Resumen del manual
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 integrated radio, 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 .” TRS phone jack or via a combo XLR3/jack, DIN 5 or euroblock connector at the back. The MA200CDR 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 XLR 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. 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 MA200CDR mixing amplifier, can be recorded via the record output. 19” Brackets are shipped along with your amplifier. The MA200CDR is the all in one device to built 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 MA200CDR complies with the CE standards. Before using your MA200CDR, 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 are 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 MA200CDR, 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. We advise to use the back mounting holes as well; certainly in mobile racks. 14. Do not block the air inlets of the amplifier and see that sufficient cool air can be supplied. 15. Please check the units' condition after unpacking. If the outside of the carton box has been damaged, inform your shipper immediately. 16. Check all speaker lines for load charge (by APart wattmeter WM100) and short circuits, before connecting them to your amplifiers!
