the level the monitors. Monitors are
usually also calibrated to deliver the
same level at the listening position. Use
the rotary level adjustment trimmer on
the subwoofer and suitable test signals.
Normally an octave wide pink noise
signal located around 1 kHz is used for
monitors and an octave wide pink noise
around 40 Hz is used for the subwoofer.
If you use a sound level meter, correct
for the weighting – for example using A
weighting in an SPL meter reduces the
level reading for low frequencies relative
to the mid frequencies. We recommend
using an acoustical measurement system
able to show the full frequency response
for improved accuracy.
3.
Adjust the phase of the first subwoofer as
instructed in the chapter “Manual Phase
Adjustment Method”.
4. Repeat phases 1 to 3 with all other
subwoofers in the chain, one by one.
5. When two subwoofers connected in this
way are positioned close to one another,
bass level increases by 6 dB. Three
subwoofers give an SPL increase of 9.5 dB
and four subwoofers 12 dB compared to
a single subwoofer. In order to match the
SPL level of the complete subwoofer chain
with the main monitor system, reduce the
level of all subwoofers accordingly.
Maintenance
There are no user serviceable parts inside
the subwoofer. Maintenance or repair must
only be done by Genelec certified service
personnel.
Guarantee
Genelec guarantees the subwoofers for two
years against manufacturing faults or defects
altering performance. You can extend the
guarantee to five years by registering the
product at www.genelec.com. Refer to the
reseller for full sales and guarantee terms.
Safety Considerations
The 7380A has 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 Genelec certified service
personnel.
•
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
subwoofer is necessary to maintain
sufficient cooling. Do not obstruct airflow
around the subwoofer.
•
This subwoofer is 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.
•
Connect the equipment into an outlet on
a circuit different from that to which the
receiver is connected.
•
Consult the dealer or an experienced
radio/TV technician for help.
Modifications not expressly approved by the
manufacturer could void the user’s authority
to operate the equipment under FCC rules.
