Toa A-3624D 240-Watt Digital Mixer Amplifier

The TOA A-3600D series is a versatile PA amplifier designed for paging announcements and background music applications in environments such as schools, offices, and supermarkets. It comes equipped with four microphone inputs and three auxiliary inputs, along with a 2-channel zone selector for flexible audio distribution.The amplifier includes useful features such as volume control, priority function, chime function, and remote confirmation capability. It also supports a 2-channel input BUS system (BUS 1 and BUS 2) and incorporates signal processing functions for enhanced audio control. Overall, the A-3600D series offers a practical and efficient solution for multi-zone sound systems.
