IMPORTANT SAFETY AND
INSTALLATION INSTRUCTION
SAVE THESE INSTRUCTIONS
INSTRUCTIONS PERTAINING TO RISK OF FIRE, ELECTRIC
SHOCK, OR INJURY TO PERSONS
WARNING –when using electric products, basic precautions should be followed, including the following:
1. Read all of the safety and installations instructions and explanation of graphic symbols before using
the product.
2. The product must be grounded. If it should malfunction or breakdown, grounding provides a path of
least resistance or electric current to reduce the risk of electric shock. This product is equipped with a
power supply cord having an equipment-grounding conductor and a grounding plug. The plug must be
plugged into an appropriate outlet which is properly installed and grounded in accordance with all local
codes and ordinances.
DANGER –Improper connection of the equipment-grounding can result in a risk of electric shock. Do
not modify the plug provided with the product –if it will not fit the outlet have a proper outlet installed
by a qualified electrician. Do not use an adapter that defeats the function of the equipment-grounding
conductor. If you are in doubt as to whether the product is properly grounded, check with a qualified
serviceman or electrician.
3. Do not use this product near water –for example, near a bathtub, washbowl, kitchen sink, in a wet
basement, or near a swimming pool, or the like.
4. This product should only be used with a stand or cart that is recommended by the manufacture.
5. This product, either alone or in combination with an amplifier and speakers or headphones, may be
capable of producing sound levels that could cause permanent hearing loss. Do not operate at a high
volume level or at a level that is uncomfortable. If you experience any hearing loss or ringing in the
ears, you should consult an audiologist.
6. The product should be located so that its location or position does not interfere with its proper
ventilation.
7. The product should be located away from heat sources such as radiators, heat registers, or other
products that produce heat.
8. The product should be connected to a power supply only of the type described in the operating
instructions or as marked on the product.
9. The power-supply cord of the product should be unplugged from the outlet when left unused for a
long period of time. When unplugging the power supply, do not pull on the cord, but grasp it by the
plug.
10. Care should be taken so that objects do not fall and liquids are not spilled into the enclosure through
openings.
11. The product should be serviced by qualified service personnel when: A. The power supply cord or
plug has been damaged. Objects have fallen, or liquid has spilled into the product, or C. The product
has been exposed to rain, or D. The product does not appear to be operating normally or exhibits a

www.merging.com/horus Page 5
Horus User Manual
marked change in performance, or E. The product has been dropped, or the enclosure damaged.
12. Do not attempt to service the product beyond that described in the user maintenance instructions.
All other servicing should be referred to qualified service personnel.
13. WARNING - Do not place objects on the power supply cord, or place the product in a position
where anyone could trip over, walk on, or roll anything over cords of any type. Do not allow the
product to rest on or be installed over cords of any type. Improper installations of this type create the
possibility of a fire hazard and/or personal injury.
The lightning flash with arrowhead symbol, within an equilateral triangle, is
intended to alert the user to the presence of uninsulated "dangerous voltage"
within the product's enclosure that may be of sufficient magnitude to constitute a risk
of electric shock to persons.
The exclamation point within an equilateral triangle is intended to alert the user
to the presence of important operating and maintenance (servicing) instructions
in the literature accompanying the product.

Gain behavior of the Direct Out section
As the Direct Out output is taken just after the Mic-pre analog section, the gain adjustments are not as
smooth and linear as after the digital conversion. The figure below shows the behaviour of the gain on
the Direct Out (in blue) compared to the gain on the digital side (in red).
Note: on the Direct Out the maximum available gain is + 40.1 dB.

Line Output Level calibration
The DA8 and DA8P modules feature both hardware level settings and a software fine adjustment to
align the Analog Output levels to whatever local/organization operational levels are mandated.
On DA8/DA8P cards from run 7 upwards, the hardware level setting is done via software through the
option “max output level” in each DA’s setting page, allowing either + 24 dBu or 18 dBu max level.
On DA8/DA8P cards prior to run 7 the hardware level setting is in the form of 4 DIP switches per output
channel
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 (for DA8 prior to run 7):
