INTRODUCTION TO HORUS
Modular by Design
Horus was designed to give its users an amazing amount of Audio I/O channels, over all the most
commonly deployed formats, while offering an unprecedented level of quality in such a small form
factor.
Providing as standard 64 channels of MADI and 24 channel of AES- EBU I/O, you may choose to add
up to 6 Analog I/O optional modules and one additional MADI extension module to bring the total MADI
capacity to 128 channels and thereby create the ultimate audio interface for your studio, whatever the
size. Once the Horus is fully loaded with option cards, it is capable of achieving an astonishing 176
inputs and 178 outputs @ 1FS There are indeed 2 more output channels than input channels, including
the Stereo Headphone Monitoring.
Route Signal Anywhere
Horus has been designed so that any input can be routed to any number of outputs as required
simultaneously. With comprehensive routing pages accessible both locally on the touchscreen and by
remote access using a standard web browser, Horus is the answer to signal flow management in your
studio.
Green Built
For environmentally-conscious users, Horus has been designed meticulously in order to keep power
consumption at an incredible minimum. A fully loaded Horus running all channels of phantom power will
only draw about 60W, making it more affordable to run than your kitchen lights.
HORUS Key Features
• Up to176 inputs and 178 outputs @1FS
• Works from 44.1 kHz to 192 kHz (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 via the network
• Front panel touch screen for local access
• Front panel Stereo Headphone monitoring
• Browser-based remote access using any web enabled device
• Dual redundant power supply option
• Modular design for analog and additional Digital I/O
• Near-zero latency from in to out (<1ms)
RAVENNA
The Horus has been designed so that the MADI, AES and Analog modules can all feed into or take
their sources from the network over RAVENNA streams, providing up to 176 channels of I/O @ 1FS
over a single CAT5e or CAT6 cable to any other RAVENNA devices on the network.
The RAVENNA connection on the Horus allows for not only audio, but also control and sync information
to flow through as well. Send Timecodes, Wordclock and even GPIO directly to the Horus unit over the
same network as your audio. The RAVENNA port even provides for remote control access to the
configuration and entire routing of the unit itself! Support for: RS-422/LTC/MIDI/GPIO/Video Ref/WCK
RAVENNA is a layer 3 IP based protocol. In environments where existing networks are already in
place, RAVENNA subnets can slip right into place with no additional outlay. In laymen’s terms, this
means that you can connect your Horus to a properly configured network exactly as you would your
PC or Mac, with no additional technology required.
RAVENNA is a “mission critical” protocol, meaning that is has been designed to ensure immensely low
jitter rates and latencies (sub-millisecond) and ensures that every single sample gets to where it needs
to go without fail. Horus also provides a secondary, redundant RAVENNA connection allowing for
uninterrupted use, even when a network connection fails.
Refer to the RAVENNA User Guide and the MassCore-RAVENNA Configuration Guide for more details

Line Output Level calibration
The DA8 and DA8P modules feature both hardware level settings in the form of 4 DIP switches per
output channel and a software fine adjustment to align the Analog Output levels to whatever
local/organization operational levels are mandated.
The Hardware settings will usually be set only once, at product installation, and only if the desired
Operating Line Level differs from the default ex-factory settings of +18 dBu for 0 dBFS.
Procedure for Hardware alignment:
1. Shut down your Horus and make sure that the Horus back panel Power is also switched OFF.
2. Unscrew all DA8 modules that need adjustment.
3. Pull gently out (5-7 cm is enough) to access the DIP Switches. There is one block of 4 dip switches
per channel. Channel 1 is labeled S1, channel 8 is labeled S8.
4. Set the DIP Switches as per the table legend printed on the DA8 module card

Output Level calibration Example:
Assuming your operating Level is 21 dBu for 0 dBFS (typical of French Radio Broadcasters), you
should set the DIP Switches all OFF (DIP Switch positioned to the left, with respect to the picture
below) to set maximum Output Level to +24 dBu (since there is no 21 dBu hardware setting)
Once this is set and the DA modules are screwed back in place. Power up the Horus and go to the
Horus Setup Page>Module, select each D/A module for software calibration.
In this example case set the software attenuation to - 3 dB (see image below), so the overall result ends
up at 21 dBu for a Full Scale signal
The Horus software Output Attenuation range is from -12dB to 0dB

Never attempt to short pin 3 (or pin 2) to Ground on Horus DA's output, since the Horus Line Out driving
circuitry is symmetrical but not floating.
Furthermore, as Unbalanced Inputs are traditionally more sensitive than Balanced Inputs, the - 6dB
Analog level achieved by using only one of the Horus symmetrical outputs, will offer better signal level
adaptation with less risks of overdriving the Unbalanced Inputs connected to the Horus.

