The AMK DS81-A-X is a Dante™ audio network addressable and self-amplified ceiling speaker system. The speaker is powered by PoE+ network switch meaning no external power supply is required.
The speaker includes a Class D amplifier which provides effective use of power. This system will solve the issue of having to provide a separate amplifier or I/O interface for speaker installations. The system comes with 8” coaxial 40W loudspeaker driver, CX802, that has excellent dispersion, wide bandwidth and a smooth frequency response makes this the top choice for today’s overhead commercial applications.
The audio network system is also compatible with AES67 and it is Dante Domain Manager Ready. Which makes this speaker system to be flexible with other audio network systems as well.
This assembly can be used in wide range of projects for paging and background music applications. The DS81-A-X is ideal for hotels, education, hospitals, retail stores, performing art centers, restaurants, airports, houses of worship, and board rooms.
