Boston Acoustics VS 344 - Manual (Page 6)

Bi-amplifying
The dual input terminals of the VS 325C, VS 344, and VS 336 also allow for
bi-amplifying. Two separate amplifier channels are used to drive the speaker.
One channel drives the bass speakers while the other drives the midrange/tweeter.
This can provide significant improvements in audio quality and dynamic range.
In this configuration the metal straps that connect the two set of terminals are
removed. The amplifier channel driving the midrange/tweeter is connected to
the top terminals; the amplifier channel for the bass speakers is connected to the
bottom terminals.
Operation
When using the VS 240, VS 260, or VS 224 speakers in a Dolby® Digital or DTS™ home theater system, set the speaker type to “Small”
in the system set up procedure. When using the VS 336, VS 344, or VS 325C in a Dolby® Digital or DTS™ home theater system, the
speaker type setting can be set to either “Large” or “Small”. In the “Large” setting they may produce a more full sound. Try both settings
and use the one that sounds best with the broadest range of source material. When using the speakers in a Dolby Pro Logic® home
theater system, make sure the receiver’s center channel mode is set to “Normal.”
Some Dolby Digital receivers/processors offer different setup options for each source or surround mode (e.g., CD-stereo, videotape,
Dolby Digital, Pro Logic). If you are using a subwoofer in your system follow your equipment’s instructions to ensure that the
subwoofer output is turned on and that the speakers are set to “Small” in each mode.
If your receiver has an adjustable subwoofer crossover, we recommend setting it between 80Hz and 120Hz. Refer to the owner’s
manual for your A/V receiver for any additional recommendations on system operation.
NOTE: A Boston Acoustics powered subwoofer will add impact and realism to both music and film sound tracks. Contact your
Boston Acoustics dealer for recommendations on subwoofer models for your application.
Maintenance and Service
The high gloss finish of the VS Series cabinets is made to the standard of high quality furniture. It should be cared for in the same
way. Before you use any cleaning or care products, test a small, inconspicuous part of the cabinet. Be sure the results are what you
want before doing a final application.
For day-to-day care the speaker enclosures may be cleaned using a soft cloth to remove fingerprints or to wipe off dust. All wiring
connections should be inspected and cleaned or remade at least once a year.
If a problem does occur, make sure that all connections are properly made, secure and clean. If a problem occurs in one loudspeaker,
rewire that speaker in a different location within the system. Should the problem persist then the problem is within the speaker. If
the speaker sounds fine in the new position it is a strong indication of a more in-depth issue with the electronics in the system. In the
event that your speaker ever needs service, contact your local Boston Acoustics dealer or visit bostonacoustics.com/dealers for a list
of dealers in your area.
