Introduction
Introduction
In 1991, CoachComm pioneered a new era in sideline communications and CoachComm’s wired systems were quickly recognized
as the best in the industry. Since 1997, CoachComm, LLC has been offering wireless products to meet the communications needs
of the football coaching market beginning with the UC series system. Based on the Telex® BTR/TR 600 digital radios, the UC
system became the standard for sideline communications for Division 1A football as well as for most professional teams.
While very popular, the UC system was limited with regards to its ability to perform in certain RF environments. Each system has
two (2) unique operating frequency sets, therefore a team can either be on frequency set “A” or set “B”. With the proliferation of
digital television broadcast signals in recent years, UC systems have experienced more RF interference from outside sources.
In addition to RF considerations, coaches were demanding increased audio quality, more wireless users, and several other
operational enhancements. Considering all of these factors and operational issues, CoachComm created the new NG series
system.
The CoachComm NG series system is an advanced, multi layered communication system for football coach communications.
NG addressed features not included in its predecessor, UC, with features such as frequency agility, an increased number of
wireless users, substantially better audio quality and a host of other refinements.
Even though the NG series represented a huge improvement with issues surrounding user operation, complexity and continuing
problems within the frequency spectrum for Part 74 devices, CoachComm elected to develop a new sideline communications
system that was completely outside of the Part 74 FCC rules and that has enhanced user features and ease of use. The new
system is called Tempest NG. While the wireless portion of the Tempest NG system is new technology, the central infrastructure
of the Tempest NG system is identical to the previous NG system. Therefore, the nomenclature of “NG” was retained.
The wired portion of the Tempest NG Series system is designed around the Telex® AudioCom® platform. The AudioCom®
Platform is the only sports communications system that employs two very important audio concepts: the balanced line concept
and the transformer isolation concept.
The AudioCom® system uses a balanced line approach to signal transmission. This means that the system is more forgiving
on twisted pair and that it is not necessary to “balance” the dry pair as you have to do in unbalanced systems. This makes for
faster setup and easier configuration changes. The transformer isolation employed in AudioCom® BeltPacks is one of the most
important features of the wired system. This transformer, located in each BeltPack, isolates the user from potential sources of
noise in the dry pair. It may not isolate every noise, but it does remove the most annoying buzzes and crackles associated with
other systems.
Expandability and adaptability are keys to the Tempest NG system. Users can be put into and taken out of the system without
affecting other users. In other systems, taking a user out of the line may cause an increase in system volume or a change in
system impedance resulting in voice quality degradation. In the Tempest NG system, however, adding and removing users is
virtually transparent.
This is the most advanced intercom system in use today. We highly recommend that you thoroughly read and study this manual.
