Extron electronics SSP 200 - Back Speakers; Bass Management; Speaker Settings

SSP 200 • Speaker Setup 21
Back Speakers
Back speakers can only be enabled if the Surround L/R speakers are enabled. Speaker
enablement can be configured within the Speaker Configuration tab of PCS (see
figure37 on page41.
The drop-down list of the Speaker Configuration tab determines whether the audio
output channels for the back speakers are passed to the left back and right back (in 7.1
setups) or to a center back (in 6.1 setups).
To enable a configuration utilizing a center back speaker, the Center and Surround L/R
channels must be enabled, and the Height/Downmix channel must be disabled.
If the two speaker option is selected, then source formats with discrete or matrix mixed 6.1
encoded channels outputs the back channel signal to both the left and right back channels
equally.
By default, the back speaker option is set to 2 Speakers.
Bass Management
Low frequency sound is usually better handled by the subwoofer. Bass management
creates the subwoofer channel by separating the low frequency information from the satellite
speakers at a user-defined crossover point. This is summed with the Low Frequency Effects
(LFE) information encoded in the source format. When no subwoofer is present, subwoofer
content is sent to speakers set to Full Range (excluding the center speaker).
Speaker Settings
This feature sets bass management on or off for a particular speaker, defining the frequency
range output by that speaker (see figure37 on page41). These settings also enable or
disable the subwoofer and set the crossover frequency.
• Left and right front speakers and left and right surround speakers are set in pairs.
• The center speaker is set as an individual speaker.
• Back speakers can be set as a single speaker or as a pair of speakers, depending on
the system configuration.
Bass Management
Small speakers are those which are set to Bass Management. The output to each speaker
(other than the subwoofer) is limited to frequencies above the crossover frequency. By
default, center, surround, and back speakers are set to Bass Management.
Full Range
Large speakers are those which are set to Full Range. The full range of audio frequencies
from the audio source is fed through the output of each individual channel. By default, front
speakers are set to Large.
Subwoofer
This option allows the subwoofer to be enabled or disabled. When the subwoofer is
enabled, the signal contains filtered low frequency signals from speakers set to Bass
Mangement in addition to the LFE signal from the input source. If the subwoofer is disabled,
the LFE signal is mixed with the bass information of all speakers in the system that are set to
Large, except the center speaker.
