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.
