Calibration
Proceed to your AV receiver/processor's
guided setup procedure. During this process
you may be required to turn the volume of
each channel up from -10dB (default) to
obtain sufficient level from your subwoofers.
TIP To confirm two connected subwoofers
are outputting audio correctly, you may
wish to do some testing while playing pink
noise or music. Turn the volume of channel
1 to mute (min) and back again, followed by
channel 2 to mute (min) and back again.
This will help ascertain both channels are
connected and delivering sound correctly.
After running the AV receiver/processor's
guided setup procedure, adjusting subwoofer
level manually is often required to suit the
listener preferences. It is recommended
to adjust the subwoofer levels within the
receiver/processor menus rather than using
the KA-1100 amplifier front controls. Boosting
or cutting the subwoofer level by up to 9dB
is not uncommon to achieve the desired
result. Adjusting lowpass settings in your AV
receiver/processor may also be beneficial to
control the bass frequency range sent to your
KA-1100 amplifier and connected subwoofers.
When setup is complete, fit the magnetic
front panel facia to the KA-1100 (page 2, figure 1).
