Product Description (English):

The MA-1410B is a professional 10-channel preamplifier mixer designed for general PA applications. Whether for conference systems, paging setups, or emergency sound installations, this unit offers flexible signal routing, intelligent priority handling, and robust audio performance.

Each of the 10 inputs can be switched between MIC and LINE level and features signal LED indicators and phantom power (+15 V DC), allowing the use of both dynamic and electret condenser microphones. Inputs 7 to 10 also include RCA jacks for unbalanced line sources.

A built-in electronic chime (2-tone or 4-tone, jumper-selectable) can be triggered manually on the front panel or automatically via a paging microphone (e.g., VLM-100A via RJ-45). The chime includes its own volume control and priority logic over channels 4 to 10.

Each input can be assigned to Master Output 1, 2, or both using front-panel switches. Both master outputs feature individual volume controls, 2-band equalizers, and 5-stage LED level meters. A separate REC OUT is also provided.

The MA-1410B operates on 230 V AC or 24 V DC, making it ideal for systems requiring emergency power compatibility. Its symmetrical XLR connections and intuitive interface make integration and operation straightforward.
