signals to be amplified by amplifiers A and B.
• A B position:
Amplifies both of the signals input to amplifiers
A and B.
• A position:
Amplifies only signal input amplifier A with
both amplifiers A and B.
8 INPUT SENSITIVITY control (A.ch/B.ch)
Set this control according to the pre-output level
of the center unit connected with this unit.
NOTE
For the pre-output level, refer to the
<Specifications> in the instruction manual of the
center unit.
9 FILTER FREQUENCY control (A.ch/B.ch)
This control adjusts the frequency band output
from this unit.
The frequency range is set with the "FREQ.
RANGE" switch.
0 FILTER switch (A.ch/B.ch)
This switch allows to apply high-pass or low-pass
filtering to the speaker outputs.
• HPF (High-Pass Filter) position:
The filter outputs the band of higher
frequencies than the frequency set with the
"FILTER FREQUENCY" control.
• OFF position:
The entire bandwidth is output without
filtering.
• LPF (Low-Pass Filter) position:
The filter outputs the band of lower frequencies
than the frequency set with the "FILTER
FREQUENCY" control.
- FREQ. RANGE swtich (A.ch/B.ch)
This switch selects the range of filter frequency.