Connecting the MADI cable
The MADI port (both the standard one and the optional MADI Expansion module) can be connected
using either Optical or coaxial cabling.
When using Optical cabling, first ensure that you have a clean work area, as
dust and debris can affect the connection if any obstruction is present.
Remove the cap on both the cable and the port and slowly / firmly push the
cable into the receiving port on the Horus unit until it clicks into place.
The MADI optical connector is available in Multimode or Single mode versions.
The Horus is delivered with Multimode connectors unless specified at ordering.
When Using a Coaxial connector. Slowly bring the Male cable up to the female
port, ensuring that the pin in the centre of the male cable lines up with the
receptacle in the female port. Push the connector firmly into place and twist
the sleeve clockwise until it clicks into its locked position.
Maximum recommended cable length is 100 meters
Connecting the Wordclock input/output
The Wordclock connections on the rear of the Horus unit are coaxial BNC’s.
To connect a ordclock source from an external device slowly bring the Male

HORUS KEY FEATURES
Modular analog interfacing
Horus allows the user to choose how many Analog inputs and Analog outputs are required for each
unit. Horus provides a total of six universal I/O slots which can accept a combination of Mic/Line
modules and or Line output cards. Users can configure their Horus with any combination but installing
more than 3 Mic/Line modules requires the installation of the Horus Redundant Power option.
For instance, in a studio environment, 24 A/D (3X IOC-AD8/P) and 8 D/A (IOC-AD8/P) will allow for 24
inputs from the live room and 8 outputs to feed studio monitoring and foldback to the artist. But, with
any combination being possible, this is but one of many scenarios for different combinations.
Modular Device connectivity
Any of the modules listed below (A/D, D/A, MADI, AES, RAVENNA) can be interconnected in any way
the user chooses. Simple and easy routing pages enable the user to source signal from any module,
and send it to any other combination of modules. An A/D Module could feed 8 Channels of AES
Outputs. At the same time, it could feed to 8 MADI channels, or even the RAVENNA stream as well.
This is the function that allows the user operate with the Horus in either a standalone (Analog to
MADI/AES AD/DA) or in RAVENNA Mode, which connects the audio to a RAVENNA network
(described below).
With such a wealth of different outputs, it made sense to apply a “route to” instead of a “route from”
philosophy in the way Horus presents its routing pages. After an initial learning period, you will
understand that this is a much more efficient way to present so many routing options in an easy to
unfold process. So always ask yourself first which output is being considered and then decide what
input signal will feed that output and you will be offered all logical and valid choices at every step. It also
made sense to limit the granularity of routing options to blocks of 8 channels, as a good compromise
between flexibility and complexity.
AD8 / AD8P Remote controlled Mic/Line A/D module
The AD8 (works up to 192 kHz) and the AD8P (works up to DXD/DSD256) are remote controllable,
extremely high-quality Microphone pre-amplifiers with a switch on each channel to route the signal
through dedicated line level circuitry instead. The remote control is achieved over Ethernet, via the
RAVENNA Port at the back of the chassis. With all standard analogue controls also available via
remote (Phantom power on a “per channel” basis, phase invert, HPF) and a Gain stage reaching from 10dB all the way up to +60dB, these modules are not only easy to use, but completely transparent to
listen to as well.
DA8 / DA8P Safety Conscious Analogue Line output Modules
The DA8 (works at sample rates up to 192 kHz) and DA8P (works at sample rates up to DSD) are
specifically designed with the user’s speakers in mind. Incorporating analogue mute circuitry, the DA8/P
modules provide protection against spurious transients that may occur during Sample rate changes and
power cycling “clicks” and “pops” which can damage not only speakers, but also the listener’s ears.
When you add to that a noise floor of less than -125dB, these are the ultimate analog outputs for any
monitoring system.
Redundant power supply options
In broadcast and live applications, nothing can be allowed to fail. By requesting the addition of the
optional redundant power supply to be configured with your Horus interface, you can insure against the
possibility of power supply failure. The redundant power supply takes up no more room and only adds a
few grams to the unit’s total weight.
Redundant versus secondary Power supply (More than 3 Analog Input modules)
There are two configurations for the Horus Redundant / Secondary power supply.
1- Standard redundancy: With two AC power inlet connectors in case of a power failure.
Note: If there are more than 3 AD Modules (up to a maximum of 6 AD). Both power supplies will
have to be physically connected at all times.
2- Secondary power supply: If more than 3 AD cards are specified at Horus order time, Merging will
configure the Horus with a Secondary power supply in order to provide ample current reserve at
Power up and during normal operation with many phantom powered microphones. In that scenario
Horus is wired to only use one AC Power inlet connector.
Note: Do not remove the power sticker on the second covered up inlet power.

