Company to Display Groundbreaking HelixNet™ Intercom Platform and Enhancements to Tempest®2400 Digital Wireless

LONDON, UK, 12, SEPTEMBER, 2010 ─ Clear-Com®, a global leader in mission-critical voice communication systems, will bring its innovative unified intercom platform, HelixNet™, to the entertainment and installation industry at this year’s PLASA 2010 (Stand 1.J35). In addition, the company will showcase its enhanced version of Tempest®2400 digital wireless intercom system, which is now shipping worldwide.

In today’s world of live production, crew members coordinating live events such as sports, breaking news, political conventions and other scenarios, require rugged, reliable wireless operation and are challenged with making more happen with less time, more complex technology and fewer resources. Recognising that communication still plays a critical role in enabling a well-coordinated production workflow, Clear-Com’s latest intercom innovations are much simpler to set-up, use and manage, while still

offering the level of sophistication, flexibility and scalabilities that live production demands. HelixNet and Tempest2400 are solutions that meet these challenges.

HelixNet Unified Intercom Platform Sets New Communication Standard
HelixNet, a digital intercom platform based on Clear-Com’s award-winning I.V.Core Technology, offers the best mix of technical capabilities for live productions. HelixNet products share a common design philosophy ─ cabling simplicity, ease-of-use, networking flexibility, system intelligence and audio clarity. On display for PLASA attendees will be the first two products in the family, the HelixNet Main Station (HMS-4X) and HelixNet Beltpacks (HBP-2X).

Supporting four channels and 20 beltpacks, HMS-4X offers the simplicity of group communication and the high-channel capacity and flexibility of point-to-point matrix systems. As do all HelixNet products, HMX-4X works on a wide variety of standard twisted-pair cabling, such as microphone cables and CAT-5, to simplify the setup process and reduce the overall cost for infrastructure. The Main Stations can operate over a facility’s pre-existing cabling and, in the near future, will connect via standard LAN / IT network infrastructure. Furthermore, power and all audio channels are transported over a single cable. HelixNet Main Stations have built-in expansion bays for 2-wire or 4-wire interface modules to connect with analog partyline, digital matrix or wireless intercom systems. USB connectivity provides easy and instant software and firmware maintenance and upgrades.

The 2-channel HelixNet Beltpack is the most rugged and ergonomic beltpack Clear-Com has designed to date. It features unique tactile controls for intuitive touch operation and bump-proof volume knobs, making navigation on this feature-rich 4-channel system easy to master. The Beltpack also features a high-contrast OLED status display for easy visual operation. Its sturdy, ergonomic design assures reliability and durability that will last through the most demanding conditions. Moreover, HelixNet beltpacks interconnect passively facilitating dynamic cabling options: Y-splits, one-to-many splits, daisy-chaining beltpack to beltpack along with a mix of wire guage are all possible.

Enhanced Tempest2400 Offers More Capacity, Flexibility and Features
Version 2.0 firmware update for Tempest2400 introduces many appealing new features and functions that increase the capacity, flexibility and usability of the system. In addition to the Normal Mode that offers up to five full-duplex BeltStations per BaseStation, Shared and Split Modes were added to allow for an unlimited number of users per BaseStation. In Shared Mode, all of the BeltStations can utilize the dual listen/talk feature and BeltStation users can individually select which channels they listen and talk to just like in normal mode. While all of the BeltStations can talk, only five BeltStations may have talk enabled at any one time. If a sixth BeltStation tries to talk, the user will receive a busy signal. In Split Mode, users operate in a combination of the other two modes: Normal and Shared, offering the use of four BeltStations that utilizes the standard anytime talk back capability and an unlimited number of BeltStations sharing one talk path at any given time.

Other new features also include BeltStation push and turn volume control, push and hold channel changing, a 4db gain increase on 4-wire I/O BaseStations and the ability to control remote BeltStation sidetone levels and mic gain from the BaseStation or the T-Desk software program.

Tempest2400, available in two- and four-channel versions, is a cost-effective option for live production professionals who require fewer channels of communications and offers users unprecedented access to license-free communications. Utilizing patented Frequency Hopping Spread Spectrum radio technology to ensure robust, reliable communications, Tempest2400 operates license-free in the 2.4 GHz band worldwide, allowing interference-free communications even in environments heavily populated by other wireless devices.
