The Radio Shack sound level meter, the
Paradigm "Perfect Bass Kit", and the Digital Video Essentials blu-ray disk are 3
essential tools for setting up this home theatre. The sound level meter is used
with DVE to set up the hi-def audio in the home theatre and more faithfully
reproduce the intended soundtrack. DVE is also the best calibration disk for
setting up the hi-def video, containing a great number of video test patterns
and a good tutorial as well. Even when a
subwoofer is ideally placed, the room can still have a dramatic impact on bass
performance. Room dimensions, dead spots, archways, and even furniture placement
can turn a room into an additional instrument. This state-of-the-art “bass
perfecting” system analyzes the subwoofer’s response in the room, then sets the
correct equalization parameters to attain optimal sound. The frequency response
of each PBK microphone is measured precisely and the data is used to create the
microphone’s calibration file included on the PBK software disk. Most room
equalization methods work from a single point source, taking one measurement at
the primary listening position. PBK however, provides for multiple user-selected
measurement points. Unlike many “Room EQ”
systems, PBK applies Correction to Peaks (modes) and Dips (anti-modes):
Tackling both allows the subwoofer to achieve a far more accurate and natural
room response.
