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
preamplier, computer sound card or similar
signal source can be connected, never a high
power signal from the speaker terminals of a
power amplier. 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.
ISS 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 ISS 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.
Model G Three has a switch that can be
used to activate or deactivate the ISS function.
Setting the playback level
The playback level of the loudspeakers has
two basic settings, normal and +10 dB on the
G Four and Five and normal and -10 dB on G
Three. The normal setting is factory default and
the +10 or -10 dB setting can be selected by
turning the corresponding switch on the back
panel to “ON”. This adjustment is used for
matching the loudspeaker to the signal source
so that it plays at a convenient volume.
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 “ON”.
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
‘ON’ when the loudspeakers are placed on a
table, desk or similar surface to minimise the
effect of such reective 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.
Treble
The “Treble” adjustment allows modifying the
high frequency response of the loudspeaker.
The G Three has one setting, -2 dB for
smoothening 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
loudspeakers 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
attenuation is selected by setting both “Bass”
switches to “ON”.
Low Bass
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 “OFF” position. Measure or
listen systematically through the different
combinations of settings to nd 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.
Minimize reflections
Acoustic reections from objects close to the
loudspeakers like desks, cabinets, shelves,
computer monitors etc. can cause unwanted
blurring of the sound image. These can be
