3.4. User responsibility
3.4.1. Mains connection grounding
Your amplier must be connected to a grounded socket outlet.
3.4.2. Speaker output hazard on amplifiers
Ampliers are capable of producing hazardous output
voltages. To avoid electrical shock, do not touch any exposed
speaker wiring while the amplier is operating. The external
wiring connected to the speaker terminals shall be installed
by a qualied person, or ready-made leads or cords of
appropriate capacity shall be used.
As the power output channels on ampliers produce high
voltage, do not connect or disconnect speaker cables when
the mains power is on.
3.4.3. Radio interference
A sample of this product has been tested and complies with
the limits for the European Electro Magnetic Compatibility
(EMC) directive. This equipment has also been tested and
found to comply with the limits for a Class A digital device,
pursuant to Part 15 of the FCC Rules. These limits are
designed to provide reasonable protection against harmful
interference from electrical equipment. This product uses
radio frequency energy and if not used or installed in
accordance with these operating instructions, may cause
interference to other equipment, such as radio receivers.
This Class A digital apparatus complies with Canadian ICES-003.
Cet appareil numérique de la classe A est conforme à la norme NMB-003
du Canada.
However, there is no guarantee that interference will not
occur in a particular installation. If this equipment does cause
harmful interference to radio or television reception, which
can be determined by turning the equipment on and off, the
user is encouraged to try to correct the interference by one or
more of the following measures:
• Reorient or relocate the antenna.
• Increase the separation between the equipment and
re cei ver.
• Connect the equipment to an outlet on a circuit different
from that to which the receiver is connected.
• Check if the affected unit complies with the EMC limits for
immunity, (CE-labeled). If not, address the problem with
the manufacturer or supplier. All electrical products sold
in the EC must be approved for immunity against
electromagnetic elds, high voltage ashes, and radio
interference.
• Consult the dealer or an experienced radio/TV technician
for help.
3.4.4. Speaker damage
Amplier apparatus is very powerful and can be potentially
dangerous to both loudspeakers and humans alike. Many
loudspeakers can be easily damaged or destroyed by
overpowering them. Always check the speaker’s continuous
and peak power capabilities. Although the ampliers
attenuators can be used to reduce the overall gain, an
increase of the input signal can result in full output power,
which may cause damage to connected speakers.
3.4.5. Maintenance
For safe and reliable operation, the dust lters on both sides
of the front panel, behind the grilles, should be removed and
cleaned regularly to ensure maximum airow through the
device.
If the dust lters are not maintained there will be safety
risks; for example, high internal temperatures could ignite
the dust and start a re. There is also a risk that the unit will
malfunction since it is dependent on constant airow from
front to rear. If the dust lters are not clean and the unit
malfunctions, any resulting problems will not be covered by
the warranty.

7.1. Unpacking
Carefully open the shipping carton and check for any damage to the device or the supplied accessories. Every
Lab.gruppen product is tested and inspected before leaving the factory and should arrive in perfect condition. If
any damage is discovered, please notify the shipping company immediately. Only the consignee may initiate a
claim with the carrier or their insurers for damage incurred during shipping. Save the carton and packing materials
for the carrier’s inspection.
7.1.1. Included in the box
In addition to the D Series device, the shipping carton includes the following items:
• D Series Tesira Quick Start Guide (this document)
• AC mains lead (power cable) with Neutrik® powerCON® connector and AC socket plug according to
ordering selection
• Rear brackets for additional rack support (pair) along with associated mounting hardware
• Connector kit including all needed connectors
• Front grille and dust lter assembly
NOTE: Depending on the model, the connector kit might include more connectors than applicable for the product
you have. Select those connectors required for your unit and application
Please keep the original carton and associated packaging to facilitate shipping of the device should the need arise.
7.2. Mounting
D Series is made for mounting in 19 inch racks. Four screw holes are available for attachment of the amplier to
the racks front rack rail. This device has no top or bottom vents; therefore, units may be stacked directly on top of
one another. Sufcient space should be available at the rear to accommodate connectors and cables. In addition,
allowance must be made for cable or loom bends within a rack.
7.2.1. Rear Mounting
Two rear support brackets, along with associated mounting hardware, are included with the D Series device. It is
strongly recommended that these are used wherever possible. Fit the brackets to the vertical rails at the rear of
the rack. The support brackets are reversible and may be tted to point either to the front or rear of the rack; the
proper orientation depends on the rack depth and position of the rear rack rails.

7.2.2. Mounting front grille
The front grille is shipped on top of the amplier inside the box to protect it during shipping. The front grille adheres
to the amplier with magnets. Hold the front grille with your ngers in each of the side cutouts and slide it gently into
place straight from the front.
NOTE: Always ensure the dust lters behind the detachable front panel are clean to ensure maximum possible
airow. The exterior front panel is held in place by powerful magnets but is easy to detach by using your ngers in the
openings at the each side. To clean the foam lter, detach it from the exterior front and gently use a vacuum cleaner
or gently shake it. Remount with the opposite procedure. Never operate the amplier without the dust lter installed.
