WARNING CAUTION! Keep this system away from rain and moisture! FOR YOUR OWN SAFETY, PLEASE READ THIS USER MANUAL CAREFULLY BEFORE YOUR INITIAL START-UP! SAFETY INSTRUCTIONS Every person involved with the installation, operation and maintenance of this system have to: be qualified follow the instructions of this manual CAUTION! Be careful with your operations.
Make sure that the amplifier is turned down, before turning the power on or off. So you can avoid supersonic frequencies, which could damage your speakers. Don't put your equipment next to TV, radio, etc., because of interference or distortion. If you connect other parts of the system, be careful of ground loops. The best way to avoid ground loops is connecting the electrical system ground to one central point ("star" system). In this case the mixer can act as a central point.
Description of the device Features The MPA-440 is a professional multi zone Public Adress Amplifier: • Four independent channels • One balanced XLR and one 6.3 stereo input socket • Five sets of gain, treble, bass and volume controls • Five groups VU meter for output level • Three XLR+1/4” TRS combo input and two RCA inputs • Telephone paging function and monitor output • Priority of MIC-1.
11. Overall output LED VU-meter This stereo 6 segment LED-meter indicates the level of the overall output signal. 12. Monitor button Use this button to assign one or more zones to the monitor output. 13. Zone volume. Use to adjust the volume level for zone 1-4. 14. Zone LED VU-meter. This stereo 6 segment LED-meter indicates the level of each zone. 15. Power LED. Indicates that the amplifier is turned on. 16. AC Power Switch. This is the main Power switch. Press to turn the amplifier on. Backpanel Fig.
23. Line out zone 1-4. Mono balanced/ unbalanced line out terminal for zone 1-4. 24. Common terminal Connect this terminal with the – terminal of your speaker(s). 25. 25V terminal. Connect this terminal to the + terminal of your 25V speaker(s). In case of using several speakers make sure all speakers are wired in parallel. The total power rating of the 25V-speakers for each channel should never exceed 40W. 26. 100V terminal. Connect this terminal to the + terminal of your 100V speaker(s).
Operation Installation Remove all packing materials from the IPS-MPA440. Check that all foam and plastic padding is removed. Secure the equipment into a 19" rack. Connect all cables. Connecting Power / Circuit Size Requirements. The actual current draw, the amplifier demands from the AC mains, depends on many factors (its load, output level or the crest factor of its program material).
Example 3: using the 8Ω output with two 4Ω speakers. High impedance outputs If using the 25V outputs, the 70V outputs or the 100V outputs, note that all speakers should be wired in parallel. The total power of all speakers summed together should never exceed the total power of the amplifier in a 25V, a 70V or a 100V system! Setup example Fig.
Connection Cables Take care of the connector cables, always holding them by the connectors and avoiding knots and twists when coiling them: This gives the advantage of increasing their life and reliability, which is always to your advantage. Periodically check that your cables are in good condition, that they are correctly wired and that all their contacts are in good condition: a great number of problems (faulty contacts, ground hum, discharges, etc.
