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
amplier unit, mains cable and an operating
manual. After unpacking, place the loudspeak-
ers in their required listening positions, point-
ing 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 loud-
speaker. 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 discon-
necting 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. Auto-
matic powering down of the loudspeakers hap-
pens 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 automati-
cally 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 OFFswitch 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”.
Table 1 shows some typical settings in various
situations. Figures 3, 5 and 7 show the effect of
the controls on the frequency response.
Tabletop
It is recommended to activate this switch to ‘1
when the loudspeakers are placed on a table,
desk or similar surface to minimise the effect of
such reflective surfaces between the loudspeak-
ers 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.
Treble
The “Treble” adjustment allows modifying the
high frequency response of the loudspeaker.
The G Three has one setting, -2 dB for smooth-
ening down an excessively bright sounding
system, the G Four and G Five provide two
attenuation levels, -2 dB and -4 dB and one
boost setting, +2 dB.
Bass
The Bass control offers three attenuation
levels for the bass response in frequencies
below 1 kHz, usually necessary when the loud-
speakers are placed near room boundaries
or other situations when the bass sounds too
dominant. The attenuation levels are -2 dB, -4
dB and -6 dB. On the G Three, the -6 dB attenu-
ation is selected by setting both “Bass” switches
to “1”.
Low Bass
The Low Bass control provides bass attenua-
tion at the lowest frequencies of the loudspeak-
er’s bass reproduction. This may be necessary
if these deep bass frequencies sound dispro-
portionally 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 acous-
tical cancellation problems around the crosso-
ver frequency.
Maintain symmetry
Check that the loudspeakers are placed sym-
metrically, and at an equal distance from
nearby walls. The distance between the listen-
ing 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.
Minimize reflections
Acoustic reections from objects close to the
loudspeakers like desks, cabinets, shelves,
computer monitors etc. can cause unwanted
blurring of the sound image. These can be mini-
mized by placing the loudspeaker clear of reflec-
tive surfaces.
Minimum clearances
Sufficient cooling for the amplifier and function-
ing of the reex 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-
