EQ-2231 is a 2-Channel graphic equalizer housed in a
standard 2U 19" rack case. Each channel has 31 frequency controls with
centre click sliders and an overall rotary level control. Push button switches
provide channel bypass and low cut filter in/out, filter adjustable
40Hz-400Hz. A 7-Step LED baragraph on each channel
gives an indication of the level. The EQ-2231 has a separate 18V power
supply which ensures superior signal integrity and reduces mains
interference.
