GENELEC 4010A Active Loudspeaker

Product Information: Genelec 4010A Active Loudspeaker

The Genelec 4010A is a bi-amplified, compact two-way active loudspeaker designed for fixed installations. It includes drivers, power amplifiers, active crossover filters, and protection circuitry. The loudspeaker enclosure is made of die-cast aluminum and shaped to reduce edge diffraction, providing excellent frequency balance in difficult acoustic environments. The 4010A is designed for indoor use only, in temperatures between 15 to 35 degrees Celsius and relative humidity between 20% and 90%. Each 4010A is supplied with a mains cable, a 3-pin connector for audio signal, a keyhole type wall mount, and an operating manual.

Product Usage Instructions:

1. Connect the audio signal cable to the 3-pole plug provided with the loudspeaker, and secure the connections by tightening the screws on each pole. Push the plug into the connector on the loudspeaker.
2. Connect the mains cables only after you have completed connecting audio signal cabling.
3. Never connect the 4010A to the loudspeaker outputs of a power amplifier, integrated amplifier, or receiver.
4. When all audio connections are completed, connect the loudspeakers to mains with the supplied mains cables. They will switch on automatically.
5. The 4010A is equipped with Intelligent Signal SensingTM (ISSTM) Autostart function, which automatically turns the amplifier to Standby mode if an input signal has not been detected for approximately 1 hour. 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.
6. If the ISSTM function’s slight delay in automatic powering up is undesirable, disable the ISSTM function by setting the ISS DISABLE switch on the back panel to ON position. In this mode, the loudspeaker is powered on and off using the power switch on the back panel.
7. The input sensitivity (playback level) of the 4010A has two alternative settings: normal and -10 dB. The normal setting is factory default, and the lower, -10 dB setting can be selected by turning the SENSITIVITY -10 dB switch on the back panel to ON.
8. The output levels are 100 dB @ -6dBu and 90 dB @ -6 dBu, respectively. Choose the setting that suits your needs.

Delivery contents
Each 4010A is supplied with a mains cable, a 3-pin connector for audio signal, a keyhole type wallmount and an operating manual.

Connections
Connect the mains cables only after you have completed connecting audio signal cabling. Audio input is via a 10 kOhm balanced connector. The pin sequence of the connector is shown in Figure 2.

Connect the signal cable to the 3-pole plug provided with the loudspeaker and secure the connections by tightening the screws on each pole. Push the plug into the connector on the loudspeaker. Never connect the 4010A to the loudspeaker outputs of a power amplifier, integrated amplifier or receiver. When all audio connections are completed, connect the loudspeakers to mains with the supplied mains cables. They will switch on automatically.

ISSTM Autostart
The 4010A is equipped with Intelligent Signal SensingTM (ISSTM) Autostart function, which automatically turns the amplifier to Standby mode if an input signal has not been detected for approximately 1 hour. 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 ISSTM function can be disabled by setting the “ISS DISABLE” switch on the back panel to “ON” position. In this mode, the loudspeaker is powered on and off using the power switch on the back panel.

Sensitivity control
The input sensitivity (playback level) of the 4010A has two alternative settings, normal and -10 dB. The normal setting is factory default and the lower, -10 dB setting can be selected by turning the “SENSITIVITY -10 dB” switch on the back panel to “ON”. The output levels are 100 dB @ -6dBu and 90 dB @ -6 dBu respectively. Choose the setting that

gives the desired playback level and good resolution of the volume control.

Setting the tone controls
The frequency response of the Genelec 4010A can be adjusted to match the acoustic environment by setting the tone control switches on the rear panel. The controls are “Treble Tilt” and “Bass Tilt”. An acoustic measuring system such as WinMLS or comparable is recommended for analyzing the effects of the adjustments, however, careful listening with suitable test recordings can also lead to good results if a test system is not available. Table 1 shows some examples of typical settings in various situations. Figure 4 shows the effect of the controls on the anechoic response.

Treble Tilt
The Treble Tilt control (switch 3) attenuates the treble response of the loudspeaker at frequencies above 5 kHz by 2 dB, which can be used for smoothening down an excessively bright sounding system.

Bass Tilt
The Bass Tilt control offers three attenuation levels for the bass response of the loudspeaker below 2 kHz, usually necessary when the loudspeakers are placed near a wall or other room boundaries. The attenuation levels are -2 dB (switch 4 “ON”), -4 dB (switch 5 “ON”) and -6 dB (both switches “ON”).

Mounting considerations

Align the loudspeakers correctly
Always place the loudspeakers so that their acoustic axes (see figure 1) are aimed towards the center of the listening area. Only vertical placement is preferred, as it minimises acoustical cancellation problems around the crossover frequency.

Minimise reflections
Acoustic reflections from objects close to the loudspeakers like walls, cabinets etc. can cause unwanted colouration of the sound image. These can be minimised by placing the loudspeaker clear of reflective surfaces.

Minimum clearances
Sufficient clearance for cooling of 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 3 centimeters (13/16”) 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 Genelec 4010A offers several mounting options: On the base of the loudspeaker is a 3/8” UNC threaded hole compatible with a standard microphone stand. On the rear, there are three pairs of threaded holes compatible with Omnimount ®, VESA, and Sanus brackets. A rigid wall bracket provided with the 4010A allows suspending the loudspeaker on a wall in two different angles. See Genelec Accessories Catalogue on www.genelec.com for a complete list of mounting hardware options.

Maintenance
There are no user serviceable parts within the loudspeaker. Any maintenance or repair of the 4010A should only be done by qualified service personnel.

Safety considerations

Although the 4010A has been designed in accordance with international safety standards, the following warnings 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 85 dB, 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.
