8020D Active Monitoring System

General description

The bi-amplified GENELEC 8020D is a compact two-way active monitoring loudspeaker designed for near-field monitoring, mobile vans, broadcast and TV control rooms, surround sound systems, home studios, multimedia applications and also for use with computer soundcards. As an active loudspeaker, it contains drivers, power amplifiers, active crossover filters and protection circuitry.
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 WaveguideTM (DCWTM), this design provides excellent frequency balance in difficult acoustic environments. If necessary, the bass response of the 8020D can be extended with a Genelec subwoofer.

Positioning the loudspeaker
Each 8020D has an integrated amplifier unit, mains cable and an operating manual. After unpacking, place the loudspeaker in its required listening position, taking note of the line of the acoustic axis. The axes of all loudspeakers should converge at ear height at the listening position (see Figure 1).

Connections
Before connecting up, ensure that the loudspeakers and the signal source have been switched off. The power switch of the 8020D 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 unearthed mains supply or use an unearthed mains cable. The mains input accepts a wide range of voltages: 100-240 V AC 50-60 Hz. Audio input is via a 10 kOhm balanced female XLR connector. An unbalanced source may be used as long as pin 3 is grounded to pin 1 at the unbalanced source connector (see Figure 2). Never connect the 8020D 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.

ISSTM autostart function
When the power switch and the “ISS” switch on the back panel of the loudspeaker are set to “ON”, the Intelligent Signal SensingTM (ISSTM) autostart function of the 8020D 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 ISSTM function can be disabled by setting the “ISS” switch on the back panel to the “OFF” position. In this mode, the monitor is powered on and off using the power switch on the back panel.

Sensitivity control
The input sensitivity of the 8020D can be matched to the output of the signal source by adjusting the rotary sensitivity control on the back panel.

Setting the tone controls
The frequency response of the Genelec 8020D can be adjusted to match the acoustic environment by setting the tone control switches on the rear panel. The controls are “Desktop 200 Hz”, “Treble Tilt”, “Bass Tilt” and “Bass Roll- Off”. An acoustic measuring system is recommended for analyzing the effects of the adjustments, however, careful listening with suitable test recordings can also lead to good results. Table 1 shows some examples of typical settings in various situations. Figure 4 shows the effect of the controls on the anechoic response.

Desktop 200 Hz
The desktop low-frequency control (Switch 2) attenuates the bass frequencies around 200 Hz by 4 dB. This feature is designed to compensate for the boost often occurring at this frequency range when the loudspeaker is placed upon a meter bridge, table or similar reflective surface.

Treble Tilt
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
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 6 “ON”), -4 dB (switch 7 “ON”) and -6 dB (both switches “ON”).
Bass Roll-Off
Bass Roll-Off (switch 4) activates a -4 dB filter to the lowest bass frequencies (65 Hz). This can be used for compensating excessively heavy bass reproduction typically caused by loudspeaker placement near room boundaries. The factory setting for all tone controls is “OFF” to give a flat anechoic response. Always start adjustment by setting all switches to the “OFF” position. Measure or listen systematically through the different combinations of settings to find the best frequency balance.

Mounting considerations

Align the loudspeakers correctly
Always place the loudspeakers so that their acoustic axes (see Figure 1) are aimed towards the listening position. Vertical placement is preferred, as it minimises acoustical cancellation problems 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 and the loudspeakers are placed at an equal distance from the centerline.
Minimise reflections
Acoustic reflections from objects close to the loudspeakers like desks, cabinets, computer monitors etc. can cause unwanted colouration of the sound image. This can be minimised by placing the loudspeaker clear of reflective surfaces. For instance, putting the loudspeakers on stands behind and above the mixing console and tilting them down to point the acoustic axes to ear level at the listening position usually gives a better result than placing the loudspeakers on the meter bridge.
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 8020D offers several mounting options: The Iso-Pod™ (Isolation Positioner/Decoupler™) vibration-insulating table stand allows tilting the loudspeaker for correct alignment of the acoustic axis. On the base of the loudspeaker is a 3/8 in UNC threaded hole compatible with a standard microphone stand. On the rear, there are two M6x10 mm threaded holes for wall or ceiling brackets or the keyhole wall mount adapter provided with the loudspeaker.

Maintenance

• No user-serviceable parts are to be found within the loudspeaker. Any maintenance or repair of the 8020D must only be undertaken by qualified service personnel.

Safety considerations

Although the 8020D has been designed by 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.
