[. . . ] The test-tone is output from the center speaker(s). Adjusts the output level at the LFE (low frequency effect) channel. If the LFE signals are mixed with signals at the main channels to output them from the main speakers, only the level of the LFE signals are adjusted. CENTER DELAY (Adjusting the delay of center sounds (dialog etc. )) Control range: 0 ms to 5 ms (in 1 ms step) Preset value: 0 ms Adjusts the delay between the main sounds (at the main channels) and dialog etc. This is for making sounds from the left main, center and right main speakers reach your listening position at the same time by delaying the sound from the center speaker if the distance from the center speaker to your listening position is shorter than the distance from the left or right main speaker to your listening position. 38 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.
