Notices and Cautions
CAUTION:
The installation and service instructions in this manual are for use by qualied personnel only. To avoid electric shock,
do not perform any servicing other than that contained in the operating instructions unless you are qualied to do so.
Refer all servicing to qualied personnel.
This instrument has an autoranging line voltage input. Ensure the power voltage is within the specied range of 100-
240v. The ~ symbol, if used, indicates an alternating current supply.
This symbol, wherever it appears, alerts you to the presence of uninsulated, dangerous voltage
inside the enclosure – voltage which may be sufcient to constitute a risk of shock.
This symbol, wherever it appears, alerts you to important operating and maintenance instructions.
Read the manual.
CAUTION: DOUBLE POLE/NEUTRAL FUSING
The instrument power supply incorporates an internal fuse. Hazardous voltages may still be present on some of the
primary parts even when the fuse has blown. If fuse replacement is required, replace fuse only with same type and
value for continued protection against re.
WARNING:
The product’s power cord is the primary disconnect device. The socket outlet should be located near the device
and easily accessible. The unit should not be located such that access to the power cord is impaired. If the unit is
incorporated into an equipment rack, an easily accessible safety disconnect device should be included in the rack
design.
To reduce the risk of electrical shock, do not expose this product to rain or moisture. This unit is for indoor use only.
This equipment requires the free ow of air for adequate cooling. Do not block the ventilation openings in the top
and sides of the unit. Failure to allow proper ventilation could damage the unit or create a re hazard. Do not place
the units on a carpet, bedding, or other materials that could interfere with any panel ventilation openings.
If the equipment is used in a manner not specied by the manufacturer, the protection provided by the equipment
may be impaired.

A Note From Frank Foti • viii

War of the Waves
Dear Valued Customer,
It’s with great pride and a tip of the hat to an incredible team that I congratulate you on your new Telos Alliance
product. Everything we do here at the radio division of the Telos Alliance is with one end goal in mind: To help
broadcasters declare victory in extremely competitive environments. By purchasing this product from us, in essence,
you have declared war on your competition.
After all, the majority of Telos Alliance employees were broadcasters themselves once, and the products we’ve
developed over the years have been designed as solutions to specic issues faced on the front lines of our industry.
We’re right there in the trenches with you and have the weapons you need in your arsenal.
Telos Systems is a catalyst to out-of-this-world sound, with the most powerful and popular broadcast telephone
systems in the industry; IP/ISDN codecs and transceivers; plus processing/encoding for streaming audio. We built an
industry on the back of these amazing telephony systems, and they are still going strong.
While we at the Telos Alliance never forget our roots, we are also blazing trails in terms of new technologies like
stream-encoding and AoIP, so that all types of broadcasters can excel in this ever-evolving digital world.
Omnia Audio not only lets you stand out on the dial with your unique signature sound via legendary audio
processors, audio codecs, and microphone processing, it lets you give your listeners a better streaming experience
across devices with innovative stream encoding/processing software and hardware.
Axia Audio is a driving force behind the AES67 AoIP standard, and its networked AoIP radio consoles, audio
interfaces, networked intercom, and software products continue to move AoIP adoption forward and help
broadcasters streamline operations with cohesive, smart, and feature-rich AoIP ecosystems.
Last, but certainly not least, 25-Seven has traditionally been known for its audio delays, but its Voltair watermark
monitor/processor has made a name for itself more recently as the disruptive product that helped broadcasters take
back their ratings and harness the true power of their listening audiences.
You work so hard on your programming day-in and day-out, it deserves technology that will optimize sound and
performance at every point in the airchain and online. Armed with Telos products, you have what you need to set
your competition squarely in your crosshairs.
With that, I’ll leave you to prep your armaments. I hope that you will enjoy your Telos Alliance products for many
years to come!
Sincerely,
Frank Foti
CEO, The Telos Alliance

The xNode family:
• Analog Input/Output xNode: 4 Stereo Analog Line-level Inputs, 4 Stereo Analog Line-level Outputs
• AES/EBU Input/Output xNode: 4 Stereo Digital AES-3 Inputs, 4 Stereo Digital AES-3 Outputs
• Microphone Input/Output xNode: 4 Mic Inputs, 4 Stereo Analog Line-level Outputs
• GPIO Logic xNode: 6 GPIO Ports, each with 5 Opto Inputs and 5 Opto Outputs
• Mixed Signal Input/Output xNode: 1 Mic/Line Analog Input, 2 Analog Line Inputs, 1 AES-3 Input, 3 Ana-
log Line Outputs, 1 AES-3 Output, 2 GPIO Ports, each with 5 inputs and 5 outputs.
• Each of the xNodes support IEEE 802.3af power over Ethernet (PoE) .
• xNodes have a front panel OLED display for setup and status.
• The rear panel contains the audio input/output connectors, the Ethernet connectors and an IEC AC input-
connector.
• The xNodes are in small form factor, 1U Half-Rack.
• Two mounting kits are available as options; Surface-mount or Rack-mount.
• Dual 100BT Ethernet ports, usable as mirroring redundant ports or as a single Livewire port and separate
management port.
• Thermal sensor monitors temperature and provides notication of over-temp condition.
