SYSTEM
The Genelec 1032A is a two-way
active monitoring system including
magnetically shielded loudspeaker
drivers, speaker enclosure, multiple power amplifiers and active,
low signal level crossover. Based
on the famous 1031A near field
monitor, the 1032A offers extended
low frequency response and an
increased maximum SPL. Due to
it's compact size, this system is
ideal for high power near field monitoring. Furthermore, it is well suited
to general purpose broadcasting
applications, TV control rooms,
mobile vans and CD mastering as
well as home studios.
The unique Directivity Control
Waveguide (DCW) Technology
used provides excellent stereo imaging and frequency balance even
in difficult acoustic environments.
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 with
program signals.
Versatile crossover controls allow
for precise matching of the speaker
system to different acoustic conditions. The system can be used in
both vertical and horizontal orientation by simply rotating the DCW
unit.
INTEGRATED CONSTRUCTION
The system is very easy to use as
only mains power and input signal
are needed. Uniform performance
is obtained through the integration
of the loudspeakers and amplifiers
as a complete matched and calibrated package. The rugged amplifier is mounted into the enclosure
with vibration isolators which also
act as quick release hinges making
maintenance operations very easy
and straightforward. The speaker
cabinet is constructed of veneered
MDF, which is heavily braced to
eliminate structural resonances.

AMPLIFIERS
The bass and treble amplifiers each
produce 180 W and 120 W respectively of short term power with very
low THD and IM distortion. Special
attention has been paid to the electronic design to ensure the highest
subjective sound quality currently
possible. The system incorporates
special circuitry for driver overload
protection. Thermal protection is
included for the amplifiers.

bass and tweeter drivers.
CROSSOVER FILTERS
The crossover frequency of the
active crossover is 1.8 kHz. In
order to obtain uniform frequency
balance in differing acoustic conditions, special calibrated controls
are included in the crossover. Three
such controls are at the users disposition including treble and bass
tilt, and bass roll-off switch. Each of
these controls allow for adjustment
in 2 dB increments and also provide the possibility of muting the
channel for test purposes. A high
pass filter is included in the LF
channel to protect the woofer from
subsonic signals. The crossover
network is driven by an active balanced input stage. Variable input
sensitivity allows for accurate level
matching to the mixing console.
The upper curve group shows the horizontal directivity characteristics
of the 1032A in its vertical configuration measured at 1 m. The lower
curve is a 1/3 octave band power response, measured in an IEC
approved reverberation chamber.
DRIVERS
The bass frequencies are repro-
duced by a 250 mm (10") bass
driver loaded by a 24 litre vented
box. The -3 dB point is 40 Hz and
the low frequency response extends down to 36 Hz.
The high frequency driver is a 25
mm (1") metal dome, with pistonic
behavior upto 23 kHz, is loaded by
a proprietary DCW. Both drivers
are magnetically shielded for applications where the stray magnetic
field must be minimized.
DCW TECHNOLOGY
The revolutionary Directivity Con-
trol Waveguide Technology is a
means of greatly improving the
performance of a direct radiating
multiway loudspeaker under normal listening conditions. The basic
idea is to match the different drive
units precisely, in terms of both
frequency response and directivity. This will result in a smoother
and virtually uncoloured off-axis
system response. Also, due to improved directivity control, especially
in the midrange frequencies, more
direct sound and less early boundary reflections are received at the
listening position. This gives improved stereo imaging and ensures
the system is less sensitive to differing control room acoustics than
any conventional direct radiator design. The DCW Technology improves the drive unit sensitivity by
Calibrated 'Tilt'
switch. MUTE

+2 to +6 dB thus increasing the
system maximum sound pressure
level.
The tweeter driver is mounted in a
DCW to match the dispersion
characteristics to that of the bass
driver. The DCW may be rotated
for horizontal or vertical mounting.
The upper curves show the effect of the 'bass tilt' control on the free
field response. The lower curves show the effect of the 'treble tilt' and
'bass roll-off' controls.
