Operating Manual - MQX-2310, MQX-1310, and MQX-2150 Graphic Equalizer
5.5 High-Pass Filter
The high-pass filter can be used to supplement
the frequency response achieved by the bandpass filters.
It’s function is to “roll off” low end response to eliminate
subsonic interference like wind noise, floor rumble, and
boomy microphone pops. The high-pass frequency on
the 31-band models is fixed at 40Hz with an 18dB/octave
slope. The MQX-2150 has an internally switched 20Hz
high-pass filter which can be disabled by a qualified ser-
vice technician.
5.6 Signal Present Indicator
A green LED indicates when input signal to the
equalizer is above -20dBu. EQ or Gain settings have no
effect on this indicator, as it only tells you the level of
signal applied to the equalizer.
5.7 Clip Indicator
The red Clip LED turns on when any signal within
the audio path e19dBu. Clipping can be detected
at the input stage, gain stage, or at the equalizer output.
5.8 Power Switch
This front-panel push-button switches the AC
power to the unit. The adjacent yellow LED indicates
when the unit is powered on. If the yellow LED does not
light, check to see if the unit is plugged into a live outlet.
If there is still no light, refer the unit to a qualified ser-
vice technician for possible fuse replacement.
