Loudspeaker Connection: Tri-Mode (Stereo-Satellite-Subwoofer)
Germanium Two
The amplifier is likewise suitable for loudspeaker connection in tri-mode and can be used for rear deck systems
with subwoofers. (Fig. 8)
Attach the rear deck loudspeaker system at the terminals (8), as described in the section „Loudspeaker Connection:
Stereo“ above. Additionally an 8
Ω
or 4
Ω
subwoofer over a passive crossover on the L (8) and R– (8) 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 power handling 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.
