The Apart MA125 is a compact, professional PA mixing amplifier for commercial and industrial applications. Rated at 120 watts and can be used on 8 ohm or 100 volt line systems.
Featuring 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.
If required, 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. There is also a 24VDC output for switching override relays such as attenuators or other devices and a record output.
Supplied with rack mounts.
