Sound Field Expander
The sound eld expander can be used for widening a stereo sound eld, boosting center sounds and
accentuating sounds from the left and right sides. The signal ow of the expander is shown below.
The left and right channels are processed
independently and split into four paths.
Igain: This sets the overall gain into the Sound Field Expander
and should be set to a level that does not produce distortion,
yet achieves adequate signal gain.
Tgain: Controls the level of the “T” path. The “Through”
path (T) is the direct unmodied sound. This gain setting
determines the amount of unprocessed signal that is mixed
into the nal output. When combined with the H Gain and M
Gain signals, various expander effects are achieved.
Lgain: Controls the level of the “L” Path. The “Low Pass
Filter” path (L) lters out frequencies above 200Hz. When the
Lgain is set low, the bass is cut and when it is set high the
bass is boosted. The result is similar to a “sub-woofer” effect.
. The L Gain setting will control the level of bass in the nal
sound and will not affect the directional effects.
Hgain: Controls the level of the “H” Path. The “High Pass Filter” path (H) lters
out frequencies below 200Hz. The expander is most effective on high frequency
signals, so this gain setting is critical to get the most effective expander effect.
