Safety First! • Read all documentation before operating your equipment. • Retain all documentation for future reference. • Save the carton and packing material even if the equipment has arrived in good condition. Should you ever need to ship the unit, use only the original factory packing. • Do not spill water or other liquids into or on the unit. • Make sure power outlets conform to the power requirements listed on the back of the unit.

1. APart MA200R Mixing Amplifier The MA200R is a professional 4 zone PA mixing amplifier for commercial and industrial applications. Rarely seen on its competitors, all microphone inputs have integrated speech filters and they are high-class transistor-balanced type, allowing good control of hum and noise over long cables. He’s able to drive 8-ohm or constant-voltage loudspeaker lines (50-70-100V).

No or distorted sound will be heard. This will be in case of overheating, being the result of drawing too much power from your amplifier, or the impedance of the speaker lines connected are below the minimum load impedance (see17).

The unit is shipped with the selector set to 230VAC. 16) Mains socket: The unit can be connected to the mains circuit by a standard IEC type power cord. This socket contains a 6,3AT, slow blow fuse. Use a screw driver to flip out the fuse compartment and to replace it by the same type.
24) CD stereo input, 500mV: Here you can feed a line level signal. You have to make your choice with the selector at the front (see 12). Stereo signals will be summed together. 25) AUX input, 500mV: Use this stereo RCA input to connect a line level source such as CD player, MD player, BGM computer, etc…. You have to make your choice with the selector at the front (see 12). Stereo signals will be summed together. 26) Line 4, 200mV / Mic 4 input.
4. Tuner Controls AM / FM mode switch Each time you press this button, the tuner will switch from FM to AM and the other way round. The actual radio band will be displayed at the left. Scan up / down By pressing “UP” or “DOWN” a few seconds, the tuner will start to search the next/previous radio station with sufficient signal (auto scanning). By just pressing “UP” or “DOWN” you work in manual mode. Each time you press, you change the frequency by 50 kHz for FM and 9 kHz for AM.
5. Inside Settings Phantom Power MIC1 : JP3 MIC2 : JP4 MIC3 : JP5 MIC4 : JP11 JP3 JP4 JP5 JP11 Phantom on / off jumper The MA200R has been shipped with these jumpers in the OFF position. For each microphone input a jumper is available. When you put a jumper to the ON position, phantom power will be supplied to the microphone input involved so you can use condenser microphones. In this case NO unbalanced jacks should be used! Phantom power does not damage dynamic balanced microphones.
6. Overview Of The MA200 Series MA200CDR • High quality 200 Watts 100 Volt mixing amplifier • Integrated 2-tone chime (adjustable volume) • Integrated AM/FM tuner and CD/MP3 player • 4 output zones.
7. How To Deal With 100V Loudspeaker Systems 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, not even one.
