2.4 Bass Management
Bass management allows the user to redirect low-frequency information from any of
the five main speakers to the subwoofer; conversely, if there is no subwoofer, the
LFE information can be redirected to the left and right speakers. This is important as
the vast majority of consumer home theater speaker systems require some degree of
bass management since typically none of the five main speakers is designed to
reproduce frequencies below 80 Hz (i.e., satellite/sub speaker arrangements). The
DP562 provides the same bass management functions as a consumer Dolby Digital
decoder. Even when monitoring with full-range main speakers that require no bass
management, this function is useful for checking how redirected low frequencies
from any of the main channels may interact with the LFE-channel information.
Remember that the consumer will most likely use some form of bass management.
Accordingly, proper bass management is necessary to emulate a consumer home
theater system. See Section 3.3 for more details.
2.5 Compatibility with Existing Dolby Surround
Equipment
In the world of 5.1 digital multichannel audio such as Dolby Digital, it is important to
remember that stereo delivery in the form of broadcast, VHS, and CD will continue to
exist. However, with Dolby Surround, stereo audio formats have delivered
multichannel audio since 1982. Dolby Surround is a passive matrix four-channel (Left,
