AMK SPEAKERS: THE INNOVATORS OF SELF AMPLIFIED SPEAKERS

AMK DS84-B
DS84-B-X (AES67 Compatible)

1 active and 3 passive

Dante network enabled speaker set

Channels (zones): 2

The AMK DS84-B 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.

One PoE+ amplified speaker can power a total of (4) speakers, including (3) additional passive speakers, with (2) speakers per audio zone.

This assembly can be used in wide range of projects for paging and background music applications. The DS84-B is ideal for hotels, education, hospitals, retail stores, performing art centers, restaurants, airports, houses of worship, and board rooms.

AMK Dante Ceiling Speaker Advantage
* No need to have separate dante enabled amp or I/O interface * A Single RJ45 connection to main active speaker with two conductor wire connection to each of the three passive speakers with separate channels. * Highly efficient speaker driver due to barium ferrite magnet. * Cost effective simple one system solution. * 2’ x 2’ ceiling tile lay in system for fast and easy installation and visually attractive for tile ceiling environment
