2. First calibrate the level between the
subwoofer and all main monitors using
the rotary level adjustment trimmer on the
subwoofer and suitable test signals.
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 in the chain accordingly.
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 7370A 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
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.
