By pressing this button you will activate a 75 Hz
low frequency filter with a slope of 18 dB per octave.
You can use this facility to reduce the hum noise
infected by the mains power supply, or the stage
rumble while using a microphone.
This control is provided with 2 different indications: One is for the MIC and the
other for LINE levels. When you use a microphone, you shall read the MIC ring
(0~-45dB); when you use a line level instrument, you shall read the LINE ring
(+15~-30dB). For optimum operation you shall set this control in a way that
the PEAK LED(18) blinks only occasionally in order to avoid distortion on the
input channel.
When you use a line level instrument, you shall read the ring (+20~-20dB).For
optimum operation you shall set this control in a way that the PEAK LED(18)
blinks only occasionally in order to avoid distortion on the input channel.
This LED will help you to detect the input level
immediately. In this case the research of the
fault will become much faster!
