MDS Series Digital / Analog Radio Loudspeakers
The MDS-1400/2400/3400 Series are wireless, programmable, receive-only radio speakers that can be used with any Analog or DMR Digital (DMR Tier2 TDMA) portable or mobile radio programmed in the UHF band (400-470MHz) for remote broadcasting & announcements. System will allow a user with a portable radio within range to transmit audio from their radio to one speaker, a select number of speakers, or all speakers within a building/area.
The speaker system consists of the speaker and a Bluetooth USB module for your PC that is used to program the speaker. The MDS Series uses a plug-in power supply that converts the AC voltage to 12VDC to power the speakers. MDS-1400/2400 versions can be either wall-mounted or stood on a book shelf. The MDS-3400 is a circular speaker that is hard mounted into a wall or ceiling.
Use wherever wireless broadcasting or announcement loudspeakers are needed but where it may be hard to install wiring for a PA system: Schools, Factories, Bus/Train Terminals, Shopping Centers, Large Stores, Parking Lots, Golf Courses, Amusement Parks, Warehouse & Distribution Centers, and Public Address Alerting. The plug and play design means there is no installation of pulling wires through walls thus reducing costs and saving time.
Visual Diagram of MDS Speaker use within a building:
When using in DMR Digital, each speaker has a unique ID (OWN ID) that is used to identify each speaker. It allows the portable radio to select that specific speaker for volume control, or to broadcast to that specific speaker only. For a visual example, using the figure above you could program your portable DMR radio to speak to all the rooms with a speaker at once, or just a few speakers at a time (Program your portable radio to broadcast only to Room #6 & #2).
For Analog radio set-up, you will need to program CTCSS/DCS codes along with your radio frequency in specific speakers for privacy and also to differentiate between speakers when transmitting.
