SYSTEM

The Genelec 1039A is a very pow­erful monitor system, designed
for large control rooms. It consists
of a 320 litres speaker enclosure
and a 7U 19" equipment rack which
contains active crossovers, three
channel power amplifiers and
driver protection circuitry. The
speakers are designed for flush
mounting in the control room wall,
although they may be used free
standing and can produce peak
sound pressure levels in excess
of 126 dB.

Bass, midrange and treble con­trols are included to allow the
speakers to be matched to the
acoustic conditions in different
control rooms. The sensitivity of
the system to its environment is
minimized by the unique Directiv­ity Control Waveguide (DCW)
Technology, which provides ex-

cellent stereo imaging and fre­quency balance even in difficult
acoustic situations. The system
can be used in both vertical and
horizontal orientations by simply
rotating the DCW unit.

PROTECTION CIRCUITRY

The 1039A amplifier unit contains
electronic circuitry which serves
to protect the drivers from dam­age by overload and distortion.
These circuits monitor each am­plifier channel and automatically
reduce the signal level to the driver
if an overload condition occurs. In
addition the signal levels to all of
the drivers in the monitor are re­duced by the same amount. This
preserves the frequency balance
of the monitor. A LED located on
the loudspeaker enclosure indi­cates the condition of this protec­tion circuitry.

AMPLIFIERS

The rack mounting amplifiers including crossover and protection.

The bass, midrange and treble
amplifiers each produce 2 x 400W,
350W and 120W of short term
power, respectively, with very low
harmonic and inter-modulation
distortion. The electronics have
been carefully designed to en­sure the highest subjective sound
quality currently possible. Ther­mal protection is provided for the
amplifiers. A standard 10 m cable
is supplied for the speaker con­nection. Longer lengths are avail­able upon special order.

DRIVERS

Bass frequencies are reproduced
by two long throw 385 mm (15")
woofers in a vented configuration
giving a frequency response ex­tending down to 25 Hz, with the ­3 dB point at 29 Hz.
The midrange frequencies are
reproduced by a 130 mm (5") high
sensitivity direct radiating cone
driver and the high frequency
driver is a 25 mm (1") metal dome
unit, with an upper -3 dB point at
22 kHz. The mid and high fre­quency drivers have field replace­able diaphragms and are mounted
in a DCW for optimized directivity
control.

The active crossover network con­sists of three parallel band pass
filters, with crossover frequencies
at 400 Hz and 3.2 kHz, and a
common balanced input stage.
All the filters are aligned for equal
phase and group delay charac­teristics and are acoustically
complementary. The filter slopes
are 24 dB/octave.
To adjust the balance of the driv­ers to suit a particular acoustic
environment, bass midrange and
treble level controls are included,
which adjust the output in 1 dB
steps. In addition, low frequency
roll-off and 'tilt' controls are present,
to allow further refinement of the
system response.

SOFFIT MOUNTING

Soffit (flush) mounting of a loud­speaker removes problems
caused by diffraction effects and
reflections from the wall behind it.
Diffraction of sound at the loud­speaker cabinet edges degrades
the transient response and direc­tional properties, while reflections
will cause interference, potentially
leading to large dips in the low
frequency response. The use of
DCW Technology removes the
diffraction effects to a large ex­tent. Moreover, the 1039A has
versatile frequency response
controls to compensate for varia­tions due to different speaker
positioning and room loading. This
allows it to be either soffit mounted
or to be used as a free standing
unit without using external equal­ization, although soffit mounting is
highly recommended.

DCW TECHNOLOGY

The revolutionary Directivity Con­trol Waveguide Technology is a
means of greatly improving the
performance of a direct radiating
multiway loudspeaker under nor­mal listening conditions. One of
the basic ideas is to match the
performance of the drivers in
terms of both frequency response
and directivity. This results in
smoother frequency response
both on and off axis. Also, due to
improved directivity control, es­pecially in the midrange frequen­cies, more direct sound and less
reflected sound is 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 sen-

sitivity by +2 to +6 dB thus in­creasing the system maximum
sound pressure level.

The high and mid frequency
drivers are mounted in a DCW
to match their dispersion
characteristics. The DCW may
be rotated for horizontal or
vertical mounting.
