General description
The bi-amplified GENELEC 8030C is a two way active monitoring loudspeaker designed to be small but still have high output, low coloration, and broad bandwidth.
The 8030C is ideal 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 8030C can be extended with a suitable Genelec subwoofer.
Positioning the loudspeaker
Each 8030C monitor is supplied with 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
Connect the audio cables first and the mains power cables only after you have completed the audio cabling. 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 labelled “INPUT”. An unbalanced source may be used as long as pin 3 is grounded to pin 1 at the unbalanced source connector (see Figure 2).
Once the connections have been made, the loudspeakers are ready to be switched on.
ISSTM autostart function
The automatic power saving function ISS (Intelligent Signal Sensing) can be activated by setting the “ISS” switch on the back panel to “ON.” 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. 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 “OFF.” In this mode, the monitor is powered on and off using the power switch on the back panel.
Setting the sensitivity control
The input sensitivity of the loudspeaker can be matched to the output of the audio signal source by adjusting the sensitivity control on the back panel.

shown is RCA output to the XLR input)

Setting the tone controls
The frequency response of the 8030C can be adjusted to match the acoustic environment by setting the tone control switches on the rear panel. The controls are “Desktop”, “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 if a test system is not available. Table 1 shows some typical settings in various situations. Figure 4 shows the effect of the controls on the anechoic response.
Desktop
The desktop low frequency control (Switch 1) attenuates the bass frequencies
around 160 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 (switch 2) attenuates the treble response above 4 kHz by 2 dB,
which can be used for smoothening down an excessively bright sounding system.
Bass Roll-Off
Bass Roll-Off (switch 3) activates a -4 dB filter to the lowest bass
frequencies (55 Hz). This can be used for compensating excessively heavy bass
reproduction typically caused by loudspeaker placement near room boundaries.
Table 1: Suggested tone control settings for differing acoustical environments.
Loudspeaker Mounting Position | Desktop | Treble Tilt | Bass Tilt | Bass Roll-Off |
---|---|---|---|---|
Flat anechoic response | OFF | OFF | OFF | OFF |
Free standing in a damped room | OFF | OFF | OFF | OFF |
Free standing in a reverberant room | OFF | OFF | -2 dB | OFF |
Near field or console bridge | ON | OFF | OFF | OFF |
Near to a wall | OFF | OFF | -4 dB | OFF |
On a desk | ON | OFF | -2 dB | OFF |
Bass Tilt
Bass Tilt offers three attenuation levels for the bass response below 1 kHz,
usually necessary when the loudspeakers are placed near room boundaries. The
attenuation levels are -2 dB (switch 4 “ON”), -4 dB (switch 5 “ON”) and -6 dB
(both switches “ON”).
The factory setting for all tone controls is “OFF” 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.
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 preferable, 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 blurring of the sound
image. These can be minimised by placing the loudspeaker clear of reflective
surfaces. For instance, putting the loudspeakers on stands behind and above
the mixing console usually gives a better result than placing them on the
meter bridge.
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 8030C offers several mounting options: The Iso-Pod™ (Isolation
Positioner/Decoupler™) vibration insulating table stand allows tilting of the
loudspeaker for correct alignment of the acoustic axis. The stand can be
attached to three mounting points allowing vertical and symmetrical horizontal
positioning. 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 20.5 brackets.
Maintenance
No user serviceable parts are to be found within the amplifier unit. Any maintenance or repair of the 8030C unit should only be undertaken by qualified service personnel.
Safety considerations
Although the 8030C 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 as this may compromise 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.
