General description

The bi-ampliﬁed GENELEC 8030A is a two way

active monitoring loudspeaker designed to be small

but still have high output, low coloration, and broad

bandwidth.

The 8030A is ideal for near ﬁeld monitoring,

mobile vans, broadcast and TV control rooms, sur-

round sound systems, home studios, multimedia

applications and also for use with computer sound-

cards. As an active loudspeaker, it contains driv-

ers, power ampliﬁers, active crossover ﬁlters and

protection circuitry. The MDE™ (Minimum Diffrac-

tion Enclosure™) loudspeaker enclosure is made

of die-cast aluminium and shaped to reduce edge

diffraction. Combined with the advanced Direc-

tivity Control Waveguide

TM

(DCW

TM

), this design

provides excellent frequency balance in difﬁcult

acoustic environments. If necessary, the bass

response of the 8030A’s can be extended with a

Genelec 7050B or 7060B subwoofer.

Positioning the loudspeaker

Each 8030A 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 acous-

tic 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 mains

switch is off and the volume control fully counter-

clockwise. These controls are located on the front

panel of the loudspeaker. Do not connect the loud-

8030A

Active Monitoring System

speaker 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).

The male XLR “OUTPUT” connector can be

used for daisy-chaining up to six 8030A’s together

or for connecting a Genelec 7050B subwoofer. The

volume control attenuates the signal on this output,

so the ﬁrst “master” loudspeaker on a daisy-chain

can be used to adjust the level on the whole chain.

The volume controls on the “slave” loudspeakers

should be set fully clockwise.

Once the connections have been made, the

loudspeakers are ready to be switched on.

Setting the volume control

The input sensitivity of the loudspeaker can be

matched to the output of the audio signal source by

adjusting the volume control on the front panel.

Setting the tone controls

The frequency response of Genelec 8030A 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 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.

Treble Tilt

Treble Tilt (switch 1) attenuates the treble response

above 5 kHz by 2 dB, which can be used for smooth-

ening down an excessively bright sounding system.

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 3 “ON”), -4

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

Bass Roll-Off

Bass Roll-Off (switch 2) activates high-pass ﬁlter-

ing at 85 Hz to complement the low-pass ﬁlter on

a Genelec 7050B subwoofer. This switch should

always be set to “ON” when using the 8030A with

7050B subwoofers.

The factory setting for all tone controls is “OFF” to

give a ﬂat anechoic response. Always start adjust-

ment by setting all switches to “OFF” position. Mea-

sure 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 acous-

tic axes (see ﬁgure 1) are aimed towards the listen-

ing position. Vertical placement is preferable, as it

minimises acoustical cancellation problems around

the crossover frequency.

Maintain symmetry

Check that the loudspeakers are placed symmetri-

cally and at an equal distance from the listening

position. If possible, place the system so that the lis-

tening 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 loud-

speakers like desks, cabinets, computer monitors

etc. can cause unwanted blurring of the sound

image. These can be minimised by placing the loud-

speaker 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 function-

ing 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 loud-

speaker. 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 8030A 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. 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

8030A unit should only be undertaken by qualiﬁed

service personnel.

Safety considerations

Although the 8030A has been designed in accord-

ance with international safety standards, the fol-

lowing warnings and cautions should be observed

to ensure safe operation and to maintain the loud-

speaker 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 mois-

ture. 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 ow of air behind the loudspeaker is nec-

essary to maintain sufficient cooling. Do not

obstruct airﬂow around the loudspeaker.

• Note that the ampliﬁer is not completely discon-

nected from the AC mains service unless the

mains power cord is removed from the ampliﬁer

or the mains outlet.

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.

Réglage des commandes de

tonalité

La réponse en fréquences de la 8030A peut s’ac-

corder à l’environnement acoustique en ajustant

les commandes de tonalité sur l’arrière de l’en-

ceinte. Les commandes sont Treble Tilt, Bass

Tilt, et Bass Roll-Off. GENELEC recommande

l’utilisation d’un système de mesure acoustique

tel WinMLS pour analyser l’effet des ajustements,

bien que l’écoute critique avec un signal appro-

prié peut aussi donner d’excellents résultats si

un système de mesure n’était pas disponible. Le

tableau 1 montre des ajustements typiques dans

différentes situations. L’illustration 4 montre l’effet

des commandes sur la réponse en chambre ané-

choïque.

