MB QUART MX-4 - Manual (Page 5)

MX-1 FEATURE DESCRIPTIONS
SUBWOOFER INPUT LEVEL:
Variable from 40Volts to 4Volts. This control is used to match the output signal level from your headunit.
PARAMETRIC BASS EQ:
An incredible feature that allows for you to select a specific frequency, select a level of boost, and determine
how wide the span of the boost will be.
- BOOST:
Variable from 0dB to +10dB. At 0, the PARAMETRIC BASS EQ is OFF.
- BANDWIDTH:
Variable from Narrow(all the way to the Left) to Wide(all the way to the Right). Narrow will focus on your
selected FREQUENCY of BOOST and bleed into less frequencies. As you turn the potentiometer to the right,
you increase the range of frequencies being boosted above and below your selected BOOST FREQUENCY.
- FREQUENCY:
Variable from 30Hz to 100Hz. Use your potentiometer to select the center FREQUENCY to be boosted with the
PARAMETRIC BASS EQ feature.
LOW PASS FILTER:
Variable from 35Hz to 250Hz. This filter features a 24dB per Octave roll off. This means that the LOW PASS
FILTER has a steep cut-off and allows for very precise tuning. The LOW PASS FILTER allows frequencies below
your selected setting to pass thru while cutting out frequencies above your selected setting.
SUBSONIC FILTER:
Variable from 15Hz to 35Hz. This filter features a 24dB per Octave roll off. This means that the SUBSONIC
FILTER has a steep cut-off and allows for very precise tuning. The SUBSONIC FILTER allows frequencies above
your setting to pass thru while cutting out damaging and unwanted frequencies below your selected setting.
SUBWOOFER OUTPUT LEVEL:
Variable from 1Volt to 9Volts. This control is used to adjust signal output voltage to your amplifier. Use caution
when adjusting the signal output to be provided to your amplifier as you can damage your amplifier if you provide
more signal than your amplifier is rated to handle.
