Audiocom Intercom Systems

Why Choose Audiocom®

Telex products are designed and built using the

latest and most sophisticated processes available.

Audiocom intercom equipment employs superior

technology compared with other TW party line

intercoms. In a business where manpower, space

and cabling are at a premium, Audiocom

products provide users with a competitive

advantage by offering modular, open-ended

designs and unparalleled reliability. Systems start

with a 2 or 4-channel master station (MS2002 or

MS4002) and expand into convenient 4-channel

expansion panels (EMS4001), for up to 22

individual intercom channels.

Audiocom is unique among professional intercom

systems today. Audiocom intercom systems utilize

a technologically superior balanced audio

transmission configuration. The use of balanced

audio produces a variety of functional benefits,

including lower inherent system noise, immunity to

external noise sources such as RFI, dimmers and AC

power, and the ability to make substantially longer

cabling runs without special wiring.

The unique balanced audio design of Audiocom

intercom systems allows users the longest TW party

line cable runs in the industry; up to 3000 feet.

This is critical when installing large or widely

dispersed systems. The differential input/output

guarantees excellent audio quality, even under the

harshest conditions. Superior audio quality reduces

user fatigue and missed cues as a result of users

not wearing their headsets, or “tuning out” the

noise.

Audiocom utilizes a distributed amplifier system

structure. Each main or remote station houses its

own microphone preamplifier, headset or speaker

power amplifier and signaling circuitry. Stations

bridge the intercom line at a very high impedance

(more than 10K Ohms), and place a minimum load

on the line. High bridging impedance — plus

special load sensing circuitry — ensures that the

audio level always remains constant, and does not

fluctuate as stations are added or removed from

the system, as may occur on other professional

intercom systems.

Audiocom products provide users with valuable

features such as Remote Mic OFF, backlit lettered

buttons for darkened environments and

compatibility with every major intercom system on

the planet. In addition to the excellent Telex quality

and performance, Audiocom products provide users

with cost effective system pricing and world-class

technical support from one of the most experienced

sales, engineering and customer service teams in

the intercommunication industry.

Instantaneous Auto Reset™

The Audiocom Instantaneous Auto Reset™ (IAR) technology

is the next quantum leap in intercom performance and

safety. Revolutionary new circuitry dynamically monitors

line fault conditions and automatically and

instantaneously brings individual power supply channels

up when a fault condition is removed. This technology is a

far cry from the “if it gets too hot shut it down” systems

currently in use by other manufacturers.

Other systems may get extremely hot under short circuit

fault conditions and take 30 or more seconds to reset —

after a fault is removed an eternity when you are waiting

to give a critical cue. To make matters worse, in many

cases power provided from the affected multi-channel

supply feeding non-shorted intercom channels can also be

removed, taking down critical communications links that

should have otherwise been completely unaffected. In

addition to the power supplies potentially melting down,

this situation can create fire hazards.

In an effort to find a more elegant solution to the power

supply reset problem, Telex engineers took a new and

unique approach. The new Auto-reset technology utilizes

the same failsafe current-sensing circuitry currently found

in existing Audiocom systems to ensure the utmost in

safety and reliability, but, with IAR™, adds an intelligent

circuit to dynamically monitor the line and

instantaneously reset power upon fault removal.

IAR™ intelligent circuitry does not just wait for the unit

to cool off and turn the power back on to see if it draws

excessive current (as with other manufacturers); it

actively and continuously evaluates the line condition.

Using advanced comparator circuits, it instantaneously

restores power to the affected intercom channel as soon

as it is safe to do so. The whole process of restoring

power after the fault condition is removed takes less than

500 milliseconds. That’s 60 times faster than the

competition!

By using readily available off the shelf components to

create this innovative new Auto-reset technology Telex

engineers have raised the bar of power supply

performance and safety to a whole new level. All future

Audiocom power supplies will be fitted with this new

technology. Users and facility managers can rest assured

that, regardless of conditions down line from the power

supply, Audiocom’s Instantaneous Auto Reset technology

will ensure a safe and immediate return of intercom

power when the fault is removed.

...Just a few of the ways Telex Audiocom engineers are

providing innovative solutions for today’s

communications.™
