INTERCONNECTION EXAMPLE
5-channel-mode: 2 x Stereo-System (Front & Rear) + 1 x Subwoofer
FUNCTIONAL INSTRUCTIONS
INTERCONNECTION
• Connect the RCA lineouts of the head unit with the RCA jacks LINE IN of the amplifier with appropriate high-value RCA cables.
If your head unit is equipped with a separate SUB OUT use this for the CH5 inputs.
• Connect the front speakers with SPEAKER CH 1 - / + CH 2 -, rear speakers with SPEAKER 3CH - / + 4CH -
Ensure that the total impedance load of each speaker is not lower than 2 ohms.
• Connect the subwoofer with + SUB OUTPUT -. Ensure that the total impedance load of the subwoofer is not lower than 1 ohm.
Too low impedance cause high temperature and will shut down the amplifier operation.
INPUT MODE SWITCH
• Select the 5CH position on the INPUT MODE switch. If there are only two RCA stereo audio cables from the head unit available,
connect the CH1/2 and CH3/4 RCA line inputs and select the 4CH position. If you have only one RCA stereo cable, connect the
CH1/2 line inputs an select the 2CH position.
CROSSOVER SETTINGS CH1/2 & CH3/4
• When using bigger speakers (more than 20cm) set the X-OVER switch to the FULL position (Full Range Signal).
• When using smaller speakers (8.7cm - 16cm) set the X-OVER switch to the HP position (Highpass Mode) to avoid any
damage by lower frequencies on the speakers. The cut-off frequency is adjustable with the HP controller and should be set
between 60Hz to 150Hz, depending on the size of the speakers.
• The LP controller from CH3/4 is not in use in this interconnecting example.
LEVEL CONTROLLER CH1/2 & CH3/4 & CH5
• Turn the LEVEL controller of the amplifier to the MIN position.
• Turn the volume controller of the head unit to 80 - 90% of its full setting.
• Turn the LEVEL controller clockwise until you hear some distortion.
• Then turn back the LEVEL controller slightly until you hear a cleaner sound.
BASS BOOST CONTROLLER CH5
• The BASS BOOST controller is continuously adjustable from 0dB bis +18dB.
Use this controller carefully.
LP CONTROLLER CH5
• The LP (low pass) controller is for the adjustment of the Cut-Off-Frequency, which should be between 60Hz and 100Hz,
depending on the size of the subwoofer.
SUB SONIC CONTROLLER CH5
• 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. If this controller is set higher than the LP controller no audio is hearable.
BASS REMOTE CH5
• The enclosed BASS REMOTE CONTROLLER adjusts the bass-level on the subwoofer channel CH5 e.g. from the driver’s seat.
Please use only the enclosed bass remote controller and cable.
Connect the stereo RCA output (FL/FR, RL/RR and SUB OUT)
of the head unit with LINE IN CH1/2, CH3/4 and CH5 SUB IN
of the amplifier.