MADI 1
This MADI port (switchable between coaxial or optical input connections using the front panel Touch
Screen) provides users with up to 64 channels of MADI I/O for use with the system. The signal sent to
the MADI Outputs (both Coaxial and Optical are available simultaneously) are configurable in blocks of
8 channels and can be sourced from any other module in the Horus.
MADI 2 (Expansion Slot)
An expansion slot allows a second MADI card to be fitted into the Chassis, bringing the total MADI I/O
up to 128 channels. When using the RAVENNA connection to deliver sound to your Pyramix or Ovation
system, this increases the total possible Inputs and outputs in a single Pyramix/Horus combination to a
mind-boggling 176 x 178 channels (combined Analogue/AES/MADI).
AES-EBU
3 x D-SUB25 connectors providing 24 channels (12 AES pairs) of AES-EBU I/O are Included as
standard (as is the MADI 1 module).
Signal routing paradigm
Horus is quite possibly the most flexible audio interface ever designed. Users can literally route any
input signal to any output module. Better yet, it can route any input signal to any combination of output
modules. Routable in blocks of 8 channels, a user can send 8 Mic Inputs to 8 AES outputs. At the same
time these 8 mic inputs can also be sent via the MADI outputs and included in the RAVENNA stream.
RAVENNA IP Audio
Using RAVENNA IP audio, Horus can connect to a standard network, using off the shelf switches and
other IT technology to become a node on a LAN. From that point, any other RAVENNA node can
receive information from and deliver information to, any combination of RAVENNA devices on the
network. It is a revolution in Audio technology and will soon mean the end to costly audio routers and
matrices and allow any facility an immense amount of flexibility. From Broadcast and TV/Film postproduction, to music, live events, theatres, cruise ships and many more applications, the RAVENNA
Enabled Horus interface will reinvent how systems come together.
Synchronization and Control information
Audio is not the only information that can pass down the RAVENNA connection. Horus is able to send
sync and control information such as LTC/MIDI/RS-422 and GPIO down the same wire to and from the
Horus unit.

Installing an additional Horus I/O Module
Installing additional Horus I/O Cards (AD8/AD8P or DA8/DA8P)
Before you start
Place the Horus unit on a hard, dry surface or mount it onto a 19” rack and leave plenty of room
for air convection.
In order to meet the EMC requirements of directives 89/336/EEC and 93/68/EEC, and in order
to obtain the high performance possible for the Horus unit, you must use correctly shielded
cables of good quality for all external connections when installing the Horus unit. For the power
connection, a normal unshielded power cable with a proper ground can be used.
Make sure that your sound system is at a safe volume level.
Hardware Installation
This section will take you through installation of your Horus unit. We will describe how to mount the I/O
modules and the power, audio and digital cable connections that can be accessed on the rear panel.
*PLEASE ENSURE THAT YOUR HORUS UNIT IS SWITCHED OFF BEFORE ATTEMPTING TO
CONNECT ANY CABLES TO THE UNIT.*
If you need to mount an I/O module at a later stage, the following procedure is used.
1. Place the shutdown Horus unit on a dry steady horizontal surface. Remove all cables (including
the power cable).
2. On the back of the Horus unit there are 6 slots for mounting the Analog I/O cards. While all 6
slots are equivalent internally, the 3 top slots are preferable for the AD8 or AD8P Mic/Line input
modules and the lower 3 for the DA8 or DA8P line output modules. On the drawing above, they
are marked as blind Plates for I/O module slots.
3. To remove blind plates from I/O module slots, remove the 2 screws on either side of the plate.
Use a Phillips (cruciform) screwdriver tool size 2
4. Only remove the number of blind plates necessary to fit the I/O module(s). If only one I/O slot is
installed, remove only 1 blind plate. If 2 I/O slots are installed, remove 2 blind plates.
5. It is very important to insert the I/O card horizontally and carefully into the Horus unit. There are
6 set of guides inside the Horus unit to guide the I/O cards correctly into place. Do not use force
in any way to insert the I/O card. This may damage the card. Slide card slowly as picture below
shows.
6. When the cover plate of the I/O card covers the hole created by removing the blind plate, the 2
screws from the blind plate are mounted in the sides of the I/O card. Tighten the screws
carefully and be careful not to damage the threads.
7. After inserting the I/O module, the Horus unit might need to be initialized. If this is the case,
please follow the instructions received with the I/O module.

