General

The bi-amplified Genelec 4030A is an extremely compact two way active loudspeaker designed for fixed installations. As an active loudspeaker, it contains drivers, power amplifiers, active crossover filters and protection circuitry. The 4030A is designed for indoor use only, in temperatures between 15 to

35 degrees Celsius and relative humidity between

20 % and 90 %.

The MDE™ (Minimum Diffraction Enclosure™) loudspeaker enclosure is made of die-cast aluminium and shaped to reduce edge diffraction.

Combined with the advanced Directivity Control

Waveguide TM (DCW TM ), this design provides excellent frequency balance in difficult acoustic environments.

Positioning the loudspeaker

Each 4030A is supplied with an integrated amplifier unit, mains cable, a 5-pin connector for audio signal and 12 V trigger voltage, a keyhole type wallmount and an operating manual. After unpacking, place the loudspeaker in its required listening position, taking note of the line of the acoustic axis. The axis should be pointed towards the center of the listening area.

Connections

Before connecting up, ensure that the loudspeakers and the signal source have been switched off. The power switch of the 4030A is located on the back panel (see Figure 3). Connect the loudspeaker to an earthed mains connection with the supplied mains cable. Never connect the loudspeaker to an un-

earthed mains supply or using an unearthed mains cable. Audio input is via a 10 kOhm balanced connector. The connector also has two pins for 12 V trigger voltage for power switching. The current fed into the 12 V trigger connection must not exceed

200 mA. The pin sequence of the connector is shown in Figure 2.

Connect the signal cable and 12 V trigger voltage to the 5-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 4030A to the loudspeaker outputs of a power amplifier or an integrated amplifier or receiver.

Once the connections have been made, the loudspeakers are ready to be switched on.

Level control

The input sensitivity of the loudspeaker can be matched to the output of the signal source by adjusting the level control on the rear panel.

Setting the tone controls

The frequency response of the Genelec 4030A can be adjusted to match the acoustic environment by setting the tone control switches on the rear panel. The controls are “Treble Tilt”, “Bass

Tilt” and “Bass Roll-Off”. An acoustic measuring system such as WinMLS or comparable is recom-

to give a flat anechoic response. Always start adjustment by setting all switches to “OFF” position.

Measure or listen systematically through the different combinations of settings to find the best frequency balance.

Treble Tilt

The Treble Tilt control (switch 1) 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.

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.

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 3 “ON”), -4 dB (switch 4 “ON”) and -6 dB (both switches “ON”).

Bass Roll-Off

The Bass Roll-Off (switch 2) activates high-pass filtering at 85 Hz to match the low frequency cutoff of the 4030A to subwoofers using 85 Hz low-pass filtering.

The factory setting for all tone controls is “OFF”

Minimise reflections

Acoustic reflections from objects close to the loudspeakers like walls, cabinets etc. can cause unwanted colouration blurring 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 mini-

mum clearance of 3 centimeters (1 3 /

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 4030A 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 two

M6x10 mm threaded holes for Omnimount ® size

electrical safety.

• 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.

Maintenance

No user serviceable parts are to be found within the amplifier unit. Any maintenance or repair of the

4030A unit should only be undertaken by qualified service personnel.

Guarantee

This product is guaranteed for a period of two years against faults in materials or workmanship. Refer to supplier for full sales and guarantee terms.

Safety considerations

Although the 4030A 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 use this product with an unearthed mains cable or an unear thed mains connection as this may compromise
