Frequently Asked Questions - G3 GENELEC

How do I connect the G3 loudspeaker to my audio source?

Use the balanced XLR female input or the unbalanced RCA input. Connect only line-level signals from a preamplifier, sound card, or similar. Ensure both the loudspeaker and source are switched off before connecting.

What is the Autostart function and how does it work?

The Autostart function automatically powers the loudspeaker on when an audio signal is detected. After one hour of no signal, it enters standby mode consuming less than 0.5 W. It wakes up instantly when playback resumes. The rear power switch must be set to ON for Autostart to operate.

How do I adjust the tone controls for optimal sound?

The rear panel has switches for Tabletop, Treble, Bass, and Low Bass. Start with all switches at '0' (flat response). Then adjust based on placement: for tabletop use, activate Tabletop switch to -4 dB at 200 Hz. Use Treble to tame brightness, Bass to reduce boomy low frequencies, and Low Bass for deep bass control. Refer to the manual's suggested settings table.

What is the correct placement position for the G3?

Place the loudspeakers symmetrically, aimed at the listening position. Maintain equal distance from side walls and between speakers. Keep a minimum 5 cm (2 in) clearance behind, above, and on sides for cooling and reflex port function. Avoid reflective surfaces like desks or shelves. Vertical orientation is recommended.

Can I mount the G3 on a wall or ceiling?

Yes, the G3 has threaded holes on the rear for Omnimount® and König & Meyer brackets. It also has a 3/8" UNC threaded hole on the base for standard microphone stands. Ensure adequate clearance for cooling and port function.

How do I switch off the power indicator LED?

On the rear panel, set the 'LED OFF' switch to '1'. This disables the front LED while the loudspeaker remains operational.

What should I do if the loudspeaker produces no sound?

Check that the power switch is set to ON, the volume source is active, and cables are securely connected. Ensure the source is not muted and is outputting a signal. If using Autostart, verify that the signal is present. If the issue persists, test with a different source or cable.

Is it safe to leave the loudspeaker on standby?

Yes, the standby mode consumes under 0.5 W and is safe. However, if the loudspeaker will be unused for several days, it is recommended to switch the rear power switch to OFF and unplug the mains cable for complete disconnection.

Can I use the G3 with a subwoofer?

The G3 is a full-range active loudspeaker. To integrate a subwoofer, connect the source to the subwoofer first, then use its high-pass outputs to feed the G3. Alternatively, use a line-level crossover. Ensure proper level matching.

How do I clean the loudspeaker?

Use a soft, dry cloth to gently wipe the cabinet and grille. Do not use any liquids, solvents, or abrasive cleaners. Avoid moisture entering the enclosure. The grille is not removable.

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 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 the loudspeakers 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. 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.

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 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 smoothing 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 "1".

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 disproportionately 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.

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).

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.
