INTRODUCTION | 1

1 Introduction

Congratulations on your purchase of the Telos Z/IP ONE! This codec achieves a new level in IP Audio transmission
at a very attractive price. It is a one RU unit intended to be used with a microphone directly, or an external mixer for
remote broadcasts, or anywhere space is at a premium.

The Telos Z/IP ONE combines RTP/UDP streaming capabilities with MPEG coding to deliver broadcast-quality
audio over IP connections. Z/IP ONE employs sophisticated new technology to achieve superb audio quality over
IP networks such as the Internet and mobile IP services. The Z/IP ONE utilizes ACT™ - Agile Connection Technology
to continually adapt to network conditions, minimizing the effects of packet loss, varying bandwidth, and jitter
that can occur on these networks by means of sophisticated error detection and concealment, dynamic buffering,

and other techniques that work together to provide reliable IP audio connections.

The Z/IP ONE has an impressive list of features, including:

♦ Analog line professional or microphone input levels

♦ AES/EBU digital input and output

♦ 15 volt phantom power for direct use with condenser microphones

♦ Transmission bit rates from 8kbps to 2304 kbps

♦ User-friendly front panel interface with OLED screen

♦ Real-time metering and connection status display screen

♦ Context-sensitive on-screen help available at a touch of a button

♦ EBU N/ACIP (Audio Contribution over IP) and SIP interoperability with other third party codecs

♦ Backward compatible with the Telos Zephyr Xstream, as well as the original Zephyr/IP

♦ Built-in web server for configuration and remote control

♦ Wireless connection through Wi-Fi and 3G/4G/EVDO modems (Wi-Fi modem included)

♦ Livewire™ audio-over-IP inputs and outputs

♦ Separate LAN and WAN Ethernet ports simplify isolation of your LAN from the internet

♦ The ability to register with a “directory server” (ZIP Server). This allows establishing a connection

even when located behind NATs and firewalls, without knowing the other party’s IP address

♦ Router Mode allows the Z/IP ONE to be used as a gateway to access the Web

QUICK START GUIDE | 3

2 Quick Start Guide

This quick start will guide you through a basic, yet perfectly usable setup scenario of the Telos Z/IP ONE IP audio codec.
More sophisticated configurations are available, and are preferred or even necessary in some IP network situations.

2.1 Unpack and Identify

Your Z/IP ONE is shipped with a few accessories that we won’t use for this initial setup, but you may want to use
later. For now, we’ll want the Z/IP ONE itself, AC power cord, and a network cable – all included with the Z/IP ONE.

To test the Z/IP ONE, you’ll also need:

1. Headphones – or connect the Z/IP ONE’s audio output to an audio monitor.

2. Microphone or audio source (optional)

3. An Internet-connected Local Area Network with DHCP Server (You may set your Z/IP ONE’s network

configuration manually if you prefer)

The basic steps to follow are:

1. Attach AC power cable and power up

2. Follow the built-in Setup Wizard

3. Connect to the Internet

4. Make your first call

4 | Section 2

2.2 The Z/IP ONE User Interface

The Z/IP ONE uses an OLED display for status, metering, and configuration. There are six menus available:

Turning the Z/IP ONE’s control knob will move the highlight between these options. The name shown in the middle
of this screen is the device’s identity on the ZIP Server, used for making calls without having to memorize IP addresses.

Z/IP ONEs with software earlier than v2.0.0r, such as the one shown above, had the version number printed on the
main screen instead. If your Z/IP ONE is not running at least v2.0.0r, please update your codec to the latest released
version of software. The latest version is always listed and available for download here:

http://www.telosalliance.com/codecs/zip-one/

If the front panel controls are not used for a short period of time, the display will revert back to a status screen
(by default, the last status screen viewed):

2.3 Setup Wizard

One option for initial setup of the Z/IP ONE is using the built-in Setup Wizard. The Setup Wizard will work in
most common IP networks, and requires little technical knowledge. Let’s walk through it:

From the Main menu, highlight and select Setup. From the Setup menu, highlight and select Setup Wizard.

