PRODUCT OVERVIEW
The MLX20 is a professional two channel Mic
Preamplifier which also accepts Line levels and Direct
Instrument connection.
The unit is designed around an ultra low noise input
device with excellent common mode rejection
resulting in signal amplification of exceptional clarity.
The DI input circuit is FET based producing excellent
sonic characteristics especially on bass instruments.
Front panel controls include Input Gain, Variable High
Pass Filter and Output level control. Front panel
switches provide selection between the rear panel
Mic and Line inputs and the front panel DI socket.
Phase Reverse and +48V Phantom Power switches
are also included.
APPLICATIONS
The high degree of specification and performance the
MLX20 offers makes it the ideal preamplifier for direct
to analogue or digital recording of Mic, Line and
Instrument sources.
The MLX 20 may also be used as a high quality
active Dual DI unit.
