2-Way Amplifier Systems - Pioneer D-23 Operating Instructions Manual

SELECTION OF CROSSOVER FREQUENCIES
BETWEEN LOW MID-RANGE AND HIGH MID­
RANGE FREQUENCIES (320Hz-3.2kHz) AND
BETWEEN HIGH MID-RANGE AND HIGH FRE­
QUENCIES (1.6kHz-16kHz)
(Connections to MID-LOW, MID-HIGH, and HIGH
Output Terminals)
Connect stereo power amplifiers to the MID-LOW,
MID-HIGH, and HIGH output terminals, as shown
in Fig. 22, and then connect appropriate speakers
to each of the amplifiers. After considering the
characteristics of each speaker combination, select
suitable crossover frequencies and slopes by means
of the frequency selector
controls (MID-LOW LP,
HIGH LP, and HIGH HP).
The MID-LOW HP slope selector control must be
set to the FLAT position in this case.

NOTE:
Except where otherwise
controls must NOT be set to the FLAT positions. Failure
to comply with this stipulation may result in damage to
