The MA200 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).
The amplifier has 4 microphone inputs, 4 selectable line sources 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 combo XLR3/jack or DIN 5 or euroblock connector at the back.
The MA200 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. Micro-
phone input 1 has the second priority level. With the control next to the XLR input, the vox (voice
activated) mute for microphone 1 can be activated and mutes all other signals, except the emer-
gency 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.
4 Zones can be individually switched on and off.
Compared to other zone amplifiers, the total load (200W) can be drawn in any combination from the
4 zones.
Zone 4 has an extra feature. Via the selectors at the front, you can choose whether this zone
receives back ground music only, messages only, both or none of them.
When any priority has been activated, 24V DC output (max.1A) will be available to activate priority
relays of loudspeaker attenuators or other devices.
When needed, the signals distributed via your MA200 mixing amplifier, can be recorded via the
record output.
19” Brackets are shipped along with your amplifier.
The MA200 is the all in one device to build larger 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 MA200 complies with the CE standards.
