Welcome to the RAVENNA world.

HORUS, your passport to the RAVENNA/AES67 world
If you look closely at the design of modern IP networks and the way information moves around them,
you can begin to see a close resemblance to the way in which we navigate the living, breathing worldthat we inhabit. Subnets become cities and countries and our IP address becomes a passport allowing
us to travel where we are permitted within the digitized world.

Enter into the RAVENNA world.
The RAVENNA Group consists ofindustry leading companies who haveseen the benefits of using a layer3
based, network oriented, real-time
audio format. All RAVENNA partners
share the same vision and mission:
create a multi-vendor, interoperable“eco-system”. Full information can befound on ravenna.alcnetworx.com

RAVENNA Key Features• Sub-millisecond latency• Over 400 bidirectional channels @1FS on one CAT5e• Sample-accurate play-out alignment• QoS support• Utilizes standard protocols on IP layer• Operate on existing networks (PTP-aware switches
recommended)• Operation in shared traffic environment (with QoS
in place)• Easy to configure and maintain RAVENNA networks“Some call 192kHz ‘HD’... We call it standard” - C. Cellier

The Horus Base Unit
Modular by Design

The ability to choose the amount of I/O that each Horus unit is capable of saves money
without diminishing the level of quality. Choose to add any of the option modules
to your Horus and create the ultimate audio interface for your studio, whatever thesize. Once the Horus is fully loaded with option cards, it is capable of achieving anastonishing 200 inputs and 202 outputs @1FS.

Route Signal Anywhere

Horus has been designed so that any input can be routed to any amount of outputs
as required... or at the same time. With comprehensive routing pages accessible both
locally on the touchscreen and by remote access using a standard web browser, Horus
is your answer to signal flow management in your studio.

Your RAVENNA passport, no matter where you come from

Pyramix users are of course our first love, but we are offering any DAW/NLE user theopportunity to take advantage of RAVENNA by using the ASIO (PC) / CoreAudio(Mac) drivers bundled with Horus. So, even if your tool of choice was not
RAVENNA already, it is now.

Green Built

For power-conscious users, Horus has been meticulously designed in order to keep
consumption at an incredible minimum. A Horus running 24 channels of phantom
power enabled preamps will only draw about 60W, making it more affordable to run
than your kitchen lights. A Horus with a full complement of AD8D pre-amps will becloser to 120W.

IOC-HORUS Key Features• 200 inputs and 202 outputs @1FS (dependingon card options)• Fully modular design allows any combinationof IOM option cards for analog and additional
MADI I/O. Full complement of ADA8 provides
48 analog inputs and 48 analog outputs• Works from 44.1kHz to 192kHz (Premium up
to DXD/DSD256)• Signal routing from any input to any 		
combination of outputs• Works as MADI/AES AD/DA for “standard” 		
operation,AND• Works in RAVENNA mode to deliver all I/O 		
through the network• Front panel touch screen for local access• Browser-based remote access using any web
enabled device• Dual or redundant power supply option• Near-zero latency from in to out (<1ms)

The Option Cards

IOM-H-DA8/DA8P
Key Features
The DA8 (up to 192kHz) and theDA8P (up to DXD/DSD256) haveconsistently shown in testing to be
the quietest multichannel D/Aconversion modules available anywhere.

• Auto-mute circuitry for “no-pop” power cycling• Digitally controlled trims for line up procedures• Dynamic range of 127dB (typ)• Easy to set dip switches for international operating levels
