Boston Acoustics LCAi220 - Manual (Page 14)

Set Up Instructions
Central Music System
Configuration
Adjust the levels for the central music
system. If an in-wall volume control is
used, follow its instructions for
configuration before continuing.
If a volume control is not used, start with
the volume on the central music system
low, and turn it up until a comfortable
volume level is achieved.
Adjusting the Highpass (HP)
Filter on the LCAi220
The LCAi220 features a selectable
highpass filter to remove low frequency
information from the local speakers
when amplified by the LCAi220. This is
especially useful when using smaller
speakers or when use in conjunction
with a powered subwoofer.
Flat: No filter engaged, larger
speakers
30Hz: Larger speakers with a
powered subwoofer or
smaller speakers without
a powered subwoofer
100Hz: Smaller speakers with or
without a powered
subwoofer
Note: If at higher volumes the sound
becomes distorted, especially during
heavier bass passages, it may be
necessary to increase the highpass
setting to a higher value.