Click to Continue. Select the WAN Ethernet connection.

QUICK START GUIDE | 5

Select the Analog XLR connectors for audio input. Answer “Yes” to allow control of your unit from either port.

Let’s answer “No” to the SIP server question.

Answer “Yes” here. We’ll use this port.

Then click to Apply settings and exit Click OK to complete the Setup Wizard.

Plug your Internet-connected network to the WAN port.

Keep this easy; answer “Yes” here.

Using the keypad, enter a name for this Z/IP ONE.

Then, highlight and select Status.

The top Status screen should show WAN connected. Within a few seconds, the ZIP light should come on, too.

The ZIP indicator is your assurance that your Z/IP ONE is communicating with the Telos ZIP Server, and that
connections to other Z/IP ONEs and Zephyr/IPs are just two button presses away.

What if the ZIP indicator doesn’t light up? This condition is usually caused by a very restrictive network firewall,
a non-standard DNS configuration, or not having DHCP available to obtain an IP address automatically. Appendix
A offers information and suggestions about working through restrictive network firewalls and alternatively
configuring DNS.

6 | Section 2

2.4 Make Your First IP-Codec Call

Now that the WAN and ZIP indicators are ON, you’re ready to make your first Z/IP ONE IP call. Press the AUTO
button - it’s in the upper right corner of the keypad area. This brings up the phone book – a quick-dial list of the
other Z/IP ONEs you’d like to connect with.

Your Z/IP ONE is factory programmed with two contacts - the Telos Line in Cleveland, Ohio, USA, and the Euro
Line in Freising, Germany. Highlight “Telos Line” and press the AUTO button again (or push the main control
knob) to establish a call. As the call progresses and connects, the screen changes automatically to the main Status
display.

The large Connect indicator should come ON quickly, followed a few seconds later by the RcvLock indicator. The
Rcv audio level meters will begin showing moving audio levels. In a few more seconds the Buffer and Quality gauges
in the lower third of the screen will show relative indications of receive buffer size at both ends and quality of the
connection, indicating dropped packets.

Plug your favorite headphones into the front panel headphone jack. Adjust the volume knob that’s next to the jack
for a comfortable level. You’ll hear whatever music our Support Engineers have selected. Don’t be alarmed when
the Z/IP ONE automatically disconnects from the Telos test line. It will time out and hang up after 10 minutes. This
is to allow others to test Z/IP ONE connections, too.

QUICK START GUIDE | 7

2.5 Congratulations!

You’ve configured your Z/IP ONE and made your first IP-codec call. There are dozens of configuration options
within the Z/IP ONE, allowing it to work ideally in different broadcast and remote-audio roles. Consult the
manual, our online video tutorials, or Telos Support to get the most out of your Z/IP ONEs.

Info for IT experts:

You may choose to congure either the WAN or LAN port for streaming connections. We recommend
using the WAN port, saving the LAN (also Livewire) port for Livewire AoIP network connections.

Z/IP ONE connection success is virtually guaranteed by assigning it an unused static IP address on
your network, assigning a xed “ZIP Server Listen Port” in the ZIP Server menu, and conguring a
port forward from the Internet side of your rewall/router to the static IP address of your Z/IP ONE,
using that same “Listen Port” number. We suggest you choose a listen port in the 20000-21000 range
to avoid port conicts. Left unassigned, as in this Quick Start, the Z/IP ONE negotiates a listening port
with the ZIP Server. The ZIP Server is always located at zip.telos-systems.com, which is the factory
default setting. Incoming calls to the Z/IP ONE will connect instantly if a xed listen port is chosen
and a port forward made. Otherwise, each inbound call negotiation will take ve to ten seconds.

