968 Graphic EQ
969 Dual Graphic EQ
Dual mono 10 band graphic equalizer
PAUs: 3
The graphic equalizer is available as stereo (linked parameters for left and right) or dual mono
(independent controls for left and right). The graphic equalizer has ten bandpass filters per channel. For
each band the gain may be adjusted from -12 dB to +24 dB. The frequency response of all the bands is
shown in the Figure 1. The dual graphic equalizer has a separate set of controls for the two mono channels
(see Stereo Graphic Equalizer).
Figure 10-125 Filter Response of Each Bandpass Filter
Like all graphic equalizers, the filter response is not perfectly flat when all gains are set to the same level
(except at 0 dB), but rather has ripple from band to band (see Figure 2). To minimize the EQ ripple, you
should attempt to center the overall settings around 0 dB.
