Special Features of the Emotiva DMC-1
Bass Management
Unlike higher frequencies, it is difficult to discern exactly from which direction lower bass is
coming. The DMC-1 has a bass management system which takes advantage of this effect. It
allows you to choose whether your speakers will play the full frequency range, or if the bass
will be redirected to the subwoofer. The advantages of redirecting the bass to a subwoofer
include the following:
• The overall bass of the system is improved as subwoofers are specially designed for this
frequency range.
• The subwoofer can simultaneously play the bass from all of the speakers, in addition to it’s
own low frequency effects channel (LFE).
• There is no loss in perception of the position of movie or music sound effects, as the ear
cannot easily locate the position of low frequency sources.
• Smaller speakers can be used for main front, center and surrounds, as they do not have to
reproduce the low frequency range. This leads to a saving in speaker expense and room
space. A subwoofer is required if the front speakers are set to SMALL.
• Your amplifiers do not waste power reproducing the low frequency range when using a
powered subwoofer. Nearly all home audio subwoofers are self powered.
See page 60 for information regarding the adjustment of the bass management crossover
point. Note: The SPEAKER SIZE menu is used to set the bass management correctly for your
speaker system. See pages 56-57.
Dolby Digital and DTS modes are designed especially for complete systems with front, center,
and surround speakers and subwoofers. You need all of the speakers to get the best perfor-
mance from your Home Theater. If you do not have a subwoofer connected, then you should
not use the bass management system (so set all the speakers to Large). Without a subwoofer,
you will be missing the 5.1 LFE (low frequency effects) information.
Considering the advantages of the bass management system, you might try setting all of your
speakers to Small, even if they are capable of good low-frequency performance.
