should be set to "OFF".
The "LFE +10 dB" function should not be
used in the following cases:
• If the +10 dB LFE gain is already
implemented by another device, for
example, a surround sound processor
or the output matrix of a mixing console.
• When producing an audio format
that does not require the use of +10 dB
gain on the LFE channel.

Additional Information

Positioning Subwoofer in Room
The location of the subwoofer can affect
the frequency response and sound level
dramatically particularly when the room
acoustic effects are strong. Even small
changes in a subwoofer's location can
make a marked difference in the frequency
response. To begin, place the subwoofer
at the front wall slightly offset from the
room center line. Often methodical
experimentation is needed to find the
location giving the flattest frequency
response at the listening location. Usually
the subwoofer is placed close to a wall as
this usually creates the highest output.
Positioning the subwoofer close to a corner
will boost the bass level at lower frequencies
and may also cause asymmetrical spatial
imaging. Measured from the subwoofer's
driver the recommended distance to a wall
is less than 0.6 m (24 in). Cancellations from
the wall are then avoided.
Operating Environment
These subwoofers are designed for
indoor use only. The permissible ambient
temperature is 15-35 degrees Celsius
(50-95°F) and relative humidity 20% to
80% (noncondensing). When the product
has been stored or transported in cool
environment and is taken into a warm room,
wait 0.5-1 hours before opening packing to
prevent condensation of humidity before
connecting to mains power.
Minimum Clearances
Do not cover the grille or place the
subwoofer so that there is less than 0.1
m (4 in) of free space in front of the grille.
The space must be ventilated or sufficiently
large to dissipate heat so that the ambient
temperature does not rise above 35
degrees Celsius (95°F). Make sure that the
space under the subwoofer allows air flow.
Thick carpets may block ventilation needed
for cooling the electronics. The reflex port
opening should have a clearance of at least
7.5 cm (3 in) to ensure functioning of the
reflex port.
Flush Mounting
When the subwoofer is flush mounted in a
wall or cabinet, ensure unrestricted airflow
in the reflex port and amplifier cooling.
Make the recess 7.5 cm (3 in) wider than the
subwoofer. Place the subwoofer to the right
side of the recess if the driver is facing the
room. This leaves sufficient free space at
the reflex port side. The height and depth of
the recess should not be much bigger than
needed for ventilation as this may cause
unwanted acoustic effects.

Maintenance

There are no user serviceable parts inside
the subwoofer. Maintenance or repair must
only be done by a Genelec certified service.
Guarantee
Genelec guarantees the subwoofers for
two years against manufacturing faults or
defects altering performance. Refer to the
reseller for full sales and guarantee terms.

Safety Considerations

The 7360A and 73700A have been designed
in accordance with international safety
standards. To ensure safe operation, the
following warnings and precautions must be
observed:
• Servicing and adjustment must only be
performed by a Genelec certified service.
• The subwoofer enclosure must not be
opened.
• Do not use this product with a mains
cable or mains outlet having no protective
earth (potential equalizing) connection as
doing so may result in personal injury.
• To prevent fire or electric shock, do not
expose the product to water or moisture.
• Do not place objects filled with liquid, such
as vases, on the subwoofer or near it.
• The amplifier is not completely
disconnected from the mains power
unless the mains cable is removed from
the amplifier or the mains outlet.
• Free flow of air behind and around the
Figure 4. Flush mounting the
subwoofer. Note the clearance needed
on the reflex port side.
subwoofer is necessary to maintain
sufficient cooling. Do not obstruct airflow
around the subwoofer.
• These subwoofers are capable of
producing sound pressure levels in
excess of 85 dB, which may cause a
permanent hearing damage.
Compliance to FCC Rules
This device complies with part 15 of the FCC
Rules. Operation is subject to the following
two conditions:
• This device may not cause harmful
interference, and
• This device must accept any interference
received, including interference that may
cause undesired operation.
Note: This equipment has been tested and
found to comply with the limits for a Class B
digital device, pursuant to part 15 of the FCC
Rules. These limits are designed to provide
reasonable protection against harmful
interference in a residential installation.
This equipment generates, uses and can
radiate radio frequency energy and, if not
installed and used in accordance with the
instructions, may cause harmful interference
to radio communications. 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
off and on, the user is encouraged to try to
correct the interference by one or more of
the following measures:
• Reorient or relocate the receiving
antenna.
• Increase the separation between the
equipment and receiver.
