System
The GENELEC 8040B and 8050B are two way active monitoring loudspeakers designed to produce high SPL output, low coloration and broad bandwidth in a small enclosure size. They are suitable for a wide variety of tasks, such as near field monitoring, mobile vans, broadcast and TV control rooms, surround sound systems and home studios. Designed as active loudspeakers, they contain drivers, power amplifiers, active crossover filters and protection circuitry. The Minimum Diffraction Enclosure™ (MDE™) and advanced Directivity Control Waveguide™ (DCW™) technologies provide excellent frequency balance even in difficult acoustic environments.
Drivers
The bass driver dimensions are 165 mm (6 1/2") and 205 mm (8") for 8040B and 8050B respectively. The long, flow optimized reflex tube has a large cross sectional area and terminates with a wide flare at the back of the enclosure. The high frequency driver is a 19 mm (3/4") metal dome on the 8040B and a 25 mm (1") metal dome on the 8050B. Both drivers are magnetically shielded.
Crossover
The active crossover network consists of two parallel bandpass filters. The crossover frequency is 3.0 kHz on the 8040B and 1.8 kHz on the 8050B. The active crossover controls ("treble tilt", "desktop low frequency", "bass tilt" and "bass roll-off") allow precise matching of the loudspeakers to any room environment.
Amplifiers
The amplifier unit is mounted in the rear of the loudspeaker enclosure. The unit incorporates special circuitry for driver thermal overload protection. Variable input sensitivity allows accurate level matching to console output section.
Connections
Each loudspeaker is supplied with a mains cable and an operating manual. Before connecting up, ensure that the mains switch is off (see figure 1). Audio input is via a 10 kOhm balanced XLR connector, but unbalanced leads may be used as long as pin 3 is grounded to pin 1 of the XLR (see figure 3). Once the connections have been made, the loudspeakers are ready to be switched on.
Mounting considerations Align the loudspeakers correctly
Always place the loudspeakers so that their acoustic axes (see figure 2) 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 colouration and 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 vibration insulating Isolation Positioner/Decoupler™ (Iso-Pod™) 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 (see figures 1 and 5).
Genelec 8040B and 8050B can be fitted to Omnimount® Series 30 (8040B) and 60 (8050B) and König & Meyer loudspeaker mounts on two sets of M6x10 mm threaded holes on the back of the enclosure. On the base of the enclosure is an M10x10 mm threaded hole which can be used for securing the loudspeaker to its base. Do not use this thread for mounting the loudspeaker on a microphone stand which has a 3/8" UNC thread.
Setting the input sensitivity
The input sensitivity of the loudspeakers can be matched to the output of the mixing console, or other source, by adjusting the input sensitivity control on the rear panel (see figure 1). A screwdriver is needed for the adjustment. The manufacturer's default setting for this control is -6 dBu (fully clockwise) which gives an SPL of 100 dB @1m with -6 dBu input level.
ISS ^TM autostart function
When the power switch on the loudspeaker is set to "ON", the Intelligent Signal Sensing™ (ISS™) autostart function of the loudspeaker 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™ function can be disabled by setting the "ISS DISABLE" switch on the back panel to "ON" position. In this mode, the monitor is powered on and off using the power switch on the back panel.
Setting the tone controls
The frequency response of the system may also have to be adjusted to match the acoustic environment. The adjustment is carried out by setting the three tone control switch groups "treble tilt", "bass tilt" and "bass roll-off" on the rear panel of the amplifier. There is also a special "desktop low frequency" tone control which gives an attenuation of 4 dB at 160 Hz to compensate the effect of a mixing console, desk or other reflective surface between the listener and the loudspeaker. The factory settings for these controls are all "OFF" to give a flat anechoic response.
Bass roll-off control
Bass roll-off (first switch group from the left) affects the low frequency roll-off of the loudspeaker and attenuates its energy output near the cut-off frequency. Attenuation levels of -2, -4 or -6 dB can be selected.

Desktop low frequency control
The desktop low frequency control (fifth switch of first switch group from the left) attenuates the bass frequencies around 160 Hz by 4 dB (see figures 7 and 9). 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.
Bass tilt control
The bass tilt control switches (second switch group from the left) offer three attenuation levels for the bass response below 800 Hz, usually necessary when the loudspeakers are placed near room boundaries. The attenuation levels are -2 dB, -4 dB and -6 dB.
Treble tilt control
Treble tilt (third switch group from the left) allows adjusting the treble response above 5 kHz by +2, -2, or -4 dB, which can be used for correcting an excessively bright or dull sounding system.
An acoustic measuring system such as WinMLS is recommended for analyzing the effects of the adjustments, however, care-
ful 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. Figures 7 and 9 show the effect of the controls on the anechoic response.
Always start adjustment by setting all switches to "OFF" position. Then set only one switch per group to the "ON" position to select the desired adjustment. If more than one switch is set to "ON" (within one switch group) the attenuation value is not accurate.
Measure or listen systematically through the different combinations of settings to find the best frequency balance.
Maintenance
No user serviceable parts are to be found within the loudspeaker cabinet or the amplifier unit. Any maintenance or repair of the loudspeaker should only be undertaken by qualified service personnel.
Safety considerations
Although the 8040B and 8050B have been designed in accordance with international safety standards, to ensure safe operation and to maintain the loudspeaker under safe operating conditions, the following warnings and cautions must be observed:
• 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 lead to personal injury.
• To prevent fire or electric shock, do not expose the unit to water or moisture. Do not place any objects filled with liquid, such as vases on the loudspeaker or near it.
• 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.
• Free flow of air behind the loudspeaker is necessary to maintain sufficient cooling. Do not obstruct airflow around the loudspeakers.
- 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.
WARNING!
Genelec 8040B and 8050B loudspeakers are capable of producing sound pressure levels in excess of 85 dB, which may cause permanent hearing damage.
