MA-4
NEW!!
Modern amplifier equipped with a DSP signal processor that enables precise correction of sound characteristics in objects with very challenging acoustic conditions. The amplifier activates only the microphones that are in use at a given moment, which eliminates the impact of ambient noise coming from unnecessarily open microphone channels. The amplifier is equipped with an MP3 player, a liturgical clock that switches between three presets according to previously programmed dates and times, and a “DE-ESSER” that eliminates sibilants during speech.
