WELCOMETOBEHRINGER
Thank you for showing your confidence in us by purchasing the
BEHRINGER MICROMON MA400, a monitor headphone amplifier
that is both flexible and compact. On your headphones, you can
simultaneously listen to two audio signals:
Vone from a microphone
Vone from a mixer or a Hi-Fi unit
You can even emphasize one signal over the other. Hear yourself
sing, or concentrate on the main audio program. Both are
possible.
Please read the safety instructions that appear at the
end of this document.
