8030A Active Monitoring System
General description
The bi-amplified GENELEC 8030A is a two
way active monitoring loudspeaker designed
oration, and broad bandwidth.
The 8030A is ideal for near field monitor-
ing, mobile vans, broadcast and TV control
dios, multimedia applications and also for
use with computer soundcards. As an active
loudspeaker, it contains drivers, power ampli-
fiers, active crossover filters and protection
tion 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 fre-
ments. If necessary, the bass response of
the 8030A’s can be extended with a Genelec
7050A or 7060A subwoofer.
Positioning the loudspeaker
grated 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
(see Figure 1).
Connections
Before connecting up, ensure that the mains
switch is off and the volume control fully
counter-clockwise (see Figure 1). Do not con-
nect 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).
The male XLR “OUTPUT” connector can
be used for daisy-chaining up to six 8030A’s
together or for connecting a Genelec 7050A
uates 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 loudspeakers can
sole or other source by adjusting the volume
control on the front panel (see Figure 1).
Setting the tone controls
The frequency response of Genelec 8030A
can be adjusted to match the acoustic envi-
ronment by setting the tone control switches
on the rear panel. The controls are “treble
tilt”, “bass tilt” and “bass roll-off ”. An acous-
tic measuring system such as MLSSA or
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. 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 smoothening down an excessively
bright sounding system.
Bass tilt
Bass tilt offers three attenuation levels for the
sary 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
filtering at 85 Hz to complement the low-pass
filter on a Genelec 7050A subwoofer. This
switch should always be set to “ON” when
using the 8030A with 7050A subwoofers.
The factory setting for all tone controls is
“OF F” to give a flat anechoic response.
Alway s star t adjustment by setting all
switches to “OFF” position. Measure or listen
tions of settings to find the best frequency
balance.
Mounting considerations
Align the loudspeakers correctly
Always pl ace the l oudspeakers so t hat
their acoustic axes (see figure 1) are aimed
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
terline.
Minimise reflections
Acoustic reflections from objects close to the
loudspeakers like desks, cabinets, computer
tion blurring of the sound image. These can
be minimised by placing the loudspeaker
ting the loudspeakers on stands behind and
above the mixing console usually gives a
better result than placing them on the meter
bridge.
Minimum clearances
tioning 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
adjace nt to the amplif ier 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:
pler™) 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 witha a standard
microphone stand. On the rear there are two
M6x10 mm threaded holes for Omnimount®
size 20.5 brackets.
Maintenance
No user serviceable par ts 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
Alt hough the 803 0A has been designed
in accordanc e w ith i nter national safety
standard s, the fo ll ow in g warn in gs a nd
cautions should be obser ved to ensu re
speaker under safe operating conditions:
• Ser vi ci ng a nd a dj us tm en t must only
be pe r fo r med by q uali fie d s ervi ce
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 loud-
speaker or near it.
• This loudspeaker is capable of producing
sound pressure levels in excess of 85 dB,
which may cause perm anent hearing
damage.
• Free flow of air behind the loudspeaker is
necessary to maintain sufficient cooling.
Do not obstruct airflow around the loud-
speaker.
• 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.
