Channel Amplifier - Applications; One 2 Channel Amplifier In Stereo Mode With; One 2 Channel Amplifier In Mono/Subwoofer Mode - ESX SX-260 Bedienungsanleitung

One 2 Channel Amplifier in Stereo Mode (Front Amplifier) with
One 2 Channel Amplifier in Mono/Subwoofer Mode (Rear Amplifier)
Control settings of the Stereo (Front) Amplifier:
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.
Control settings of the Bass (Rear) Amplifier:
X-OVER SELECT
• In 1 Channel/Mono-Mode select the Lowpass-Position (LP), which eliminates the higher frequencies. The recommended
crossover frequency ranges between 60 - 100Hz, depending on the size and response of the Subwoofer. The Lowpass
adjustment can be done with the FREQ - ADJUST control.
INPUT LEVEL
• see descriptions for Stereo Amplifier above
BASS BOOST
• The BASS BOOST - Control increases the bass level at 45 Hz max. +12dB.
Caution! Please use the Bass-Boost carefully. The additional boost may result in clipping or overload.
MODE SELECT
• The MODE SELECT - switch must be in "MONO" - position.

Interconnect cable checklist:
•Connect the INPUT of the Stereo (Front) Amplifier to the head unit line outputs with good
quality RCA to RCA cables.
• Connect the OUTPUT of the Stereo (Front) Amplifier with the INPUT of the designated Bass
(Rear) Amplifier with a further RCA cable.
• Connect the speakers with the terminal block (SPEAKER OUTPUT/ + RIGHT - and + LEFT
-) of the Stereo (Front) Amplifier.
• Connect the Subwoofer with the terminal block (SPEAKER OUTPUT/ + BRIDGED - ) of the
designated Bass (Rear) Amplifier.
•The minimum final speaker impedance must not be below 2 Ohms for the Stereo Amplifier,
the total impedance of the Subwoofer(s) must not be below 4 Ohms. Too low speaker loads
result in too high heat dissipation and may cause the amplifier run into protection.
• If you use more than one speaker (Subwoofer), make sure that both are connected in
phase. Incorrect polarity of the speakers results in total loss of bass response.
Be careful not to connect speaker (-) to the ground or vehicle chassis.
