6. CINEMA EQ (Adjusting the tonal balance of speakers)
It is difficult to balance tonal quality of the main, center, front effect
and rear effect speakers, because they may be different in type and
size, and their setting positions and heights are also different. The
built-in CINEMA Equalizer enables you to balance tonal quality of the
speakers easily by adjusting tonal quality of the main/center, front
effect and rear effect channels individually.
This is also useful to compensate for loss of tonal response of the
main and center speakers when those speakers are placed behind
the projection screen (if you use a projector in place of a TV).
The CINEMA Equalizer consists of the High-shelving equalizer
(HIGH) and the Parametric equalizer (PEQ). The High-shelving
equalizer changes high frequency characteristics smoothly, and the
Parametric equalizer boosts or cuts any selected frequency smoothly.

PEQ: FRQ ................ Selects a frequency you will boost or cut.
GAIN ......................... Adjusts the equalizing level on the selected

* Adjustment can be made by monitoring sounds using the test-
tone. To use the test-tone, press the TEST switch so that
“TEST DOLBY SUR.” or “TEST DSP” appears on the display.
The test-tone is fixed on the channels on which you make an
adjustment and output from the corresponding speakers.
It is recommended to make these adjustments together with the
tonal quality adjustment of the center speaker on the function “5.
CENTER GEQ”.
NOTE: Excessive increase of the GAIN level may cause an overload.
It is recommended to adjust the GAIN level so that it becomes lower
than the preset value.