Placing the Z/IP ONE on a DMZ or un-NATted Public IP address is not recommended. A good choice
for a manually-congured DNS address is 8.8.8.8.

…Now what?

Most hardware codecs, such as the Telos Z/IP ONE, Z/IPStream, and iPort, offer a choice of audio coding
algorithms. With unhelpful names like “G.722”, “AAC-LD”, and “Layer 2”, how does one choose the best coding
algorithm for a given connection or use? A full discussion of audio coding is in Appendix B, Audio Coding Reference,
but the following tables summarize their features at a glance.

Live broadcasts of voice or music. Can use for
music if necessary. Quick interaction with studio
hosts and callers.

Music at lower bitrates. Best for one-way broad­casts where tight interaction with studio hosts
or callers is not critical. Works at very low bitrates
with some compromise in quality.

Music or voice at medium bitrates. When medi-
um bandwidth is available and interaction with
studio hosts or callers is needed, this is a great
choice.

Music at medium bitrates. For the medium range
of bitrates, this is the best codec to choose when
a little delay is okay. Quality is fully “awesome,”
especially at 256 kbps and higher.

Music or voice at medium bitrates to other
brands of codecs. Layer 2 is a great choice, espe-

cially for compatibility across dierent brands of
codecs.

Voice at low bitrate to other brands of codecs.
Not “high quality,” but much better than a stan­dard telephone call. It’s the most compatible low
bitrate codec with any other brand.

This is a “phone call.” Often used for compati­bility for SIP (VoIP) calls to or from regular tele­phones.

aptX® Enhanced is primarily used in professional
broadcast applications where low delay is desired
and cascading coding algorithms may be en­countered.

Perfect audio for perfect connections. If you’ve
got the bandwidth and a perfect IP path (low
jitter and no packet loss), this is the perfect “algo­rithm.” Bit rate is not variable, but is xed for given
mono/stereo and bit depth parameters.

INSTALLATION | 11

3 Installation

3.1 Rack Mounting the Studio Unit

The Z/IP ONE mounts in a 1RU space in a standard 19” rack. The Z/IP ONE does not have an internal fan, and does
not have any special requirements for space above and below the unit. As long as you keep the stirred air in the rack
between 0 and 40 Celsius (32 to 104 degrees Fahrenheit) with a relative humidity of 0 to 98% (non-condensing),
the unit will operate as described.

3.2 Power

Install the power cord included with the Z/IP ONE in the marked AC power connector located in the rear of the
unit. The internal universal switching supply will accept 100-240 VAC (50-60 Hz) input. You should see the blue
front panel LED flash to indicate the unit is booting. Subsequently, the main menu will appear. This process can
take about 90 seconds.

Install the left and right analog audio cables in the female XLR connectors marked “CH 1 In” and “CH 2 In” on the
rear panel. The analog audio section accepts audio input with a peak level of +22dBu. In the Audio I/O -> Input
mode Left or Right menu option, each audio input can be configured for the following settings:

♦ Line (+4 dBu nominal)

♦ Microphone

♦ Mic + Phantom Power

Mic Gain Trim

There is a microphone gain trim adjustment option in the Setup->Audio I/O menu for each input, which can be
used to add additional gain when that input is set to microphone level. This setting is ignored when an input is set
to line level. Gain should be adjusted so that the microphone reaches your desired level on peaks.

You can select between 48 kHz, 44.1 kHz, 32 kHz, and Sync to AES-Input. All of the fixed sample rate settings are
relative to the Z/IP ONE’s internal sample clock. Use Sync to AES-Input if the device connected to the Z/IPONE’s
AES outputs does not have its own sample rate converter, or to sync to a facility-wide clock. Regardless of the
sample rate chosen, the encoded audio streams will always use 48kHz sample rate.

