GENERAL INFORMATION
The MX3 is a universally applicable mono preamplier with 2 MIC and 1 LINE inputs (mixable).
Universal application, easy operation and high overload resistance characterize the MX-3.
The preamplier is equipped with highquality builtin XLR jacks (Neutrik), switchable phantom power for
condenser microphones and separate LF / HF sound control for each of the three inputs and master section.
Separate sound control ensures precise room equalization and perfect adaptation to room acoustics.
In addition, the MX3 has switchable phantom power 18 V, LOW / HIGH ONOFF jumper per mic input.
The output of the preamplier MX3 is transformer balanced with select jumper for 0 dB or +6 dB signal
setting, providing high noise immunity at +6 dB setting of the output, so that the signal feedback can be done
