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 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 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”.

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 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 mini-

mized by placing the loudspeaker clear of reﬂec-

tive surfaces.

Minimum clearances

Sufﬁcient cooling for the ampliﬁer and function-

ing 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-
