1. What are the MDS-1400/2400/3400 Series Speakers?
MDS-1400/2400/3400 are wireless, programmable, receive-only speakers that can be used with any Digital
(DMR Tier2 TDMA) radio programmed in the UHF band (450-470MHz) for remote broadcasting. System
willallow auserwith aportableor mobileradio withinrangeto transmitaudio from their radio to onespeaker,
a select number of speakers within a building/area, or several speakers at once.
Speaker system consists of the DMR Speaker and an optional Bluetooth USB module for your PC that is
used to program the speaker. The MDS-1400/2400 versions have a built-in power supply and wall plug
(AC110V) so they can be either wall-mounted orstood on a book shelf. The MDS-3400 is a circular speaker
that is hard mounted intoa wall or ceiling with a plug-in power supply option to allow for either a wall plug or
wire installation.
Use wherever broadcasting loudspeakers are needed but 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.
Figure (1-1) shows basic use of the MDS speaker with a portable radio.

3. Operation
3.1 Power ON
Operation is as easy as plugging in the speaker. Speaker will turn on automatically about 30 seconds
AFTER they are plugged into your power source (AC110V), at which point a bell chime will sound as
the speaker has powered on and entered “Stand-by Mode”. The switch on the bottom of the MDS-
1400/2400 rectangle or side of the MDS-3400 circle speaker is used to turn on/off only the back-up
battery. Leave this switch in the “ON” position so that the battery charges during use unless you need
to turn off the battery for transport. Each speaker will stay on & be ready to receive until the speaker is
unplugged or the backup battery is drained.
3.2 Volume Control
Volume for the speaker itself is pre-set by the speaker’s PC programmer through the PC Programming
Dongle, or can be adjusted over the air with a Maxon MDP-6424 portable radio. (Contact your local
Maxon dealer for more information)
3.3 How it works
Each MDS Series speaker is a UHF band “Receive-only” DMR Tier II digital radio. Your two-way radios
and the MDS speaker need to be programmed to be on the same UHF band radio frequency and Color
Code before using (Contact your local Maxon dealer for programming help). Once both the portable
radio and the speaker are programmed, the user transmits audio to the speaker by talking clearly and
loudly through the portable radio (press and hold PTT button on the portable radio while talking). Audio
will broadcast through the wireless speaker as the portable radio transmits to the speaker and the sound
will turn off when the user stops transmitting (release PTT button to stop transmitting).

Figure 3-2) Visual Diagram of Speaker use within a building
Each speaker has a unique ID that is set in the radio programmer, this address is used to identify the
speaker when programming your portable radio. 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).
