The MA125 is a very compact, professional PA mixing amplifier for commercial and industrial applications. All

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 three level priority system. The emergency/telephone input at the back has the highest

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 MA125 is the device to built professional industrial sound applications. You can insert an extra equalizer

(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 MA125 complies with the CE standards.

Important Safety Instructions

Before using your MA125, take a few minutes to read these instructions carefully. This little time can avoid a

lot of headaches afterwards.

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.

9. Disconnect the unit from the mains power supply, when you do not use it for a longer period.

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!
