System
The bi-amplified GENELEC 1030A is a
two way active monitoring speaker
designed to be small but still have high
output, low coloration and broad
bandwidth. It shares many design
features with the famous 1031A near
field monitor.
Due to its compact size, integrated
construction, excellent dispersion and
precise stereo imaging, this speaker
system is ideal for Near Field
monitoring, mobile vans, broadcast and
TV control rooms, surround sound
systems and budget and home studios.
Designed as an active speaker, this
unit contains drivers, power amplifiers,
active crossover filters and protection
circuitry. The Directivity Control
Waveguide (DCW) technology used
provides excellent frequency balance
even in difficult acoustic environments.
DriversDrivers
DriversDrivers
Drivers
The bass frequencies are reproduced
by a 170 mm (6 1/2") bass driver loaded
in a 6.5 liter vented cabinet. The -3 dB
point lies at 52 Hz and the frequency
response extends down to 47 Hz
(-6 dB).
The high frequency driver is a 19 mm
(3/4") metal dome. Uniform dispersion
control is achieved with the
revolutionary DCW Technology
pioneered by Genelec, which has also
resulted in perfect phase and delay
uniformity at the crossover frequency.
Both drivers are magnetically shielded.
CrossoverCrossover
CrossoverCrossover
Crossover
The active crossover network consists
of two parallel bandpass filters.
Acoustically, the filters are
complementary and the slopes are
24 - 32 dB/octave. The crossover
frequency is 3.5 kHz. The active
crossover controls ('treble tilt', 'bass
tilt' and 'bass roll-off') allow this speaker
to be exactly matched to any
application.

The amplifier unit is mounted to the
rear of the speaker enclosure on quick
release vibration isolators, to ensure
rattle free operation and long term
reliability. The bass and treble amplifier
produce 80 W and 50 W of short term
its required listening position, taking
note of the line of the listening axis (see
figure 2). Before connecting up, ensure
that the mains switch is off (see figure 4)
and the mains voltage selector is
correctly set. 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 connection
has been made, the speakers are ready
to be switched on.

Setting the input sensitivitySetting the input sensitivity
Setting the input sensitivity
The input sensitivity of the speakers
can be matched to the output of the
mixing desk, or other source, by
adjusting the input sensitivity control
on the rear panel (see figure 4). A small
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.
Setting tone controlsSetting tone controls

The response of the system may also
have to be adjusted to match the
acoustic environment. The adjustment
is done by setting the three tone control
switches 'treble tilt', 'bass tilt' and 'bass
roll-off' on the rear panel of the amplifier.
The manufacturer's settings for these
controls are 'All Off' to give a flat
anechoic response. See Figure 1 for
suggested tone control settings in
differing acoustic environments. Figure
5 shows the effect of the controls on the
anechoic response. Always start
adjustment by setting all switches to
'OFF' position. Then set only one switch
to the ON position to select the response
curve needed. If more than one switch
is set to 'ON' (within one switch group)
the attenuation value is not accurate.

power respectively. The fast, low
distortion amplifiers are capable of
driving a stereo pair to peak output
sound pressure levels in excess of 115
dB at 1 m. The unit incorporates special
circuitry for driver overload protection.
Variable input sensitivity allows for
accurate level matching to the mixing
console.

Vertical / horizontal mounting
The speakers are normally delivered
set up for vertical mounting. If horizontal
mounting is needed the DCW plate
may be rotated so that the GENELEC
logo is located at the bottom left corner
of the DCW. Remove the four corner
screws of the DCW (use a Torx 20
screw driver) and pull the plate carefully
out without stressing the wires or the
gasket. Rotate the plate 90 degrees in
the appropriate direction and remount
the screws. Note that to get a mirror
image pair, the DCWs must be rotated
in different directions for the left and
right speakers. When used in the
horizontal position, the bass drivers
should be on the inside to provide
better low frequency summing.

Console top mounting
If the 1030A's are used for console top
monitoring, avoid mounting the
speakers directly on the console.
Instead position the speakers slightly
behind the console by using floor
stands or wall mounts. This prevents
the reflection from the console surface
from coloring the sound.

Although the 1030A has been designed
in accordance with international safety
standards, to ensure safe operation
and to maintain the instrument under
safe operating conditions, the following
warnings and cautions must be
observed:
•Servicing and adjustment must
only be performed by qualified service
personnel.
•The amplifier's rear panel must not
be opened, except by persons who
are aware of the hazards involved.
•Do not use this product with an
unearthed mains cable as this may
lead to personal injury.
