CHAOS AUDIO INTERCOM SYSTEM
A PRODUCT OF Goddard
Design Co.
The Chaos 301 series intercom offers a complete communications system
engineered
to perform under the most demanding conditions. The Chaos system
features
frequency response shaped for maximum clarity in human speech
reproduction.
This means unparalleled "listenability" whether your production needs
quiet
whispering or speech loud enough to compete with the loudest rock band.
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.
GENERAL SYSTEM LAYOUT
A Chaos 301 system uses our regulated 46-volt power supply to run up to
30 stations. For special applications that require more than 30
stations,
please consult the factory. Each station consists of a beltpack and a
headset.
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.
STATIONS
Chaos stations are available as beltpacks, rackmount units and desk top
boxes. Each single channel unit includes a microphone pre-amp with
on/off
switch, a headphone power amplifier with volume control pot and 3 XLR
connectors.
(A 4-pin female serves as the headset connector, and a male and female
3-pin wired in parallel allow for daisy chain station connection).
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.
Desktop units are housed in slope-fronted cases meant to sit
on flat surfaces. While this is not a popular option for touring,
installations
may find a desktop station or two to be very handy.
Dual channel stations have an additional switch for channel
selection. Dual channel stations have two 3-pin male connectors, one
per
channel. A splitter box is required to daisy-chain dual channel
stations.
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.
Speaker stations
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.
The DS pack is a further refinement of a dual channel
station.
This unit allows the user to listen to two channels at once, selecting
the mix with a pan pot. The user can choose to listen to either channel
alone. The user can speak on either or both channels; the mic switches
are field selectable to alternate action or momentary mode. The unit is
particularly useful to the user who needs to communicate with one group
of persons while monitoring or being accessible to another group.
Custom packaging options are available. Please contact the factory.
POWER SUPPLIES
The standard power supply will power up to 15 signalling stations (and
22 non-signalling ones). A heavy duty model will handle up to 30
stations
on one talk channel.
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.
HEADSETS
The Chaos 301 system was designed to use the Beyer Dynamic model
DT109/108
headsets. These headsets offer superior comfort, high reliability and
excellent
sound reproduction.
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.
SYSTEM INTERFACE UNIT
The 301CNV allows the user to interface a Chaos Audio intercom system
with
either a Clear-Com, Clear-Com compatible, or RTS system, without
sacrificing
quality operation of any system. The 301CNV may also be used to
assemble
very large Chaos Audio systems that require more than 36 stations per
talk
channel. It is a rackmount unit taking a single rack space. The 301CNV
provides an electrically isolated interface between two intercom
systems.
RADIO-CHAOS INTERCOM INTERFACE
Goddard Design's Chaos Audio intercom is the standard for clear headset
communication under difficult conditions. But what do you do when you
need
to maintain communication with someone who must roam freely? In the
past
many productions have given such people "walkie talkies". The standard
of quality for portable radios are the ones manufactured by Motorola.
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".
