Optimum Flexibility and Performance

For Highly-Dynamic Production Communications

HelixNet Partyline Platform

The Clear-Com HelixNet platform is the latest stage in intercom
evolution. Based on the groundbreaking I.V. Core Technology,
HelixNet delivers the legendary “Clear-Com Sound” you’ve come
to expect, along with the added benets of network intelligence,
ease of operations and simplied cabling.

Cabling Simplicity

Employ exible cable
options with the ability
to leverage an existing
cable infrastructure.

station with a single cable.

ABOUT I.V. CORE TECHNOLOGY

Clear-Com’s Instant Voice Core (I.V. Core) is a suite of Internet Protocol (IP)
technologies at the heart of all HelixNet products. I.V. Core delivers:

• Low latency through the use of an intelligent decision engine that routes

• Superb audio quality through the use of wideband CODECS, enabled thanks

• Encryption, noise-reduction, and error-recovery through proprietary algorithms

Traditional Voice-Over-IP solutions mix and encode audio at the server, consuming
valuable IT network resources, reducing audio quality, and adding latency. In contrast,
the I.V. Core routes only packets that contain actual voice data, mixing and encoding
them just once at the client, thereby delivering a higher quality voice communications
experience than ever before possible.

only the audio packets containing needed voice information.

to a highly optimized design that eliminates multiple encode/decode cycles.

optimized for human voice characteristics.

MAIN STATION

The HMS-4X HelixNet Main Station provides power and up to 20
networked channels of audio to support up to 20 digital beltpacks. The
sleek 1RU digital system can be mounted into any standard 19" rack.

MAIN STATION HIGHLIGHTS

High Channel Density. Up to 20 networked intercom

channels and power for beltpacks transmitted over
a single shielded twisted-pair (Ex. microphone cable,
CAT5, or CAT6 cable).

No Rewiring Required. System designed to preserve
investment by operating on existing infrastructure.

Single Cable Operation. Fewer cables save time
and cost during setup and conguration.

No Hum. No Buzz. All-digital system offers immunity
to electro-magnetic interference and ground loops.

High User Capacity. A single HMS-4X Main Station,
offering four channels, can support up to 20 beltpacks.
Main Stations can be connected over LAN or ber to
support many beltpacks over a network.

Quick Startup. Get up-and-running fast and effortlessly
with easy plug-and-go installation and hardware
auto-discovery.

Seamless Linking. Main Stations share resources over
a LAN or Fiber link so users can select local or remote
partyline channels and program audio feeds from the
beltpack. Optional two-wire and four-wire interface
modules further extend connectivity to existing analog
partyline or matrix intercoms.

Easy-to-Navigate Menu. Quick access to system settings
and conguration for fast and painless set up.

BELTPACK

Delivering superb digital sound quality, the two-channel HBP-2X HelixNet
Beltpack enables access to two of any four system channels over a
single cable. The rugged, ergonomically designed HelixNet Beltpack
was created to perform on the big stage, offering reliability and durability
that will withstand the most demanding production environments.

BELTPACK HIGHLIGHTS

Channel Density. Similar to a source assignment panel,

a single cable gives every connected beltpack the
capacity to access all networked system channels.

Selectable Channels. The full-duplex, two-channel
beltpack can select up to two of the available system
channels and program audio feeds, each with individual
level control.

Save Resources. Networked audio is distributed over
a single shielded twisted pair, reducing the number
of cables to yield time and cost savings.

Passively Interconnection. Beltpacks can be set
up in daisy-chain or star congurations with no need
for active split boxes.

Clear-Com Sound: Legendary contoured audio
frequency response provides maximum intelligibility
and exceptional sound quality.

Efficient Administration. System conguration
and rmware upgrades are centrally managed
from the main station.

Intuitive Operations. Present logical channel labels
on the high-contrast, 10-character OLED display.

Effortless Navigation. Optimally positioned buttons
and volume knobs are easy to locate, identify and
control on the beltpack.

LINKING MODULES

HelixNet Main Stations accept Ethernet and Fiber as well as two-wire
and four-wire optional interface modules, offering seamless linking
over LAN or Fiber and connection to virtually all common two-wire
and four-wire audio systems.

HLI-ET2 ETHERNET MODULE

The HLI-ET2 Ethernet Linking Module provides a dual
LAN interface to connect to other HelixNet Main Stations.
Once connected, stations share partyline channels and
program audio, and make them available to any station
and beltpack on the linked system. All labels are trans­ferred across the network automatically.
