NSTALLATION AND
SETTING THE CROSSOVER(S)
Determine your system plans and set the
crossover-mode switch accordingly. If your
system design does not include a subwoofer,
set the crossover mode to FLAT and skip to
"Setting Input Sensitivity. "

MODE SWITCH

Flat: Allows a full-range signal through to the
speakers; can be used with larger full-range
speakers such as 6" x 9"s.
HP: Allows a high-pass signal through to
the speakers; should be used with most
loudspeakers (can protect your full-range
speakers from being overdriven with low
frequencies, one cause of speaker damage).
LP: Allows bass to pass through to the speakers;
should be selected when powering subwoofers.

Initially set the crossover-frequency control
midway. While listening to music, adjust the
crossover for the least perceived distortion from
the speakers, allowing them to reproduce as
much bass as possible.
Systems using a separate subwoofer set the
crossover mode to HP (high pass) for your
full-range speakers. Adjust the crossover
frequency to limit bass, and provide increased
system volume with less distortion.
For subwoofers, choose the highest frequency
that removes vocal information from the sound
of the subwoofer.
If using the 7520a or 7540a to drive a subwoofer(s),
set the crossover mode to LP (low pass).
NOTE: The 310a, 610a, 1210a and the subwoofer
output of the 5760a are low-pass only and do not
have a crossover-mode switch.
