NOTE:
Signal Connection
In a world of streaming compressed music, some low end frequencies are lost in translation compromising your
systems ability to perform to it's maximum potential. The MEMBX restores these lost frequencies returning
your system to peak performance during playback. The MEMBX offers high and low level inputs and a 9V output
allowing you to integrate the piece with a factory and aftermarket systems.
Bass Driver
: The MEMBX contains a bass driver circuit that accurately recreates and injects low frequency
information back into the signal path. This gives more bass impact to any audio saved in a compressed format.
Bass Equalization Circuit
: This feature accurately contours the restored bass to your speaker system.
Remote Control:
A mountable remote is included allowing you to adjust the effects of the MEMBX remotely. The
LED indicator grows brighter as you add more bass or dimmer when you decrease the amount of bass.
Bass Maximizer Indicator:
This indicator light on the MEMBX flashes when the bas maximization circuit is
activated.
For signal connection the output RCA connectors should be connected to the next component after the
MEMBX such as a crossover, equalizer or amplifier. Remember, the MEMBX should go inline before a crossover
