the Center channel output.
Center Contour Threshold
Range: -25 to 0dB
Sets the Threshold point for the Contour Style to
be operating.
EQ
The EQ for the Center channel features four-
band parametric EQ with high- and low-pass
filters switchable between Notch, Parametric,
Shelving and Cut filters.
Basic operation
Select Freq, Gain or Type to access the same
parameter for the four EQ bands.
Select Lo or Hi to access the three parameters
for the individual EQ band.
Press Bypass EQ to bypass the entire EQ.
Bypass does not affect the selected Contour
Style.
Type Selector
Press Type and use faders 1 to 4 to select fil-
ter types.
For Lo and Hi filters select between filter
types: Parametric, Notch, Shelve and Cut.
For Mid 1 and Mid 2 filters select between fil-
ter types: Parametric and Notch.
