Controls and Functions

5Range switch - When pressed in, the LED in the switch lights and the Equalizer sliders cut or boost each frequency area by up to 6 dB, allowing fine frequency curves to be set. When out (in the up position), the Equalizer sliders cut or boost each frequency area by up to 12 dB, allowing course control. The setting of the ±12dB switch also affects how Cut Only operates—see #3 on the previous page for more information.

6Power switch - Use this to turn the power on and off.

7Bypass switch - When not pressed in, the equalization circuitry is made inactive so that the signal pass- es through unaffected, regardless of the settings of the Equalizer or Level sliders. When pressed in, the LED in the switch and the sliders light green and the equalization circuitry affects the signal as per the setting of the front panel Equalizer and Level sliders (see #1 and #2).

8LOW CUT switch- When pressed in, the LED in the switch lights yellow and the variable highpass filter is applied to the signal. Using the Low Cut can be highly effective in removing rumble and other low fre- quencies.

9LOW CUT control- When the Low Cut switch is pressed in, the varable low cut control is active. You can adjust the point at which the low frequencies begin to roll off with a frequency range of from 15 to 200 Hz.