Installing the Merging PCIe Ethernet Controller Card
NET-MSC-GBEX1
Detailed steps on how to install the NET-MSC-GBEX1 PCIe card in your PC.
1. Power down your PC and switch it off at the wall. Remove the screws holding the top or side of the
case on and carefully slide off the panel.
2. Wearing an anti-static wristband is desirable whenever working with sensitive electrical equipment.
Keeping one hand on a metal part of the case will have the same effect, though you may need both
hands when installing certain items of hardware.
3. Locate an empty PCIe slot and remove the metal backing plate by removing the screw holding it in
place and carefully sliding it up and out. In some cases, there are no backing plates and you will need
to remove a length of metal instead. Do this using a flat-blade screwdriver and/or pliers, taking care to
avoid any sharp edges left behind.
4. Next, remove the NET-MSC-GBEX1 card from its envelope bag and line it up with the vacant PCIe
slot as shown below.

HORUS recommended placement in Rack
Due to confined space in a Rack furniture, adequate spacing (and ordering) between multiple Horus
units will play a significant role on the units temperature. Although Merging has spent considerable time
in optimizing the Horus power consumption in every aspect possible, the units are still drawing an
average of 35W to 45W each. The dissipation of the related heat produced by this consumption is
therefore highly dependent on the airflow and natural air convection around those units.
With highly loaded Horus units (more than 3 I/O Analog modules per unit), Merging recommends a free
space of 2U above and below each unit to ensure adequate cooling of the devices.
HORUS POWER ON
Connecting the Power Cable
The Horus unit runs on 85-240V, 50-60 Hz AC voltage. Excessive voltages can seriously damage the
Horus unit, so make sure that your AC power matches the voltage of your Horus unit. When you
connect the power, use the cable you received with your Horus unit and plug it into a grounded outlet.
For safety and EMC reasons, and to prevent audio hum, the system must be properly grounded. If your
power source does not have a standard three-prong socket, the system must be grounded in another
appropriate manner.
If your Horus unit is equipped with the Redundant Power Supply option, make sure you connect both
mains cables (one to PRI and one to SEC mains plugs on the Horus).
1. Ignite the Horus Back Panel Power Switch
2. Press the Horus Front Panel Power Button
3. The Horus front panel button will turn blue. If the panel button light isn’t steady but appears to flicker,
this may indicate a fault condition and requires immediate shut down.
4. Wait until the Horus is fully started and displaying the Main Home screen.

IO & Sync Menu
The IO and Synchronization menu is where the user can select the source of the Horus reference clock.
It is essential that these settings are configured correctly in order to ensure a clean audio signal through
the Horus unit.
Reference Source
Choose the desired sync source by pressing on the respective Reference
source.
Available Reference Sources are: MADI, Sync or AES
Reference navigation
Selecting a Reference with multiple choices (such as Sync or AES) will enable
the source navigation. The navigation is performed from top to bottom and will
cycle through in this order at each consecutive press. The selection of another
Reference Source will re-select the top entry in the list by default.
PTP Clock
The Precision Time Protocol (PTP) is a protocol used to synchronize
clocks throughout a computer network. Also known as IEEE 1588, it is a
protocol designed to synchronize real-time clocks in the nodes of a distributed
system that communicates using a network. RAVENNA is based on and uses
V2 of this IEEE standardized protocol. PTP Clocks allow for time resolution to
the Nanosecond.
Master: indicates that the current Horus is the PTP Master
Slave: The Horus is slave to another PTP Master
The Horus will always try to be the PTP Master. If multiple Horus’ are used in a
network environment, the Horus set in this order will have the PTP Master
priority, using the Best Master Clock Algorithm (BMCA):
1. Video sync
2. Word Clock
3. AES
4. MADI
5. Internal
6. RAVENNA (always slave unless there is no PTP master available)

