Loudspeaker Connection Tri-Mode - Rainbow Germanium Four Einbauanleitung

Loudspeaker Connection: Tri-Mode Germanium Four
(Stereo-Satellite + Subwoofer)
The amplifier is likewise suitable for loudspeaker connection in tri-mode at the "FRONT" and "REAR" outputs
and can be used for rear deck systems with subwoofers. With the application of this wiring suggestion the
connection of the loudspeaker system and the subwoofer should occur on the rear deck at the outputs "REAR" and
connection of a front loudspeaker system at the outputs "FRONT" (Fig. 10).
Attach the rear deck loudspeaker system at the terminals (8), as described in the section „Loudspeaker Connection:
Stereo" above. Additionally an 8Ω or 4Ω subwoofer over a passive crossover on the clamps +RL and RR– will be
attached.
The mechanical load of the woofer of the rear deck loudspeaker system will fall at low frequencies because of the
limits on electrical load set by the cone excursion when no security measures for the lower frequency range have
been made. If the loudspeaker system is operated without additional high pass, the total power handling of
the system will be determined by the maximum power handling of the loudspeaker system.
Disadvantages of this circuitry are the decreased channel separation as well as the inability to regulate the
subwoofer level. The advantage is, however, in the compactness of the system, which is ideal for elevated
placement.
