment can be done with the FREQ - ADJUST control.
INPUT LEVEL
• Turn the INPUT LEVEL control on the amplifier to 5V position.
• Turn the head unit volume control to about 80-90% of its full setting.
• Turn the INPUT LEVEL control clockwise until you hear some distortion.
• Then turn back the INPUT LEVEL control slightly until you can hear clean sound.
BASS BOOST
• Turn the BASS BOOST control into “0dB” - position.
MODE SELECT
• The MODE SELECT - switch must be in “STEREO” - position.
