Before making connections, be sure to turn the power off to all audio
components. Insulation tubes for the speaker leads and the power supply
leads are supplied with the 3547, route the speaker leads and the power
supply leads separately through these tubes.
CAUTION:
Always keep the RCA inputs of the 3547 connected to a signal source
while the amplifier is in operation.
@ Speaker Output Terminals
The 3547 has a set of speaker outputs. Be sure to observe correct
speaker output polarity and phasing. In the stereo mode, connect the
right speaker output to the right speaker and the left to left. Connect the
positive output to the positive speaker terminal and the negative to
negative. In the bridged mode, connect the left positive to the positive
terminal on the speaker and the right negative to the negative terminal of
the speaker. Do not use the negative (—) speaker terminal commonly for
the right and left speakers or connect them to the vehicle's chassis
ground.
NOTE:
Do not connect speaker leads together or to chassis ground.
@ RCA Input Connectors
Connect these connectors to the line out leads on your head unit using
RCA extension cables (solid separately). Be sure to observe correct
channel connections; Left to Left, Right to Right, Front to Front, and Rear
to Rear.
