MDS Series DMR 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 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.
