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.

    I absolutely refuse to read this excuse of the alleged printed word any farther. I am insulted by the fact that the printing is encoded. What kind of machine printed these words? You should be ashamed of yourselves​. Was this an attempt to somehow save money? Did you have any of your own employees try to read this aloud ? Get real!
