Trident A-Range EQ Controls

Phase
Three low pass filters are available, and they can be used simul-
Low Pass Filters
taneously in any combination. The available cutoff frequencies
are 15 kHz, 12 kHz, and 9 kHz with a slope of 12 dB per oc-
tave. Each filter is active when its button is engaged (darker).
Each low pass filter "adds" to the others. For example, engaging
the 15K filter will rolloff frequencies above 15 kHz, but engaging
9K as well will also attenuate frequencies above 15 kHz, even
more than if 15K was used by itself.
