3-WAY AMPLIFIER
SYSTEMS
3-way amplifier systems can be formed in different
ways, depending on how the slope selector controls
are
used.
The most
depend on the individual characteristics of the
different speakers available. Operation of these
3-way systems is the same as described under
"Operational Procedure".
NOTE:
Except where otherwise designated,
controls must NOT be set to the FLAT positions. Failure
to comply with this stipulation may result in damage to
the speakers.

Connect the stereo power amplifiers to the LOW,
MID-HIGH, and HIGH output terminals, as shown
in
Fig.
18,
and then connect the
speakers to each amplifier. After considering the
combined characteristics of each speaker combi­
nation, select suitable crossover frequencies and
slopes by means of the frequency selector and slope
selector controls (LOW LP, MID-LOW HP, MID­
HIGH LP, HIGH HP).
The MID-HIGH HP slope selector control must be
set to the FLAT position in this case.
