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 eld monitor-

ing, mobile vans, broadcast and TV control

rooms, surround sound systems and home

studios. Designed as active loudspeak-

ers, they contain drivers, power ampliers,

active crossover lters and protection cir-

cuitry. The Minimum Diraction Enclosure™

(MDE™) and advanced Directivity Control

Waveguide™ (DCW™) technologies provide

excellent frequency balance even in dicult

acoustic environments.

Drivers

The bass driver dimensions are 165 mm (6

1/2”) and 205 mm (8”) for 8040B and 8050B

respectively. The long, ow optimized reex

tube has a large cross sectional area and

terminates with a wide are 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 lters. The crossover fre-

quency 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-o”) allow precise match-

ing of the loudspeakers to any room environ-

ment.

Amplifiers

The amplier 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 con-

necting up, ensure that the mains switch is

o (see gure 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 gure 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 gure 2) are aimed

towards the listening position. Vertical place-

ment 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 cen-

terline.

Minimise reflections

Acoustic reections 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 reective 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.

Genelec 8040B and 8050B Active Monitoring Systems

Minimum clearances

Sucient cooling for the amplier and func-

tioning of the reex 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 amplier must either be ventilated or

suciently 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 align-

ment of the acoustic axis. The stand can be

attached to three mounting points allowing

vertical and symmetrical horizontal position-

ing (see gures 1 and 5).

Genelec 8040B and 8050B can be tted

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 secur-

ing 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 gure 1). A screwdriver is needed for

the adjustment. The manufacturer’s default

setting for this control is -6 dBu (fully clock-

wise) which gives an SPL of 100 dB @1m with

-6 dBu input level.

ISSTM autostart function

When the power switch on the loudspeaker

is set to “ON”, the Intelligent Signal Sens-

ingTM (ISSTM) autostart function of the loud-

speaker is active. Automatic powering down

to standby mode happens after a certain time

when playback has ended. The power con-

sumption in standby mode is typically less

than 0.5 watts. The playback will automati-

cally 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 pow-

ered on and o 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 acous-

tic environment. The adjustment is carried

out by setting the three tone control switch

groups “treble tilt”, “bass tilt” and “bass roll-

o” on the rear panel of the amplier. There is

also a special “desktop low frequency” tone

control which gives an attenuation of 4 dB at

160 Hz to compensate the eect 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 at anechoic response.

Bass roll-off control

Bass roll-o (rst switch group from the left)

aects the low frequency roll-o of the loud-

speaker and attenuates its energy output

near the cut-o frequency. Attenuation levels

of -2, -4 or -6 dB can be selected.
