Interconnection Example: Highpass-/Full Range Mode With 1 Loudspeaker System And 2 Amplifiers - Autotek A1800 Benutzerhandbuch

INTERCONNECTION EXAMPLE: Highpass/Full Range Mode with
INTERCONNECTION AMPLIFIER 1 & 2
• Connect the RCA lineouts of the headunit with the RCA jacks LINE INPUT of the amplifier with appropriate high-value RCA cables like
following:• •
RCA OUTPUT L with LINE INPUT of AMPLIFIER 1 by a Y-Connector (1F on 2M)
• •RCA OUTPUT R with LINE INPUT of AMPLIFIER 2 by a Y-Connector (1F on 2M)
• Connect the front or rear speakers with the speaker outputs by using appropriate wires like
LEFT LOUDSPEAKER with SPEAKER OUTPUT + and - of AMPLIFIER 1
• RIGHT LOUDSPEAKER with SPEAKER OUTPUT + and - of AMPLIFIER 2
• Ensure by any means, that the total impedance load per amplifier is not lower than 2 ohms.
Too low impedance cause high temperature and will shut down the amplifier operation.
• Always ensure the correct polarity of the speakers.
The interchange of plus and minus cause total loss of bass playback and could damage the speakers.
CROSSOVER SETTINGS AMPLIFIER 1 & 2
• By using bigger speakers (more than 20cm) you can set the X-OVER switch to the FULL position (Full Range Signal).
• By using smaller speakers (8.7cm - 16cm) you must 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 HIGH PASS controller and could be set between
15 Hz to 55 Hz, depending on the size of the speakers.
• The LOW PASS Controller is not in use in this interconnecting example.
LEVEL CONTROLLER AMPLIFIER 1 & 2
• Turn the LEVEL INPUT controller of the amplifier to the 5V position.
• Turn the volume controller of the headunit to 80 - 90% of its full setting.
• Turn the LEVEL INPUT controller clockwise until you hear some distortion.
• Then turn back the LEVEL INPUT controller slightly until you hear a cleaner sound.
BASS BOOST CONTROLLER AMPLIFIER 1 & 2
• The BASS BOOST controller must be turned to 0 dB position in this interconnecting example .
REFERENCE NOTE
Do not connect loudspeaker cables with the vehicle chassis. Always ensure the correct polarity
of all connections. The interchange of plus and minus cause total loss of bass playback and could
damage the speakers.
