This professional booster makes it possible to amplify two balanced microphone signals to two balanced line signals.

• With the MB-22 its possible to work with two microphones, but you can also work in a stereo position.
• The gain of the MB-22 is switchable between 20 db and 40 dB, so you can use many kinds of microphones.
• With a low noise of +117 dB, a low distortion of 0,01% and the dynamic range of 129dB, you can be assured of a high quality sound signal.
• The MB-22 is also provided with a low cut switch, to filter disturbing signals in the sub-low, below 80 Hz. Of course, it is also possible with the MB-22 (like MB-11) to reserve unbalanced microphones signals over a long distance to balanced line-signals.
• The extremely low output-impedance of 1W makes it possible to use nearly any kind of line-input.
• The power supply of the MB-22 can be provided with a 9 Volt battery or an external power-adaptor, which has to operate between 9 and 24 Volt D.C., for example the Prefer EPS-12.
