MA125
The MA125 is a very compact, professional PA mixing amplifier for commercial and industrial applications. The MA125 can drive 8 Ohm or constant voltage loudspeakers.
The MA125 has 4 microphone inputs with integrated speech filters, 4 selectable line inputs and one emergency line / telephone input. MIC input 1 is meant to be the main microphone paging input. Its signal can be fed via the front jack or via the XLR3, DIN5 or Euroblock connector at the back.
When needed, two APart paging microphones (MIC-PAT-D) can be wired in parallel on each microphone input.
The MA125 has a 3-level priority system. The emergency line / telephone input at the back has 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. This dry contact mutes all background music inputs. It also activates the integrated chime. The level of the chime can be adjusted at the
back of the amplifier. Activation of the dry contact, releases a 24V output power? this can be used to switch the relays of loudspeaker attenuators or other devices.
When needed the signals mixed via your MA125 mixing amplifier can be recorded or distributed via the record output.
Further the MA125 is supplied with detachable 19” brackets.
The MA125 is the device to built professional industrial applications. You can insert an extra EQ (such as the APart PXQ2215) into the signal path or add extra power amps (e.g. PA240P), using the pre-amp out / power amp in RCA connectors.
