Figure 75. Dividing the Left Channel
There is one configuration for each of the channel pairs, and a separate configuration for the center
channel. There are four configurations for speakers or speaker pairs that can be made:
1. Center Speaker
2. Left Front, Right Front
3. Left Surround and Right Surround
4. Rear Left Surround and Rear Right Surround
Single Subwoofer
A bass management configuration with a single subwoofer will mix the low frequency of all crossover
channels with the subwoofer. You can select which speakers to cross by assigning them to be “small”
speakers in the bass management configuration setup screens.
Multiple Subwoofers
When there is more than one subwoofer channel assigned using bass management the LFE channel is
evenly mixed between all of the subwoofer channels.
Each subwoofer channel is assigned location information to specify Left, Right, and Front, Back
positioning. This has significance so that channels that are crossed with the subwoofers would have the
low portion directed only to the closest subwoofer. Speakers on the left will be crossed with the left
positioned subwoofer while speakers on the right are crossed with the right positioned subwoofer. The
center speaker would be crossed evenly between left and right subwoofers. Front speakers are crossed
with front subwoofers while surrounds are crossed with back subwoofers.
Subwoofer Audio Processing
Each subwoofer channel from the bass management output can be adjusted downstream the same as
other channels. The downstream processing includes Dirac filters, 1/3 octave EQ, Parametric EQ, output
channel routing, and high pass /low pass filtering.
No Subwoofers
When there is no subwoofer installed, the LFE can be mixed with any of the channels that have speakers
large enough to handle the low frequencies.
