Do not use this apparatus near water. Do not expose
this apparatus to drips or splashes. Do not place
any objects filled with liquids, such as vases, on the
apparatus.
Do not install near any heat sources such as radia-
tors, heat registers, stoves, or other apparatus
(including amplifiers) that produce heat. No naked
flames, such as lighted candles, should be placed
on the apparatus. Do not install the apparatus in a
confined space such as a book case or similar unit.
Do not block any ventilation openings.
Ensure that foreign objects and liquids cannot get
into the equipment.
Install in accordance with the manufacturer’s
instructions. Only use attachments/accessories
specified by the manufacturer. Use only with the
cart, stand, tripod, bracket or table specified by the
manufacturer, or sold with the apparatus. When a
cart is used, use caution when moving the cart/
apparatus combination to avoid injury from
tip-over.
The apparatus should be located close enough to
the AC outlet so that you can easily grasp the power
cordplug at anytime.
The mains plug, the appliance coupler or the mains
switch is used as the disconnect device. Either
device
shall remain readily operable when the apparatus is
installed or used.
Unplug the apparatus from the wall outlet before
cleaning. Do not use liquid cleaners or aerosol
cleaners. Use a damp cloth for cleaning. Do not
attempt to service this product yourself, as opening
or removing covers may expose you to dangerous
voltage or other hazards. Refer all servicing to quali-
fied service personal. Servicing is required when
the apparatus has been damaged in any way, such
as power-supply cord or plug damaged, liquid has
been spilled or objects have fallen into the appara-
tus, the apparatus has been exposed to rain or
moisture, does not operate normally or has been
dropped.
The equipment may only be used for the purpose
described in the operation instructions. Never carry
out any work on the equipment other than as speci-
fied in the operating manual. Never push objects of
any kind into this product through openings, as they
may touch dangerous voltage points or short-cut
parts, which could result in a fire or electric shock.
Children should never use the apparatus without
close adult supervision.
WARNING: excessive sound pressure levels can
cause hearing loss.
This product should be operated only from the
power source indicated on the apparatus or in the
operating instructions. If you are not sure of the
type of power supply to the premises where the
equipment is to be used, consult your product
dealer or local power company.
Do not defeat the safety purpose of the polarised or
grounding-type plug. A polarised plug has two
blades with one wider than the other. A grounding
type plug has two blades and a third grounding
prong. The wide blade or the third prong is provided
for your safety. If the provided plug does not fit into
your outlet, consult an electrician for replacement
of the obsolete outlet.
Connect Class I construction apparatus to an AC
outlet with a protective grounding connection.
Do not overload wall outlets, extension cords or
integral convenience receptacles, as this can result
in a risk of fire or electric shock.
Protect the power cord from being walked on or
pinched, particularly at plugs, convenience recep-
tacles and the point where they exit from the appa-
ratus. Unplug this apparatus during lightning
storms or when unused for long periods of time.
POWER SUPPLY AND POWER CORD REQUIRE-
MENTS:
Power supply class I grounding requirements:
For protection from fault currents, the equipment
shall be connected to a grounding terminal. Plug
the system power cord into an AC outlet that
provides a ground connection. Substitute cords
may not provide adequate fault protection. Only use
the power cord supplied with this product or an
authorized/equivalent replacement

To create a Loudspeaker Library file
To create a Loudspeaker Library file
Please do the following:
• Enter Developer mode
• Use the output channels starting at output one (1, 2, 3, .. and not 4, 5, 6)
• Mute all outputs that are not part of the system (for a one way use out 1 and mute the rest)
• You can define one-way, multi-way systems, setup a one loudspeaker of a stereo set
• Set-up the DSP to your liking for one system.
• Turn off "Show full graphics" for administrator mode. (The administrator needs it see the right skin)
• Name each output appropriately with clear labels that enable an easy check by the administrators
• Store the setting with a name starting with # in the highest position on the device (i.e. 100, 99, 98, 97,
• Enter Administrator mode
• Click on the appropriate loudspeaker icon for the output channel that you want to load the loudspeaker
to. This does not have to start at channel 1. (e.g. it is possible to define a two way loudspeaker, which must
be done on output 1 and 2, and to load that to output 5 and 6 later)
• Select the appropriate loudspeaker file from the pull down list
• Check for each output if the correct signal is applied to that channel
• Unmute the channels and slowly turn up the signal and check to make sure that each driver gets the
right signal
