DMS™ 2.1: Distributed Music System
Pragmatic’s DMS™ 2.1 allows you to give your customers an elegant distributed music system. It is very simple to operate, highly reliable and easy to install. The DMS™ 2.1 system delivers high quality audio at an affordable price. This simple yet elegant system provides unequalled sound quality with cable that runs to 3000 feet. It distributes audio signals to more than 32 listening areas using only a single category 5 wire. The cables can be home run into a patch bay or can be daisy-chained. DMS™ 2.1 finds applications in industrial and commercial installations including hotels, restaurants, sports bars, shopping malls, arcades, and theme parks.

The DMS™ 2.1 offers complete music distribution with paging solution on a cost effective category 5 wire. The in-wall amplifiers with volume control are locally powered (can be centrally powered on an 18/2 AWG along with the category 5 for signal) and daisy chained from one in-wall amplifier to another. Maximum of 32 volume-controlled amplifiers can be daisy-chain connected on a single category 5 wire. Further expansion is possible with additional repeater unit.

The system transmitter comes in a compact rack-mount enclosure. It has a built-in multi-channel audio switcher that can be controlled by an infrared remote control or a RS232/RS485 connection and a TPA™ transmitter to connect to the category 5 wire. A ba sic remote receiver in a single junction box connects to the category 5 wire to power the speakers directly. These include the TPA™ receiver, a rotary volume control, and the MBA™ high-performance, high-efficiency 24 Watt mono-block amplifier. The audio signal-to-noise ratio is about 96 dB, and has 20 KHz of audio bandwidth and less than 0.1% distortion. The unit operates on a standard 12 V DC power supply and has an operating temperature range of -40 to 85 degrees Celsius, so it can operate in harsh environments.

The DMS™ 2.1 uses Pragmatic’s proprietary SuperTranz™ circuit to eliminate any possibility of ground loops, AC voltage interference, noise pick-up, or hum introduction into the signal path. The DMS™ 2.1 works on category 5, category 3, and even unshielded telephone grade twisted pair wire. Despite using economical wires, DMS™ 2.1 is superior to traditional music distribution systems in performance and cost.
