How do I connect the Genelec G Two to my audio interface?

Use a balanced XLR cable or an unbalanced RCA cable. Connect one end to the speaker input and the other to your audio interface's output. Ensure the interface is powered off during connection.

What is the optimal placement for the G Two monitors?

Place them at ear height, forming an equilateral triangle with your listening position. Keep them away from walls to avoid bass buildup. Use the rear switches to compensate for boundary effects.

How do I adjust the bass and treble settings?

On the back panel, use the dip switches. Slide them according to your room acoustics. Refer to the manual for recommended settings based on placement.

Can I use the G Two as a home stereo speaker?

Yes, but they are designed for near-field listening. They work well with a preamplifier or audio interface. Note they are active speakers, so no external amplifier is needed.

How do I clean the Genelec G Two speakers?

Unplug the speaker. Wipe the cabinet with a soft, damp cloth. Do not use alcohol or abrasive cleaners. Avoid getting moisture into the driver or ports.

My speaker is not producing sound. What should I check?

First, check the power LED. If off, ensure the power cord is securely connected and the outlet is working. Then verify the audio cable connections and that the input source is active. Try swapping cables.

What is the power consumption in standby mode?

The standby power consumption is less than 0.5 W. The speaker automatically enters standby after 30 minutes without signal.

Are replacement drivers available for the G Two?

Yes, but only through authorized Genelec service partners. Contact Genelec support for information about purchasing spare parts or arranging repairs.

Can I mount the G Two on a wall?

Yes, using optional Genelec wall brackets or mounting adapters. Ensure the bracket supports the speaker's weight (3.3 kg). Follow the mounting instructions carefully.

What is the recommended break-in period for the G Two?

There is no strict break-in period, but the speakers may sound slightly different for the first few hours of use. Play a variety of music at moderate volume to allow the drivers to settle.

Operating Manual

G Two

Active Loudspeaker

General description

The Genelec G Two is a compact two way active loudspeaker designed to produce broad bandwidth sound with high output and low coloration.

Positioning the loudspeaker

Each loudspeaker is supplied with an built-in amplifier unit, signal cables, 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 to the central line of the room and the loudspeakers at equal distance from the walls.

Connections

Before connecting up, ensure that the power switch on the signal source is set to OFF.

Audio input is via an 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. Once the connections have been made, the loudspeakers are ready to be switched on.

ISS Autostart function

When the power switch and the "ISS" switch on the back panel of the loudspeaker are set to "ON", the Intelligent Signal Sensing™ (ISS™) autostart function of the G Two is active. Automatic powering down to standby mode happens after a certain time when playback has ended. The power consumption in standby mode is typically less than 0.5 watts. The playback will automatically resume once an input signal is detected from the source.

There is a slight delay in the automatic powering up. If this is undesirable, the ISS ^TM function can be disabled by setting the “ISS” switch on the back panel to the “OFF” position. In this mode, the loudspeaker is powered on and off using the power switch on the back panel.

Switching off the power indicator LED

The power indicator LED of the G Two can be switched off by turning the "LED OFF" switch on the back panel to "ON".

Level -10 dB switch

The “LEVEL -10 dB” switch reduces the input sensitivity of the G Two by 10 decibels. Select the setting that matches the desired playback volume.

Setting the tone controls

The frequency response of the Genelec G Two can be adjusted to match the acoustic environment by setting the tone control switches on the rear panel. The controls are “Tabletop” “Low Bass” and “Bass”. Table 1 shows some typical settings in various situations. Figure 2 shows the effect of the controls on the frequency response.

Tabletop

This switch is recommended to be switched to "ON" when the loudspeakers are placed on a table or similar surface, such that there is a reflective surface between the loudspeaker and the listener. Such a placement typically causes a boost at certain bass frequencies, which the "Tabletop" function is designed to compensate for.

Low Bass

This switch activates a -4 dB filter to the lowest bass frequencies (65 Hz). This can be used for compensating for heavy and boosted bass in this frequency range.

Table 1: Suggested tone control settings for different acoustical environments

Bass

The “Bass” control offers three attenuation levels for the bass response below 1 kHz, usually necessary when the loudspeakers are placed near room boundaries or other situations when the bass sounds boomy and too dominant. The attenuation levels are -2 dB, -4 dB and -6 dB. The -6 dB attenuation is selected by setting both “Bass” switches to “ON”.

The factory setting for the tone controls is all in the “OFF” position. This setting produces a flat frequency response in the free field, when the loudspeaker is located far from all walls and other acoustically hard boundaries. Always start adjustment by setting all switches to “OFF” 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 between the drivers around the crossover frequency.

Maintain symmetry

Check that the loudspeakers are placed symmetrically and at an equal distance from the listening position. If possible, place the system so that the listening position is on the centerline of the room but not exactly at the center of the room. Place the loudspeakers are at an equal distance from the centerline and also at an equal distance from the listening position.

Minimize reflections

Acoustic reflections from objects close to the loudspeakers like desks, cabinets, computer monitors etc. can cause unwanted blurring of the sound image and also cause frequency response problems. These can be minimized by placing the loudspeaker clear of any hard 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") behind, above and on both sides of the loudspeaker. 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

The G Two offers several mounting options: The Iso-Pod™ (Isolation Positioner/Decoupler™) vibration insulating table stand allows tilting the loudspeaker for correct vertical alignment. On the base of the loudspeaker is a 3/8" UNC threaded hole compatible with a standard microphone stand. On the rear there are threaded holes for Omnimount® 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 Two has 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.
• Do not expose the loudspeaker to water or moisture. Do not place any objects filled with liquid, such as vases on the loudspeaker or near it.
  • This loudspeaker is capable of producing

sound pressure levels in excess of 85dB, which may cause permanent hearing damage.

• Free flow of air behind the loudspeaker is necessary to maintain sufficient cooling. Do not obstruct airflow around the loudspeaker.
• Note that the amplifier is not completely disconnected from the AC mains service unless the mains power cord is removed from the amplifier or the mains outlet.
