General description
Genelec G Three, G Four and G Five are two
way active loudspeakers designed to produce
broad bandwidth sound with high output and
low coloration.
Positioning the loudspeaker
Each loudspeaker is supplied with a built-in
amplifier unit, mains cable and an operating
manual. After unpacking, place the loudspeakers in their required listening positions, pointing them to the center of the listening area. If
possible, place the listening position along the
middle axis of the room and the loudspeakers
at equal distance from the side walls.
Connections
Before connecting up, ensure that the power
switches on the loudspeakers and the signal
source are set to OFF. The power switch
is located on the back panel of the loudspeaker. Do not connect the loudspeaker to an
unearthed mains supply or using an unearthed
mains cable.
Audio input is via a 10 kOhm balanced female
XLR connector or unbalanced RCA connector.
Only line level audio signal from a preamplifier,
computer sound card or similar signal source
can be connected, never a high power signal
from the speaker terminals of a power amplifier.
It is possible to connect two audio sources to
the loudspeakers at the same time using both
connectors, as long as only one source is used
at a time.
Once the connections have been made, the
loudspeakers are ready to be switched on.
Autostart function
Genelec G Three, G Four and G Five a have a
power switch on the back panel. Set this switch
to “OFF” when the loudspeakers are left unused
for several days or when connecting or disconnecting any cables in the system.
When the switch is set to “ON”, the signal
sensing Autostart function of the loudspeakers
powers them up when playback begins. Automatic powering down of the loudspeakers happens one hour after the playback has ended
and the loudspeakers go to standby mode. The
power consumption in standby mode is less
than 0.5 watts. The loudspeaker will automatically and rapidly start once an input signal is
detected from the source.
Setting the playback level
The playback level of theloudspeakers has two
basic settings, normal and +10 dB. The normal
setting is factory default and the +10 dB setting
can be selected by turning the “LEVEL +10 dB”
switch on the back panel to “1”. This makes the
loudspeakers play louder, which is useful if the
signal level is low.
Switching off the power
indicator LED
The power indicator LED can be switched off
by turning the “LED OFF” switch on the back
panel to “1”.
Setting the tone controls
The frequency response of Genelec G Three,
G Four and G Five can be adjusted to match
the acoustic environment by setting the tone
control switches on the rear panel. The controls
are “Tabletop”, “Treble”, “Bass” and “Low Bass”.

dominant. The attenuation levels are -2 dB, -4
dB and -6 dB. On the G Three, the -6 dB attenuation is selected by setting both “Bass” switches
to “1”.

The Low Bass control provides bass attenuation at the lowest frequencies of the loudspeaker’s bass reproduction. This may be necessary
if these deep bass frequencies sound disproportionally strong. The G Three has one setting,
-4 dB and the G Four and G Five provide three
attenuation levels: -2 dB, -4 dB and -6 dB.

The factory setting for all tone controls is “0”
to give a flat anechoic frequency response.
Always start adjustment by setting all switches
to “0” position. Measure or listen systematically
through the different combinations of settings to
find the best tonal balance.
Mounting considerations
Align the loudspeakers correctly
Always place the loudspeakers so that they are
aimed towards the listening position. Vertical
placement is preferable, as it minimizes acoustical cancellation problems around the crossover frequency.
Maintain symmetry
Check that the loudspeakers are placed symmetrically, and at an equal distance from
nearby walls. The distance between the listening position and each loudspeaker should also
be identical. If possible, place the system so
that the listening position is on the centerline of
the room but not in the middle of the front-back
room dimension.
Table 1. Suggested tone control settings in some typical situations
Table 1 shows some typical settings in various
situations. Figures 3, 5 and 7 show the effect of
the controls on the frequency response.
The “Treble” adjustment allows modifying the
high frequency response of the loudspeaker.
The G Three has one setting, -2 dB for smooth-

It is recommended to activate this switch to ‘1’

such reflective surfaces between the loudspeakers and the listener.
Such a placement typically causes a boost in
one region of the bass spectrum. The “Tabletop”
control compensates for this unwanted sound
colouration.
The “Bass” control offers three attenuation
levels for the bass response in frequencies
below 1 kHz, usually necessary when the loudspeakers are placed near room boundaries

Minimize reflections
Acoustic reflections from objects close to the
loudspeakers like desks, cabinets, shelves,
computer monitors etc. can cause unwanted
blurring of the sound image. These can be minimized by placing the loudspeaker clear of reflective surfaces.
Minimum clearances
Sufficient cooling for the amplifier and functioning of the reflex port must be ensured if the
loudspeaker is installed in a restricted space
such as a cabinet or integrated into a wall
structure. The surroundings of the loudspeaker
must always be open to the listening room with
a minimum clearance of 5 centimeters (2 in)
behind, above and on both sides of the loud-
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).
WARNING!
This equipment is capable of producing sound
pressure levels in excess of 85 dB, which may
cause permanent hearing damage.
Mounting options
G Three, G Four and G Five offer several
mounting options: The Iso-Pod™ (Isolation
Positioner/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
symmetrical horizontal positioning. On the base
of the loudspeaker is a 3/8” UNC (M10 on the G
Four and G Five) 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 85
dB, 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.
