The is a very compact, professional PA mixing amplifier for commercial and industrial applications. All MA125
microphone inputs have integrated speech filters. He's able to drive 8-ohm or constant-voltage loudspeaker
lines (50-70-100V).
The amplifier has 4 microphone, 4 selectable line inputs and one emergency/telephone input.
Mic input 1 is meant to be the main microphone paging input, for its signal can be fed via the front ¼” TRS
phone jack or via a XLR3, DIN 5 or euro block connector at the back. When needed, two APart paging
microphones can be wired in parallel on each mic input!
The MA125 has a . The emergency/telephone input at the back has the highest three level priority system
priority. Its signal goes directly to the main amplifier, bypassing any front control, and an attenuator next to
the input sets its level. Microphone input 1 has the second priority level. With the control next to the DIN5
input, the vox (voice activated) mute for microphone 1 can be activated and mutes all other signals, except
the emergency input. The third level can be activated via a dry contact (“priority over music”) and mutes all
background music inputs only. This contact activates the chime as well, only when a level has been set using
the “chime level” potentiometer.
When the priority contact has been activated, 24V DC (max.0,6A) will be available to activate priority 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.
19” Brackets are shipped along with your amplifier.
The is device to built professional industrial sound applications. You can insert an extra equalizer MA125 the
(such as the APart PXQ2215) into the signal path or add extra power amps (APart PA240P), using the pre
amp out/power amp in RCA connectors. When shipped a RCA bridge has been inserted.
The complies with the CE standards.MA125

1.Keep this manual for future reference.
2.Water and humidity are the biggest enemies of electric equipment. Operating it under moist conditions can even be
dangerous.
3.Clean only with dry cloth.
4.Do not operate near heaters or place it on other apparatus which produce a lot of heat.
5.Be sure your unit is always connected to the electrical safety earth. Do not defeat the safety purpose of a grounding- type
plug. If you have any doubt, please consult your dealer or a qualified technician.
6.Take care for the power cord. Never use a damaged power cord and install it in such a way that no one can walk on it.
7.Only use accessories specified by the manufacturer.
8.Distorted sound indicates that operating conditions are bad. Decrease the volume, check the speakers and
sources connected, or switch off the unit.

10. When smoke ore bad smell comes from your MA125, switch off immediately and disconnect from mains.
11. This apparatus should only be serviced by qualified personnel. If not, the warranty might be void.
12. Do not remove the cover panel. Removal of the cover will expose hazardous voltages.
13. Do not block the air inlets of the amplifier and see that sufficient cool air can be supplied.
14. Please check the units' condition after unpacking. If the outside of the carton box has been damaged, inform your
shipper immediately.
15. Check all speaker lines for load charge (by APart wattmeter WM100) and short circuits,
before connecting them to your amplifiers!
