System
The bi-amplified GENELEC 1032A is a
two way active monitoring speaker
designed for high output, low coloration
and broad bandwidth. It is based on the
famous 1031A near field monitor but
offers extended low frequency output
with an increased maximum SPL.
Due to 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 and home studios. Designed as
an active speaker, this unit contains
drivers, power amplifiers, active
crossover filtering and protection
circuitry. The DCW Technology used
provides excellent frequency balance
even in difficult acoustic environments.
DriversDrivers
DriversDrivers
Drivers
The bass frequencies are reproduced
by a 10" (250 mm) bass driver loaded in
a 24 liters vented cabinet. The -3dB point
lies at 40 Hz and the low frequency
response extends down to 36 Hz (-6dB).
The high frequency driver is a 1" (25 mm)
metal dome with pure piston behavior up
to 23 kHz. The uniform dispersion control
is achieved with the revolutionary DCW
Technology pioneered by Genelec. This
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 dB/octave. The crossover
frequency is set to 1,8 kHz. By use of
active crossover controls ('treble tilt',
'bass tilt' and 'bass roll-off') this speaker
may be exactly matched to any
application.

Amplifiers
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 180 W
and 120 W, respectively, of short term
power. The fast, low distortion amplifiers
are capable of driving the stereo system
to peak output levels in excess of 124 dB
SPL at 1 m. The unit incorporates a
special protection circuitry for driver
overload protection and amplifier thermal
overload protection. Variable input
sensitivity allows for accurate level
matching to the mixing console.

2. Installation
Each 1032A monitor is supplied with an
integrated amplifier unit, a mains cable
and an operating manual. Once
unpacked, place the loudspeaker in 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). Check
that the mains voltage selector is correctly
set. Audio input is made via a 10k Ohm

dimensions in horizontal and vertical
mounting positions.

Setting the input sensitivitySetting the input sensitivity
Setting the input sensitivity
Adjustment of the input sensitivity of each
speaker can be made to match that of
the mixing desk or other source, by use
of the input sensitivity control on the rear
panel (see figure 4). A small screw driver
is needed for the adjustment. The
manufacturer default setting for this
control is -6 dBu (fully CW) which gives
SPL of 100 dB @1m at -6 dBu input level.
Note that to get the full output level of 113
dB SPL, an input level of +7 dBu is
needed at this setting.

The acoustic 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 manufacturers default
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
balanced (XLR), but unbalanced leads
may be used as long as pin 3 is grounded
to pin 1 of the XLR (see figure 3).
Once connection has been made, the
speakers are ready to be powered-up.

'OFF' position. Then set only one switch
to ON position to select response curve
needed. If more than one switch is set to
'ON' (within one switch group) the
attenuation value is not accurate.
Vertical / horizontal mountingVertical / horizontal mounting
Vertical / horizontal mountingVertical / horizontal mounting
Vertical / horizontal mounting
The speakers are delivered normally for
vertical mounting. If horizontal mounting
is needed the DCW plate can 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 and the gasket. Rotate
the plate 90 degrees to the appropriate
direction and remount the screws. Note
that to get mirror image pair the DCW
must be rotated to different direction in
left and right speaker. In horizontal
mounting position the bass drivers should
point inwards to get better low frequency
summing.
Console top mountingConsole top mounting
Console top mountingConsole top mounting
Console top mounting
If the 1032A's are used for console top
monitoring it is recommended not to
mount the speakers directly on the
console. Instead position the speakers
slightly behind the console by using
floor stand or wall mount at the console
back side. This prevents the reflection
from the console surface from coloring
the sound.
Overload indicatorsOverload indicators
Overload indicatorsOverload indicators
Overload indicators
The speaker is provided with two warning
LED's marked 'OVL' and 'ON'. The green
ON-LED when lit indicates that the
speaker is ready for use. The red OVL-
LED indicates that the amplifier is
overloaded or the driver protection circuit
is activated. In both cases reduce the
signal level so that the LED stops blinking.
If the OVL-LED stays on constantly it
indicates that the amplifier thermal
protection is activated. Let the amplifier
cool down and check that the ventilation
at the rear side of the speaker is not
blocked. There should be a clearance of
more than 4" (10cm) between speaker
rear and any solid surface at the back.
