DANTE®MICROPHONE/LINE INTERFACES
1 DESCRIPTION
The Iyo Dante® is a cost-effective family of microphone/line
Dante audio-over-IP (AoIP) interfaces in a 1U rack mount
format.
Several models provide various configurations of balanced
analog audio inputs and outputs. Each input accommodates
microphone through line level signals with a range of -60 to
+24dBu. +48V phantom power is individually switchable on
each input. Output levels are configurable up to +24dBu.
RGB LEDs on the Iyo’s front panel show per channel audio
levels and streaming status.
The Iyo family feature an embedded web server, allowing
configuration and monitoring of input and output levels.
Routing is achieved using the Dante Controller.
Power is provided from a built-in universal AC power supply.
Redundant power is available using an external 12VDC
supply via a locking 2.1mm jack.
All units can also be operated in AES67 interoperability mode.

10INTRODUCTION
About Dante10.1
Based on industry standards, Audinate created Dante, an uncompressed, multi-channel digital media networking
technology, with near-zero latency and synchronization. Dante is the preferred audio networking solution that has
been adopted by more pro-audio AV manufacturers than any other networking technology. Interoperability is not a
dream of the future, but a reality today. Hundreds of Dante-enabled products are available from the world’s
leading manufacturers, enabling you to mix devices from multiple manufacturers.
One cable does it all. Dante does away with heavy, expensive analog or multicore cabling, replacing it with low-
cost, easily-available CAT5e, CAT6, or fiber optic cable for a simple, lightweight, and economical solution. Dante
integrates media and control for your entire system over a single, standard IP network.
Dante systems can easily scale from a simple pairing of a console to a computer, to large capacity networks
running thousands of audio channels. Because Dante uses logical routes instead of physical point-to-point
connections, the network can be expanded and reconfigured at any time with just a few mouse clicks.

11 HARDWARE INSTALLATION
Rack Mounting11.1
The Iyo is 1 RU (1 rack unit/space) high and mounts in a standard 19-inch equipment rack.
Use four mounting screws to fasten the front panel of the Iyo to the 19-inch rack rails.
Support any cables that are attached to the back of the Iyo so that their weight does not put undue stress
on the unit’s connectors.
The Iyo has cooling vents on the side of the unit. Be careful not to obstruct these.
Ethernet Connection11.2
There are 2 RJ-45 Ethernet jacks on the rear of the Iyo, a Primary and a Secondary. A CAT-6 or better network
cable is required for 1000baseT Ethernet operation. For initial setup, connect your Dante network to the Primary
Ethernet jack. See Section on Ethernet connections for information on utilizing the Secondary jack. The cable
length between the Iyo and a network switch should not exceed 100 meters (328 feet)
AC Power11.3
The detachable AC power cord that comes with the Iyo plugs into the IEC connector on the chassis.
The Iyo operates with AC voltages from 90 to 260VAC, 47 to 63Hz. No selection of voltage or frequency is
required, the Iyo’s power supply will automatically adjust.
Use only an AC power source with a protective earth ground.
The Iyo has no power switch. Detach the AC power cord to remove power
Redundant Power Supply11.4
The Iyo can optionally be connected to a second power supply to offer redundancy. The +12VDC power supply
(AudioScience p/n PWR1101) is connected to the Iyo using a locking 2.1mm plug.
Hardware Label11.5
All AudioScience products are shipped with a label showing various hardware specifications. This information can
be helpful in configuring your unit and you will need it if you ever need to return your unit for service.
*MAC address information can be used to help identify your unit in Dante Controller. It will be displayed in the
Device Name field along with the model name.
