POWER LED
The individual equalization faders adjust the gain or loss at each
filter frequency. There are 31 of these faders per channel on the
ULTRAMIX3102-EQ. By adjusting a combination of faders, an overall
frequency response can be developed and the physical position of
the faders will give an approximate visual indication of this response.
2
EQUALIZATION
The gain control adjusts the overall gain of the equalizer when
the EQ switch is “in”. It is generally used to compensate for level
changes due to the equalization process, but can also adjust overall
system level and gain structure. Overall gain with this control is from
+6dB to -∞.

On the ULTRAMIX3102-EQ, a 10-segment, two color LED level
meter indicates the output level of the equalizer. A Clip indicator LED
illuminates when any point in the equalizer signal path reaches a
level within 3dB of clipping.
4
LEVEL METERS
This switch selects the operating range of the individual equalization
faders between 15dB and 6dB. The 15dB settings should be used
when this much equalization is needed. The 6dB setting allows finer
resolution on the fader settings.
5
RANGE SWITCH
This switches the Graphic Equalization and gain adjustments,
allowing the effect of any equalization to be compared to a “flat”
response. This switch does not defeat the High-pass filter.
6
EQ BYPASS SWITCH
The high-pass filter can be used to supplement the frequency
response achieved by the bandpass filters. Its function is to “roll off”
the response below a given frequency eliminating subsonic inter-
ference like wind noise or floor rumble. This frequency is adjustable
between 12Hz and 285Hz.
