- 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 excep 2
- 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 2
- When needed the signals mixed via your ma125 mixing amplifier can be recorded or distributed via the record output 2
- When the priority contact has been activated 24v dc max 6a will be available to activate priority relays of loudspeaker attenuators or other devices 2

- How to deal with 100v loudspeaker systems 3
- In fact working with 100v loudspeakers is rather simple when done in the right way each 100v loudspeaker has a 100v transformer which can be set to a certain power for example 1 5 3 or 6w as the example shows the sum of all loudspeaker settings should never exceed the amplifier s power specifications never use low impedance 8 ohm loudspeakers on a 100volt system even not one 3
- Mixing amplifiers mixing amplifiers 3
- More technically when your paging amp has a maximum output of 125 watts at 100v this means that the minimum impedance connecte d should be at least 80 ohm 100x100 125 to check your loudspeaker lines use a decent impedance checker example ap wm100 3
- Now you are ready to get the best result on distributing your music and messages to your audience your little giant is like a swiss knife which will astonish you and many others 3
