A LETTER FROM OUR VICE PRESIDENT | vii

The most compelling audio content and programming

originates with the human voice. Pundits, perpetrators,

experts, celebrities, newsmakers, victims, moderators,

and listeners - they all have opinions. Many want to be

heard. And listeners want to hear them.

It’s for this reason that voice quality over the challeng-

ing and changing Public Switched Telephone Network

is an engineering passion for us. Telos’founder, the late

Steve Church, introduced Digital Signal Processing to

broadcasters for the rst time with the revolutionary

Telos 10 phone hybrid. Since that invention, Steve and

our engineering/development teams have brought

multi-line talkshow systems, ISDN capabilities, and

even large-scale T1- and PRI-based talkshow systems

for multiple studios.

Now that Voice Over IP is becoming commonplace,

broadcasters benet again from a Telos innovation -

the Telos VX talkshow system. VX connects directly to

VoIP over SIP connections and uses Livewire AoIP to

bring those clear caller voices right into your audio

console or production workow. VX’s IP connectivity is

allowing broadcasters to upgrade to“HD Voice”quality

for on-the-spot reports and priority listener calls.

IP connections are quickly becoming the go-to stan-

dard for broadcast remotes, studio-transmitter links,

and audio content distribution. Whether for main or

backup service, permanent or short-term use, Telos

codecs are built for professional use and jaw-dropping

audio quality. The Telos Z/IP ONE is designed to work

well over the Public Internet, and includes Agile Con-

nection Technology, enabling fast responsiveness to

changing and challenging bandwidth conditions. The

Z/IP ONE is perfect for remote talent, with low-latency

and simplied, two-button connections. Z/IP ONE also

aords super-reliable operation for STL and other pro-

gram links; and works over any IP link: IP radios, ber,

Internet, or private WAN.

On the pages that follow, you’ll see tools, equipment,

and systems designed to connect your listeners with

compelling audio content. They’ll connect your talent

with listeners, experts, and events with hardly a second

thought to the amazing technology inside.

Thank you for your own dedication, ideas, and com-

ments. Please tell me how you’re creating compelling

content with Telos, and how we can help you do that

even better!

My best,

Kirk Harnack

Vice President and Executive Director

1Introduction

1.1 The Hx6

Congratulations on your purchase of Hx6, the latest in multi-line talkshow systems from

Telos. Hx6 combines a six line selector and two third-generation Telos hybrids with Digital

Dynamic EQ. Hx6 also comes with the new AEC – Advanced Echo Cancellation – from

Fraunhofer Labs, revolutionary technology that eliminates open-mic feedback. The two

hybrids are designed to be used within a single studio for airing simultaneous callers and

achieving optimal audio quality.

Hx6 may be controlled by an attached Telos VSet6 phoneset, or by a producer’s PC with

the included Broadcast Bionics Xscreen Lite call screening software. A network interface

connector (RJ45 Jack) is located on the back plane for direct connection to a controller or a

suitable network switch for support of multiple controllers.

The Hx6 may be ordered with either POTS or ISDN (Integrated Service Digital Network)

interface. This provides support for the connection of six lines for the two integrated hybrids.

Audio input and output is accomplished through XLR connectors on the back panel.

♦Two XLR-Male connectors for audio from Hybrid-1 and Hybrid-2.

♦Three XLR-Female connectors for audio input to Hybrid-1, to Hybrid-2, and for POH

(Program on Hold).

The Hx6 also supports Livewire audio for connection to a Livewire audio routing system

through the network interface.

The Hx6 has two female D-subminiature 9 pin connectors for GPIO (General Purpose

Input Output).

1.2 Features

Back in the 1980s, Telos pioneered the application of Digital Signal Processing to broadcast

telephone hybrids - a huge step forward from the hot-rodded AT&T speakerphones that

stations had been using. In the decades since, we’ve signiﬁcantly advanced the art of broadcast

telephony. Your Hx6 system represents the highest state of that art. It includes:

♦The most advanced digital hybrids yet devised for POTS and ISDN phone lines.New

symmetrical wide-range AGC and noise gate by Omnia, with adjustable gain settings.

♦Studio adaptation and pitch shifter to prevent feedback in situations where open

speakers are required.

2| Section 1

♦An adjustable caller override that improves performance and allows you to individualize

the degree to which the announcer ducks the caller audio.

♦Telos-exclusive Digital Dynamic EQ (DDEQ) to keep audio spectrally consistent from

call to call.

♦Separate Send level and Receive level meters for each hybrid.

♦Worldwide disconnect signal detection (loop drop, dial tone, or reorder tone).

♦A Livewire Ethernet AoIP interface for one-click connection to Axia studio networks.

♦Conference linking for high-quality conferencing between callers with no external

equipment needed.

♦Caller ID support on both ISDN and POTS lines.

♦Support for up to twelve controllers.

♦VX control protocol for compatibility with Telos VSet phones and call screening

software which supports the VX protocol.

1.3 Integrated Service Digital Networks (ISDN)

The Hx6 works with either traditional analog Telco lines or with ISDN (Integrated Services

Digital Network). We recommend ISDN service for telephone connections whenever possible.

There is no comparable technology for getting audio to and from the public telephone network.

Even compared to VoIP, ISDN is superior, with its lower delay and higher quality of service.

We provide plenty of advice right here in this manual and live support by people with years of

ISDN experience. (Thousands of Telos ISDN interfaces and Zephyrs are deployed around the

world!) Currently, the dial-up telephone network is nearly entirely digital. Only the “last mile”

copper connections from the telephone Central Oﬃce exchange to the customer’s site remain

with the archaic analog scheme. ISDN oﬀers us a way to link the studio directly into the Telco

digital infrastructure without the usual impairments of analog connections.

While the application of digital signal processing to the problem of separating announcer

and caller audio – pioneered by Telos and used in all of our telephone interfaces – has made

a dramatic improvement over analog-only hybrids, using digital phone lines for on-air calls

further improves performance for several reasons:

1. Exceptional send-to-receive isolation. Traditional analog phone lines multiplex both

speech directions in order to use a single pair of wires for a conversation. This causes

what’s referred to as ‘leakage’ – when the announcer’s audio is present on the hybrid

output, creating an annoying ‘hollow’ or ‘tinny’ sound. Telos digital adaptive hybrids

reduce this problem. But ISDN oﬀers independent and separated signal paths, so our

hybrids only have to operate on the far-end analog line, if any. The result is much lower

leakage.

2. Higher send levels. We don’t have to be concerned about regulations designed to prevent

crosstalk on analog lines, so we can increase send-to-caller levels.

3. Lower distortion. The analog-digital conversion chips used in telephone central oﬃces

are poor compared to the converters used in professional audio equipment. Fidelity

is not an important consideration when telephone equipment designers choose parts

for this function. In a professional interface for studio applications, we can aﬀord to

design-in much better converters. Noise-shaping functions permit a larger word-length

converter to provide signiﬁcantly better distortion and signal-to-noise performance.
