Speaker Bass Management -
This function enables Bass Management for the
Revolution 7.1 control panel. The Revolution 7.1 control panel uses Bass
Management to get the best sonic performance from your speakers. What this
means is that if you have large speakers, it will send the full-range signal to those
speakers. If you have small cube speakers, they probably can’t reproduce the
strong bass found in many DVD soundtracks, so the Revolution 7.1 control panel
automatically routes the bass from those speakers to the subwoofer.
Bass Management serves two purposes: 1. To allow a small-speaker surround
sound system to reproduce the full-frequency spectrum by re-routing bass from
the main channels to a subwoofer, which can handle frequencies that small
speakers can not. 2. As a precautionary safeguard to make sure the subwoofer is
not overdriven when it simultaneously receives both LFE & Crossover Bass. Enable
Bass Management by using your mouse to place a checkmark in the box, and use
the Crossover control to select how much main-channel bass is sent to the
subwoofer.
Speaker Size -
This setting tells the driver software what size your speakers are.
Select the speaker size that best describes your selected speakers: Large, (5” or
larger woofer), Medium (3”-5” woofer), or small (woofer smaller than 3”). There
are also settings for Cube or Flat Panel speakers. Click on the speakers in the
diagram on the left side of the window in order to set the sizes for each of your
speakers.
Crossover -
The Crossover control selects how much bass goes from the Main
speakers to the subwoofer and how much bass is retained by the main speakers.
When Bass Management is enabled, any sound above the Crossover threshold
is routed to the main channels (Front Left, Center, etc.). Any sound below this
frequency (or Crossover threshold) gets sent to the subwoofer. This is done so that
low bass frequencies don’t distort smaller speakers, and can improve the
acoustics of smaller rooms.
Your choices of crossover frequencies are 40Hz, 60Hx, 80Hz, 90Hz, 100Hz, and
120Hz. Check the documentation that came with your speakers to help you with
this setting. If you find a specification like, “Frequency Response: ±2dB 80Hz -
20kHz”, for example, set the crossover to 80Hz or higher. The Bass Management
box must be checked to use the crossover feature.
Link Stereo Output Levels -
This links the front left and right output level controls,
so that if you change one, the other follows.
Levels -
These controls change the volumes of the selected speaker outputs
independent of the other speakers. Move it to the right, towards 0dB, for more
volume or down towards -60dB for less volume. This is the same control found in
the Output Mixer, described in the next section.
Distance -
These controls change the volumes of the selected speaker outputs
independent of the other speakers. Move it to the right, towards 0dB, for more
volume or down towards -60dB for less volume. This is the same control found in