3.7 Network Interfaces

The Z/IP ONE is designed to work on managed private networks or the public Internet. For reliable operation
when connected to the public network, the Z/IP ONE must be placed behind a firewall. These are commonly
included in network address translating routers, commonly called either “NAT routers” or simply “routers.”
The Z/IP ONE conjunction with the ZIP server on the public Internet, has technology for automatically creating
connections without requiring port forwarding on most styles of NAT routers. For more information on these
topics, see Chapter 9, Audio Streams and Appendix A, When an IT Department is not Available.

The network interfaces are Ethernet, twisted pair, 100BaseT connectors. Use a CAT5e or CAT6 network cable. The
standard pin-out for an RJ45 style 8-Pin/8-Position miniature modular jack when used for 10/100BaseT Ethernet is:

PIN FUNCTION
1 Transmit +
2 Transmit ­3 Receive +
4 Unused
5 Unused
6 Receive ­7 Unused
8 Unused

3.8 USB Ports

Attach any of the supported USB devices to these ports. Use of an unapproved device may cause unpredictable and
unacceptable results. Therefore, we recommend against such experimentation. The pin-out of the standard USB
connector used in the Z/IP ONE is:

4.1 Front Panel Controls

Headphone Control Knob

This is a volume control and monitor selection button. Turning the knob will change the headphone volume. Pushing this
button will select between the receive audio and the transmit audio. Neither of these function will affect the audio on the
main outputs. While changing the volume, the display will indicate which audio is present on the headphones.

Main Control Knob

Rotating the Z/IP ONE’s control knob moves the cursor. It also has a push-to-click function. Pressing the knob selects the
highlighted menu selection, or accepts the current value the setting that is being edited.

ESC Button

This button escapes from the currently selected menu or dialog screen. While editing a setting, pressing the ESC button
cancels any edits and leaves the field unchanged. From the main menu screen, pressing ESC will take you to the status
screens (and vice versa).

The Number Pad

The dial pad is used to enter data in edit fields. If the field accepts only numeric data (or IP addresses), then
pressing the buttons will enter the number pressed.

Other fields accept alphanumeric strings. In these fields, the buttons cycle through the number, then the alphabetic
characters in uppercase, and then in lowercase. The 1, 0, *, and # buttons allow you to enter special characters and
punctuation.

The Connection Buttons

On the right side of the front panel, the Z/IP ONE has three buttons (labeled AUTO, CONN, and DISC) for setting
up and dismissing connections. The function of each of these keys is as follows:

♦ AUTO gives you quick access to your “phone book.” This screen displays the current status of other Z/IPs,

so that you can see if they are available before you call. Pressing AUTO or the control knob while in the
phone book will immediately dial the selected entry

♦ CONN takes you to a manual dialing screen on which you can enter the details of the codec you wish to call

♦ DISC is used to terminate connections. You will be prompted to confirm the disconnection. Pressing

DISC again while on this screen or selecting the Yes button with the main control knob will end the call

4.2 The User Interface and Menu System

After a period of inactivity, the Z/IP ONE will time out to a status screen. Pressing the ESC button will return to
the menu system. Rotating the main control knob moves from option to option, while pressing it will select the
currently highlighted item. While in a menu, pressing ESC will back you up one level. Repeated presses will take
you to the main menu.

From the main menu, you can access the Status, Phonebook, Audio I/O, Setup, Help, and call History sub-menus.

Getting Help!

Context-sensitive help is available at any time by pressing the 1 button. General help can also be accessed by
choosing Help from the main menu.

Clearing Alerts

When a condition exists that requires attention, the Z/IP ONE will display an alert box in front of whatever screen
is otherwise active. To close the current alert, press the ESC key. To close all alerts in the stack, press the 0 key. All
alerts will also be closed automatically if a successful connection is made (either incoming or outgoing).

The Z/IP ONE keeps a list of all alert screens that have been displayed since the last time it was rebooted.
This list is shown on the Logs web page.

THE AUDIO I/O MENU | 19

5 The Audio I/O Menu

This menu gives access to the various settings related to audio into and out of the device.

