speaker. The space adjacent to the amplifier
must either be ventilated or sufficiently large to
dissipate heat so that the ambient temperature
does not rise above 35 degrees Celsius (95°F).
Mounting options
The G Three and G Four offer several mount-
ing options: The Iso-Pod™ (Isolation Posi-
tioner/Decoupler™) vibration insulating table
stand allows tilting the loudspeaker for correct
vertical alignment. There are three mounting
points for the Iso-Pod™ on the back of the
loudspeaker cabinet allowing vertical and sym-
metrical horizontal positioning. On the base of
the loudspeaker is a 3/8” UNC (M10 on the G
Four) threaded hole compatible with a standard
microphone stand. On the rear there are two
sets of threaded holes for Omnimount® and
König & Meyer brackets.
Maintenance
No user serviceable parts are to be found within
the amplifier unit. Any maintenance or repair of
the unit should only be undertaken by qualified
service personnel.
Safety considerations
Although the G Three and G Four have been
designed in accordance with international
safety standards, the following warnings and
cautions should be observed to ensure safe
operation and to maintain the loudspeaker
under safe operating conditions:
• Servicing and adjustment must only be
performed by qualified service personnel.
• The loudspeaker must not be opened.
• Do not use this product with an unearthed
mains cable or an unearthed mains
connection as this may compromise
electrical safety.
• Do not expose the loudspeaker to water or
moisture. Do not place any objects filled with
liquid, such as vases on the loudspeaker or
near it.
• This loudspeaker is capable of producing
sound pressure levels in excess of 85dB,
which may cause permanent hearing
damage.
• Free flow of air behind the loudspeaker is
necessary to maintain sufficient cooling. Do
not obstruct airflow around the loudspeaker.
Note that the amplifier is not completely discon-
nected from the AC mains service unless the
mains power cord is removed from the amplifier
or the mains outlet.

characteristics of the G Four measured at 1 m. The lower curve
shows the system’s power response.

characteristics of the G Three measured at 1 m. The lower curve
shows the system’s power response.
