Yamaha DSP-A970 - Manual (Page 27)

DESCRIPTIONS OF THE ITEMS
1. Selecting Center Mode (CENTER MODE NRML/WD/
PHNTM)
In Normal (NRML) position, any frequency below 100 Hz will be
divided between the main left and main right speakers. For this
reason even a speaker smaller than the main left and right speakers
can obtain a sufficient effect.
In Wide (WD) position, all range of frequencies for the center-
channel are output to the center speaker. Select this position if a
good quality center speaker is being used.
If not using the center speaker(s), be sure to select Phantom
(PHNTM) position, and the audio signals for the center channel are
output to the main speakers.
2. Adjusting Center Channel Graphic Equalizer (CENTER
GEQ)
The built-in five band graphic equalizer is used to tailor, over a ±6
dB range, the overall output frequency response of the center
channel. The five bands cover the complete audible sound spectrum
and are centered on 100 Hz, 300 Hz, 1 kHz, 3 kHz and 10 kHz
frequencies. Adjustment should be done to each frequency
individually.