5.1 Audio Input Source

The Audio Input Source item chooses which audio input is encoded and transmitted to a remote codec. You must choose
between the Analog XLR, AES/EBU XLR, and Livewire for the input (transmit) audio.

If you decide to use the Livewire input, you will also need to choose a Livewire input stream in the Setup>Network>Livewire
menu. Like the XLR outputs, the Livewire output is always active, provided that a Livewire source number is configured on
the Livewire setup page. To disable Livewire outputs, set the Z/IP ONE’s source number to 0.

In addition to selecting the audio source to transmit, this menu allows you to configure your Z/IP ONE for redundant
audio inputs, to help protect against failures. To use this feature, select either the AES/EBU + failover or Livewire + failover
option.

When using Livewire + failover, the Z/IP ONE will prefer Livewire audio if it is available. If it is not, for whatever reason,
the Z/IP ONE will use the AES/EBU input for its transmit audio. If the AES/EBU stream is unavailable, it will use the
Analog inputs. The Z/IP ONE will also revert back to a more preferred audio source when the problem is cleared and the
preferred stream has been stable for some time.

When using the AES/EBU + failover option, the Z/IP ONE’s behavior is as above, except it will never use Livewire for the
audio input.

20 | Section 5

5.2 Input Mode

The Input Mode Left and Input Mode Right menus select the behavior of the Analog XLR inputs. You can choose
between Line-level inputs, Microphone-level inputs, or mic-level inputs with 15V phantom power enabled. The
exact gain of the input is dependent on the mode, and selected by items further down this menu.

5.3 Microphone-level Gain

Use the Mic Gain Trim setting to set the gain level of the analog XLR inputs. This only affects the inputs that are set
to Microphone, but if both the left and the right inputs are microphones, they must both use the same gain level. The
available microphone gain is from +23.5dB to +47.5dB in 1.5dB steps.

5.4 Line-level Gain

The Line Gain Trim L and Line Gain Trim R items set the gain of the respective analog XLR inputs. These settings
only affect inputs that are set to Line. The left and right Line-level gains can be set independently, from -12dB to
+12dB, in 1.5dB steps.

5.5 Transmit Mode

The Z/IP ONE can be configured to transmit stereo audio, or sum inputs to send a mono stream. The Transmit
Mode setting affects all input types.

Some codecs only support stereo or mono operation. When using these codecs, the proper transmit mode is used
automatically, so the transmit mode setting will never affect codec availability when configuring a call. However,
be aware that in many codecs, changing the stereo mode does change the available range of bit rates. After changing
the stereo mode, the codec setup page will automatically show the new bit rat range available for the selected codec.

For an ‘at a glance’ display of all codecs and how they are affected by the transmit mode, see the Audio configura­tion webpage.

5.6 AES/EBU Output Sample Rate

Use the AES/EBU Output setting to select the sample rate of the AES/EBU audio output by the Z/IP ONE. You can
select between 48 kHz, 44.1 kHz, 32 kHz, and Sync to AES-Input. All of the fixed sample rate settings are relative to the
Z/IP ONE’s internal sample clock. Use Sync to AES-Input if the device connected to the Z/IPONE’s AES outputs
does not have its own sample rate converter, or to sync to a facility-wide clock. Regardless of the sample rate
chosen, the encoded audio streams will always use 48kHz sample rate.

5.7 Loopback

The Audio Loopback setting is intended for local audio testing. When set to PCM Direct, the configured input will
appear on all local outputs (analog XLR, AES/EBU XLR, headphone, and Livewire (if configured)) without any
compression. When set to Encoded, the configured audio input will appear on all outputs after it has been encoded
and decoded. When in loopback, the Z/IP ONE uses the maximum bitrate configured for the codec.

To stop looping audio, change the setting to Off. The Z/IP ONE will also automatically end the loop mode if the
codec is rebooted or powered off.
