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
