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.
