6.45.1.2. Centre Width
The Centre Width controls the width of front centre sound in the perceived sound image when listening to
up-mixed audio. It mainly affects the perception of speech and dialogue. Narrower centre width will cause
the front centre sound primarily coming from the centre speaker. Wider centre width causes the front
centre sound comes from the centre, left and right speakers. To adjust the centre width of the up mix
control, drag the slider right to increase the value of the centre width or drag the slider left to decrease the
value of the centre width. The value range is 0 to 7 in increments of 1. The default value is 3.
6.45.1.3. Surround Depth
The Surround Depth controls the depth of surround sound in the perceived sound image when listening
to up-mixed audio. More sound will be directed to the front speakers (centre, left and right speakers) if a
shallower surround depth is selected. If a deeper surround depth is selected, more sound will be shifted
to the surround speakers. To adjust the depth of the surround, drag the slider right to increase the depth
or drag it left to decrease the depth. The value range is 0 to 7 in increments of 1. The default value is 3.
6.45.1.4. Surround Delay
This Surround Delay controls the amount of time that the surround sound will be delayed against other
channels. Proper amount of surround delay will provide a good perception of surround sound. To adjust
the delay of the up mix surround, drag the slider to the right to increase the delay or drag it to the left to
decrease the delay in milliseconds.
The value range is 4 ms to 20 ms in increments of .021 ms. The default value is 10 ms.
6.45.1.5. LFE Gain