Commande Treble Tilt

Le sélecteur Treble tilt (commutateur 1) atténue de

2 dB la réponse en fréquence au delà de 5 kHz, ce

qui permet d’adoucir les systèmes trop stridents.

Commande Bass Tilt

Le circuit Bass Tilt procure trois niveaux d’atténua-

tion pour la réponse en basses fréquences sous 1

kHz, ce qui est habituellement nécessaire lorsque

l’enceinte est placée près des murs de la pièce. Les

niveaux d’atténuation disponibles sont -2 dB (com-

mutateur 3 en position ON), -4 dB (commutateur

4 en position ON), -6 dB (commutateurs 3 et 4 en

position ON).

Herkkyyden säätö

Kaiuttimen ottoliitännän herkkyys (äänenvoi-

makkuus) voidaan säätää sopivaksi etuseinän

oikeassa alakulmassa olevalla voimakkuussääti-

mellä.

Taajuusvastesäätöjen käyttö

Kaiuttimen taajuusvastetta voidaan muokata kuun-

telutilan akustisista ominaisuuksista ja kaiuttimien

sijoituksesta johtuvien toistovirheiden kompensoi-

miseksi. Säätö tehdään kaiuttimen takapaneelissa

olevien “Treble Tilt”-, “Bass Tilt”- ja “Bass Roll-Off”-

kytkimien avulla. Kaikki säädöt asetetaan tehtaalla

asentoon “OFF”, mikä antaa tasaisen taajuusvas-

teen kaiuttomassa tilassa. Säätöjen vaikutus toisto-

vasteeseen on esitetty kuvassa 4.

Suosittelemme akustisen mittausjärjestelmän

(esim. WinMLS) käyttöä kaiuttimien säätämisessä.

Ellei tällaista ole käytettävissä, säätö voidaan

tehdä myös korvakuulolta sopivia testiäänitteitä ja

-signaaleja hyväksikäyttäen. Taulukko 1 sisältää

muutamia suuntaa-antavia säätöesimerkkejä. Kai-

uttimien sijoitus ja akustinen ympäristö vaikuttaa

ratkaisevasti säätötarpeeseen, joten säätöön kan-

nattaa ryhtyä vasta kun kuuntelutilan järjestys on

saatu lopulliseen muotoonsa.

Treble Tilt

Treble Tilt-säätö (kytkin 1) vaimentaa kaiuttimen dis-

kanttitoistoa 5 kHz:n yläpuolella 2 dB, mitä voidaan

käyttää liian kirkkaalta tuntuvan toiston korjaami-

seen.

Volymkontroll

Ingångskänsligheten hos 8030A kan anpassas till

utsignalen på ansluten mixer, eller annan signal-

källa, genom att man justerar volymkontrollen på

högtalarens framsida.

Inställning av tonkontrollerna

Frekvensåtergivningen hos Genelec 8030A kan

anpassas till den akustiska miljö, som den ska an-

vändas i, med hjälp av tonomkopplarna på baksi-

despanelen.

Dessa kontroller är Treble Tilt, Bass Tilt och Bass

Roll-Off. Ett akustiskt mätsystem, som till exempel

WInMLS, rekommenderas för att analysera effek-

ten av de gjorda justeringarna, men en noggrann

lyssning, tillsammans med lämpliga testskivor, kan

ge goda resultat om inte ett testsystem ﬁnns till-

gängligt. Tabell 1 visar några typiska grundinställ-

ningar i olika lyssningssituationer. Bild 4 visar ef-

fekten av kontrollinställningarna i ett ekofritt rum.

Treble Tilt

Treble Tilt-kontrollen (switch 1) sänker diskantåtergiv-

ningen hos högtalaren vid frekvenser över 5 kHz med

2 dB. Detta kan användas för att mjuka upp återgiv-

ningen hos ett system som låter vasst i diskanten.

Bass Tilt

Bass Tilt-kontrollen erbjuder tre olika dämpnivåer

vid 2 kHz hos högtalaren, ofta nödvändigt när hög-

talaren placeras nära en vägg eller liknande. Dämp-

nivåerna är -2 dB (switch 3 ON), -4 dB (switch 4 ON)

och -6 dB (båda switcharna ON).
