Introduction
SRA2 B/W activedirectionalantenna
For Venues (tour sound&installs) thatcover largedistances (up to150m, 500 ft) like
music halls,stadiums and other openair applications.
RA4000B/W active omni-directional antenna
For Venues withouta designated transmitter area and up to 100m/330 ft freelineof
sight. Ideal for conference rooms, multi purpose halls, housesofworship etc.
Thefollowingschematics willhelpyou toeasily setup multichannelsystems.
Please use the equipmentthat isspecifiedin the schematicsonly.
For yourconvenience andunderstanding, we’veadded technicalinformation andpartlists.
You can usethis part lists whenordering thesystem you require! If you need any help
regardingthefrequencyregulationsorifyourparticularsituation doesn’tallowfora standard
system tobe installed, please donot hesitate to contactus under sup[email protected]om.
All the WMS450 Systems in thisdocument aredesigned withactive antennasthatcan
used in all venueswith a 20mRG58 antenna cable.

TechnicalInformation
Wireless Basics
Everywireless microphone systemhas tooperateon one specific frequency
Transmitter and receiver ofa system need to workonthe same frequency
Two transmitters cannot beused with onereceiver at the same time
Receiver/Antenna Placement
Directline of sightbetweentransmitter and receiver antenna
Place the receiver/antennas atleast5 ft. (1.5 m) away fromall transmitters
Place the receiver antennas at least5ft. (1.5 m) away from any big metal object,
wire(particularly wire mesh) orsheet metalstructures, walls,ceilings, etc.
Donot placetheantennasinhidden places (behind walls)
Place the receiver at least 5ft. (1.5 m) awayfrom any equipmentthat may emitRF
radiation such as lightingracks, fluorescentlamps, digital effect units, orPCs
Squelch
Standard: Carrier squelch, manual
– Operates strictlyonthe signal strengthof the signal.
– If received signal strengthdrops under the adjustablesquelch threshold the
audio output ismuted
Advanced: ToneCode (only WMS4000)
– The audio turnson onlyinthepresenceof the correct tonecode and an
adequate signal strength (-100dbm)
–Lock out all signals except ones withthecorrectkey.
Intermodulation
Intermodulationis the result of two or moresignalsofdifferent frequencies being
mixed together, forming additionalsignalsthat arenot harmonic frequenciesof
either.
Byusing morethanone transmitter simultaneously at the same location,intermodulation
happens in thereceiverand/or transmitter. In your case thisintermodulationproducts
aregenerated inthe bandwidththatyouareusing.
Toavoid intermodulating frequencies,we offer you pre-calculated frequenciesaspresets in
the SR450 and SR4000Receiver. Please, makesure that when setting up a multi channel
system, all your receivers are set to the same countrypreset (NAME)and group.Use the
Automaticchannelfunction(autosetup) to scan for free frequencies at your venue.

RG58 Cable Attenuation (MKPS, MKA5, MKA20 antenna cable)
Cable Attenuation
Toobtain the bestsound possible, you need tohave the rightRFinput level throughout
your signal chain. Premiumqualitywireless systems like the WMS450 and WMS4000,
offer you adjustable RF-level settings that garantee to maximise operatingdistance even
when using different cable lenghts and different types ofcable! For this purpose,AKG’s
PS4000Wantenna splitter,has 3 dip switches that you’ll find ontherightside ofit’s
front panel, behindtheAKG logo.
PS4000 dip switch
ThisdipswitchreducetheinputRF levelofthe PS4000 between0dB and14 dB.
Allantenna outputleveland the cascade(link) output level have an effect on this reduction.
AB4000dipswitch
The AB4000 has a fix 17.5dB amplifier in the output stage.The dip switch reduce the
inputRFlevel oftheAB4000 between0dBand -14 dB. AB4000 get the DC power
through the antenna cable from the PS4000or an ASU4000unit.
