end of the recess with the driver side facing

• Servicing and adjustment must
only be performed by
qualified service personnel.
• Opening the amplifier unit is strictly
prohibited except by qualified
service personnel.
Setting the input sensitivity
Minimum clearances to walls
or other objects
Do not cover the driver side of the subwoofer
or place the subwoofer so that there is less
than 10 centimeters (4") of free space in front
of the grille.
The 7050A is set to the same sensitivity
as the 1029A/2029A/2029B monitors in free
field conditions. However, when placed near
reflecting surfaces the sensitivity typically
needs to be attenuated due to increased
room loading. A typical starting point would
be -4 dB. This is achieved by adjusting the
rotary level control on the amplifier plate. The
use of proper measuring equipment together
with careful listening is highly recommended.
The maximum attenuation is -18 dB.
• Always use a mains power
connection with protective earth.
Failing to do this may lead
to personal injury.
Warning!
Make sure that the space underneath the
subwoofer is clear from obstructions. Thick
carpets may block the ventilation clearance
needed for cooling the amplifier unit.
The reflex port side (opposite of the con-
nector panel side) should always have a
clearance of at least 7,5 centimeters (3") to
any objects to ensure proper functioning of
the reflex port.
This equipment is capable of delivering sound
pressure levels in excess of 85dB, which may
cause permanent hearing damage.
Maintenance
No user serviceable parts are inside the
amplifier unit. Any maintenance of the unit
must only be performed by qualified service
personnel.
Safety considerations
Genelec 7050A subwoofer has been designed
in accordance with international safety stand-
ards. However, to ensure safe operation and
maintain the unit in safe operating condition,
the following warnings and cautions must be
observed:
Flush mounting the subwoofer
Guarantee
If the subwoofer is flush mounted into a wall
or a cabinet, it is important to ensure ampli-
fier cooling and unrestricted airflow from the
reflex port. This can be done by making the
recess 7,5 centimeters (3") wider than the

guarantee against manufacturing faults or
defects that might alter the performance of
the unit. Refer to supplier for full sales and
