In installations, Chaos provides the best sound quality of any intercom available. On tour, its durability, dependability and easy hookup have made it the standard of the touring lighting and sound industry.
Standard microphone cable connects the power supply and the beltpacks. Regular beltpacks have one male and one female XLR connector to facilitate daisy-chain hookup. This allows you considerable flexibility in laying out cable.
The Chaos system is designed to work best with the Beyer Dynamic DT108/109 headset. A 4-pin male XLR connector is used on the headset for connection to the beltpack.
Power supplies are available in portable and rackmount styles for both 120 volt and 240 volt operation.
The mic switch is either a momentary or an alternate action switch at the customer's option. Some types of stations are available with an electronic mic switch to permit field selection between alternate action and momentary mode.
Signalling stations use a call light to indicate signalling. Signalling stations do not require additional cabling; they run on the standard 3-wire mic cable used by the rest of the system. If an audible signal is desired, "beeper" stations add an audio tone.
Beltpacks
are housed in rugged, die-cast aluminum boxes with sturdy beltclips. A
lighted signalling beltpack is illustrated. Beltpacks are the most popular
packaging option of our stations. They are most commonly used by persons
who are standing or moving around during their use. Of course they can
also be used by persons who are running consoles.
Rackmount units bolt into standard 19" racks. A signalling rackmount station is shown. Audio effects racks, dimmer racks, etc. are popular uses for rackmount units.
combine the ability to hear communications at a distance with portability.
The unit is self-contained and has a handle for easy carrying. This makes
it very attractive for touring use, or for use in installations where flexible
location is important. Talkback is done via a CB-style mic, or by a headset.
When used with a headset, the speaker may be turned off if desired.
Custom packaging options are available. Please contact the factory.
The PS301 is a 46 volt DC power supply rated for continuous operation. It is protected by foldback current-limiting against damage by shorting. The power supply also provides the audio line termination circuitry for the Chaos intercom system.
The portable power supply is available for 120 volt or 240 volt use. The 240 volt model has a transformer capable of being rewired for either voltage. Rackmount power supplies are switch selectable between 120 volt and 240 volt operation.
Power supplies have four 3-pin female XLR output connectors for hookup to the stations.
Either portable or rackmount housings can be ordered. All models can be ordered with dual talk channel outputs for 2-channel communication.
An optional test tone is available for assistance in setting up the system. When switched on, the test tone emits a continuous tone into the system allowing one person to check any station. This can be very helpful in touring situations.
Please consult the factory regarding systems of more than 30 stations.
The DT108 is a one muff unit; the DT109 has two muffs.
While other headsets of the correct impedance and other specifications will work with the Chaos system, we recommend the DT109/108.
Telephone style handsets are available. These are useful for locations where a traditional headset would be unwieldy. Handheld and gooseneck mounted microphones are also available. These are often used with speaker stations instead of headsets.
If the wired intercom and the wireless radios serve two separate functions, say lighting and security, all is well. But what do you do if you need to intercommunicate? Until now the only choice you have had is to use expensive wireless headset systems that support very few stations.
The Goddard Design RADIO-CHAOS INTERFACE allows communication between Motorola Radius-series radios and Chaos 301 intercom systems. The interface turns any one of several types of Motorola radios into a Chaos to radio "base station".
