The MA125 is the most easy and universal 100 volt
professional mixing amplifier for commercial and
industrial applications. This amplifier is very intuitive to
use because it has only the buttons available you really
need. MA125 can drive 8 ohms or constant voltage
loudspeakers.

4 microphone inputs with integrated speech filters, 4
selectable line inputs and one emergency line / telephone
input are available where MIC input 1 is meant to be the
main microphone paging input. The MA125 allows you to
have priority with your paging microphone as well as a
seamless mix of your microphone with your sound
source.

MA125 has a 3-level priority system where the
emergency line / telephone input at the back have the
highest priority.

MIC1 has the second priority level and the third priority
level can be activated by a dry contact at the back of the
amplifier that mutes all background music inputs and
activates the integrated chime. Further the MA125 is
supplied with detachable 19” brackets.

When needed the signals mixed via the MA125 mixing
amplifier can be recorded or distributed via the record
output. You can even insert external signal processors or
use the MA125 as a pre-amplifier in combination with an
external power amplifier.
