WMS450/470 MULTICHANNEL SETUP GUIDE SCHEMATIC & PART LIST 1-16 CHANNEL

Introduction
SRA2 B/W active directional antenna
For venues (tour sound &installs) cover a large area (up to 150m, 500ft) like music halls,
stadiums and other open air applications.
RA4000 B/W active omni-directional antenna
For venues without a designated transmitter area and up to 100m/330ft (free viewing
direction). Ideal for conference rooms, multi purpose halls, houses of worship etc.
The following schematics will help you to easily set up multi channel systems.
Please use the equipment that is specified in the schematics only.
For your convenience and understanding, we’ve added technical information and part lists.
You can use this part lists when ordering the system you require! If you need any help
regarding the frequency regulations or if your particular situation doesn’t allow the installation
of a standard system, please do not hesitate to contact us at [email protected].
All the WMS450/470 systems in this document are designed with active antennas that can
be used in all venues with a 20m RG58 antenna cable.

Technical Information
Wireless Basics
Ø Every wireless microphone system has to operate on one specific frequency
Ø Transmitter and receiver of a system need to work on the same frequency
Ø Two transmitters cannot be used with one receiver at the same time
Receiver/Antenna Placement
Ø Direct line of sight between transmitter and receiver antenna
Ø Keep the receiver/antennas at least 5 ft. (1.5 m) away from all transmitters
Ø Keep the receiver antennas at least 5 ft. (1.5 m) away from any big metal object, wire
(particularly wire mesh) or sheet metal structures, walls, ceilings, etc.
Ø Do not place the antennas in closed areas (behind walls)
Ø Place the receiver at least 5 ft. (1.5 m) away from any equipment that may emit RF
radiation such as lighting racks, fluorescent lamps, digital effect units, or PCs
Squelch
Ø Standard: Carrier squelch, manual
–Operates strictly on the signal strength of the signal.
–If received signal strength drops under the adjustable squelch threshold the
audio output is muted
Ø Advanced: Tone Code (only WMS470/4500)
–The audio turns on only in the presence of the correct tone code and an
adequate signal strength (-100dbm)
–Lock out of all signals except ones with the correct key.
Intermodulation
Intermodulation is the result of two or more signals of different frequencies
being mixed together, forming additional signals that are not harmonic
frequencies of either.
By using more than one transmitter simultaneously at the same location,
intermodulation happens in the receiver and/or transmitter. These
intermodulation products are generated in the bandwidth that you are using.
To avoid intermodulating frequencies, we offer pre-calculated frequencies as
presets in the SR450 and SR4500 Receiver. Please, make sure that when setting
up a multi channel system, all your receivers are set to the same country preset
(NAME) and group. Use the automatic channel function (auto setup) to scan for
free frequencies in your venue.

RG58 Cable Attenuation (MKPS, MKA5, MKA20 antenna cable)
Cable Attenuation
To obtain the best sound possible, you need to have the right RF input level throughout
your signal chain. Premium quality wireless systems like the WMS450/470 and
WMS4500, offer you adjustable RF-level settings that garantee to maximise operating
distance even when using different cable lenghts and different types of cable! For this
purpose, AKG’s PS4000W antenna splitter, has 3 dip switches that you’ll find on the right
side of it’s front panel, behind the AKG logo.
PS4000 W dip switch
These switches reduce the input RF level of the antenna input between 0 dB and 14 dB.
Levels of all antenna outputs and the cascade (link) output will be reduced.
AB4000 dip switch
The AB4000 has a fix 17.5dB amplifier in the output stage. The dip switches reduce the
input RF level of the AB4000 from 0 dB and -14 dB. AB4000 gets the DC power from the
PS4000W or an ASU4000 unit via the antenna cable

You have to use these PS4000 W dip switch settings for all PS4000 W directly
connected to antennas.
All PS4000 W connected to a PS4000 W link output (cascade)
have dip switch setting ON/ON/ON (0dB)
