MDS Series Digital / Analog Wireless 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 at the same time.
The speaker system consists of the speaker and a Bluetooth USB module for your PC that is used to program the speaker. Each MDS Speaker has a plug-in power supply that converts the AC voltage to 12VDC to power the speakers & a 9-hour back-up battery for emergencies or portability to other locations. MDS-1400/2400 versions are portable with their own wall plug & can be either wall-mounted or stood on a flat surface (shelf/table). The MDS-3400 is a circular speaker that meant to be installed into a wall or ceiling.
Use wherever loudspeakers are needed: Schools, Factories, Bus/Train Terminals, Shopping Centers, Large Stores, Parking Lots, Golf Courses, Amusement facilities, Warehouse & Distribution Centers, and as a portable Public Address system for a portable or mobile radio. The plug and play design means there is no installation of pulling wires through walls, so you save time with the convenience of an all-in-one PA system and eliminate installation & maintenance costs with hard wiring.
Using multiple MDS Loudspeakers within a building:
When using in DMR Digital, each speaker has a unique ID (OWN ID). This allows a DMR radio to broadcast to that specific speaker only or select that specific speaker for volume control. So using the figure above, you can program your DMR radio to speak to all the rooms with a speaker at once (ALL CALL), one speaker (PRIVATE CALL), or a few speakers at a time (Broadcast only to Room #6 & #2).
For Analog radio set-up, program CTCSS/DCS codes along with your radio frequency in specific speakers for privacy and also to differentiate between speakers when transmitting..
