WMS 4000 Multichannel System Schematic & Part List 1-32 Channel MCS0802001 Wolfgang Fritz / Feb. 2008 1 Introduction 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 for a standard system to be installed, please do not hesitate to contact us under support@akg.com. All the WMS450 Systems in this document are designed with active antennas that can used in all venues with a 20m RG58 antenna cable. SRA2 B/W active directional antenna For Venues (tour sound &installs) that cover large distances (up to 150m, 500 ft) 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/330 ft free line of sight. Ideal for conference rooms, multi purpose halls, houses of worship etc. MCS0802001 Wolfgang Fritz / Feb. 2008 2 Content General Information Receiver/Antenna Placement Squelch Intermodulation HUB4000Q - HiQnet System Architect Cable Attenuation PS4000 dip switch AB4000 dip switch PS4000 dip Switch Matrix Required Component Matrix Glossar WMS System 1 Channel 1 Channel 2 Channel no PS4000 2 Channel no PS4000 2 Channel 2 Channel 4 Channel no PSU4000 4 Channel no PSU4000 4 Channel 4 Channel 5 Channel 5 Channel 6 Channel 6 Channel 8 Channel 8 Channel 9 Channel 9 Channel 10 Channel 10 Channel 12 Channel 12 Channel 16 Channel 16 Channel 24 Channel 24 Channel 32 Channel 32 Channel Antenna Type SRA2 B/W RA4000 B/W SRA2 B/W RA4000 B/W SRA2 B/W RA4000 B/W SRA2 B/W RA4000 B/W SRA2 B/W RA4000 B/W SRA2 B/W RA4000 B/W SRA2 B/W RA4000 B/W SRA2 B/W RA4000 B/W SRA2 B/W RA4000 B/W SRA2 B/W RA4000 B/W SRA2 B/W RA4000 B/W SRA2 B/W RA4000 B/W SRA2 B/W RA4000 B/W SRA2 B/W RA4000 B/W Information Information Information Information Information Information Information Information Information Information Page 4 4 4 5 6 6 6 7 8 9 Page 10 12 14 16 18 20 22 24 26 28 30 32 34 36 38 40 42 44 46 48 50 52 54 56 58 61 64 67 Schematic / Part List Schematic / Part List Schematic / Part List Schematic / Part List Schematic / Part List Schematic / Part List Schematic / Part List Schematic / Part List Schematic / Part List Schematic / Part List Schematic / Part List Schematic / Part List Schematic / Part List Schematic / Part List Schematic / Part List Schematic / Part List Schematic / Part List Schematic / Part List Schematic / Part List Schematic / Part List Schematic / Part List Schematic / Part List Schematic / Part List Schematic / Part List Schematic / Part List Schematic / Part List Schematic / Part List Schematic / Part List MCS0802001 Wolfgang Fritz / Feb. 2008 3 Technical Information Wireless Basics Every wireless microphone system has to operate on one specific frequency Transmitter and receiver of a system need to work on the same frequency Two transmitters cannot be used with one receiver at the same time Receiver/Antenna Placement Direct line of sight between transmitter and receiver antenna Place the receiver/antennas at least 5 ft. (1.5 m) away from all transmitters Place 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. Do not place the antennas in hidden places (behind walls) 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 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 Advanced: Tone Code (only WMS4000) ­ The audio turns on only in the presence of the correct tone code and an adequate signal strength (-100dbm) ­ Lock out 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. In your case this intermodulation products are generated in the bandwidth that you are using. To avoid intermodulating frequencies, we offer you pre-calculated frequencies as presets in the SR450 and SR4000 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 at your venue. MCS0802001 Wolfgang Fritz / Feb. 2008 4 HUB 4000 Q The HUB 4000 Q adds HiQnet functionality to an AKG wireless system (SR 4000, SST 4 and upcoming devices are supported). For large wireless systems multiple HUB 4000 Q's can be used and controlled from a single computer. With connecting the HUB 4000 Q to a HiQnet network the user is able to monitor and control an AKG wireless system from a computer running System Architect. HiQnet System Architect The simple and easy to use user interface of the HUB 4000 Q plug in within System Architect allows the user to setup and configure the wireless system easy and fast with tools like Auto Setup, Environment Scan, RF Monitor and Device Manager. HiQnet System Architect also allows custom configuration of custom made user interfaces which makes it a perfect tool for installed sound and tour sound applications. Today's HiQnet system is built from flagship products from Harman Pro brands AKG Acoustics, BSS Audio, Crown International, dbx Professional, JBL Professional, Lexicon Pro, Soundcraft and Studer. AKG User Interface Features automatic identification of all HUB4000Q's Simple and easy to use channel-oriented user interface Fast and intuitive setup and configuration of frequency management with Auto Setup, Enviroment Scan and Device Manager Device Manager ­ Frequency Management Offline configuration Save and load your setup Enviroment Scan - Frequency Graph MCS0802001 Wolfgang Fritz / Feb. 2008 5 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 and WMS4000, 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. RG58 Cable Attenuation (MKPS, MKA5, MKA20 antenna cable) PS4000 dip switch This dip switch reduce the input RF level of the PS4000 between 0 dB and 14 dB. All antenna output level and the cascade(link) output level have an effect on this reduction. PS4000W ­ Power Splitter Rear View Antenna A cascade output Antenna A input Ant. B (DC power) 4x Antenna A output (DC power) Signal level adjustment Attenuation dip switches behind AKG Logo AB4000 dip switch The AB4000 has a fix 17.5dB amplifier in the output stage. The dip switch reduce the input RF level of the AB4000 between 0 dB and -14 dB. AB4000 get the DC power through the antenna cable from the PS4000 or an ASU4000 unit.