button will show the current input signal path it is set for (Mic or Line).
The Line input sensitivity can be adjusted be setting the line gain for each input
of the AD module.
Line Fader of 0 dB, means 0 dBFS for +24 dBu Analog signal level present at
the Line input
Line Fader of + 6 dB, means 0 dBFS for +18 dBu Analog signal level present at
the Line input
Line Fader of + 20 dB, means 0 dBFS for +4 dBu Analog signal level present at
the Line input
Line Fader of + 66 dB, means 0 dBFS for -42 dBu Analog signal level present
at the Line input
Note #1: the MIC and Line inputs are not coupled, meaning that switching from
Mic to Line and vice versa will load its own gain (sensitivity) value
Note #2: The Premium AD converters of Horus have been designed in order to
be able to benefit from the +3.1 dB SA-CD headroom offered by DSD, as per
the scarlet book standard. Therefore a minimum of +6 dB gain is required on
the mic preamp or line input. This gain is applied immediately when the ADs
are switched to DSD (64, 128, 256FS) and is visible in the preamp page. The
gain can be adjusted between +6dB and +66dB in DSD mode. In Line mode,
with a gain of +6dB, an input of +24dBu will generate a signal of +6dB SA-CD,
in Mic mode, with the same gain, an input of +13dBu would generate a signal
of +6dB SA-CD.
To benefit also from this +6dB headroom in DSD on the DA outputs of Horus,
we recommend our users to set the level alignment to -6dB on each DA
module configuration page.
48V
This button will turn on 48V phantom power for the channel. If it is lit, it means
that Phantom power is active. Only active on channels set to Mic.
This warning applies ONLY to the initial RUN 3 production batch of AD8 and AD8P and
has been fixed for all modules shipped starting November 2012:
The 48V power MUST be turned off prior to changing the connection in certain patch
bays. Many such patch bays do short the Hot, Cold or both signals to Ground during
insertion or removal of the Jacks with the risk of deteriorating permanently the protective
resistors in the input of the PreAmp circuitry. If an AD module input circuitry is damaged,
following such a short, it will end up permanently having inaccurate gain levels,
distortion or even no signal at all on some channels. That would require hardware
replacements at your own cost, since such damage is not covered by our warranty.
If you still own one of the original and unmodified RUN 3 AD8/AD8P modules we
recommend that you contact your Merging reseller to organize an update of your
module(s), which Merging is pleased to provide free of charge.
PAD
A -10 dB Pad can be applied inserted in the Mic Preamp circuitry.
Ø
Phase invert button. When lit, it inverts the polarity of the selected input signal.

which are not fitted with the optional MADI expansion card.
Mode:
Sets the MADI mode to either “Standard” (56 audio channels) or “Extended”
(64 channels). To determine which setting(s) you are able to use, please
consult the user manual of the device you are connecting the Horus to in order
to see which (if not both) formats it complies with.
Note: MADI Standard (56) can only be enabled at 1FS (44.1kHz/48kHz) above
1FS we will automatically revert to MADI Extended (64).
Physical Mode:
Choose the input signal to be derived from the Coaxial or Optical MADI
connections at the back of the Horus unit. You can choose to use either or, but
not both at the same time. On the Output side, however, both Coaxial and
Optical outputs are always driven in parallel.
88.2/96k:
Choose between using 48k Frame (Legacy) or 96K Frame (High-speed).
This option is only available for MADI output at 88.2/96kHz sampling rate and
is dependent of the device used in conjunction with the Horus.
For information on why you might want to set this to something other than
Legacy/48K Frame, please consult the user manual of the device you are
connecting Horus to.
Note: Mykerinos users who are connected to the Horus should configure their
Mykerinos Pyramix general settings so that the MADI High Speed mode is
disabled and then set the Horus to 48k Frame (legacy).
Output Sources:
Users can route literally any input signal to any output module. Users can also
route any input signal to any combination of output modules. Signals are

Note:
Horus has no DHCP-server capability neither does the Merging PCIe Ethernet
Controller Card NET-MSC-GBEX1.
By default the Horus IP setting is set to “Auto” configuration mode which gives
an address in the range 169.254.xxx.xxx if no DHCP server is present on the
network. Users are free to put a DHCP server in their RAVENNA network with
a customized address range and the Horus would get an IP address from this
server. Note that our recommended Dell PowerConnect 2816 RAVENNA
switch is configured with DHCP disabled.
Merging recommend the Horus to be configured in “Auto” mode and the
Merging PCIe Ethernet Controller Card NET-MSC-GBEX1 to also be
configured with “Internet Protocol Version 4” with “Obtain an IP automatically”.
You must be aware that when the Horus is started in Maintenance mode the IP
configuration is exclusively done using “Auto” IP settings mode.

Please refer to the technical Horus document to solve the issue of the Horus not restarting.
To make sure that this is the problem you are encountering. Please look through the Horus right side
panel air flow holes, you should see a green light that is blinking rather than steady. If the light is
blinking this means that you should contact Merging support or your local dealer in order to obtain the
technical document on the voltage adjustment procedure.
