General description
The AC-M1 control unit is designed for use with the SR-M1 and SR-M2 floor monitor speaker systems.
This electronic control unit provides the channel divider to divide respective frequency range between the
speaker units, and can realize smooth phase characteristics in the speaker system, by according with the
phase in crossover frequency while correcting time lag for the divided frequency range each other between
the speaker units.
In high frequency range in combination with the compression driver and the constant directivity (CD) horn,
the horn equalizer employs to provide smooth phase and amplitude characteristics.
Limiter is provided to prevent the speaker units from over-driven and damage in respective frequency range
and not to arise power amplifier clipping.
Quality sound is realized by use of selected electronic parts as OP amplifier, condensers etc.
