SYSTEM

The Genelec 1038A is a three-way
active monitoring system including
loudspeaker drivers, speaker
enclosure, multiple power
amplifiers and active, low signal
level crossovers. Designed for
medium sized control rooms this
system is ideal for project studios,
film and video post-production
and broadcast monitoring. CD
mastering is also tailored for, where
broad bandwidth, high SPL's and
extended low frequency response
are essential. The 1038A is
designed to perform well both as
a free-standing monitor and flush
mounted into the control room wall.
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 2 m with program
signals. Versatile crossover
controls allow for precise matching
of the speaker system to different
acoustic conditions. The system
can be used both in 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 acts as quick release
hinges making maintenance
operations easy and
straightforward. The speaker
cabinet is constructed of veneered
MDF, which is heavily braced to
eliminate structural resonances.

AMPLIFIERS

The bass, midrange and treble
amplifiers each produce 400W,
120W and 120W, respectively of
short term power with very low
THD and IM distortion. Special
attention has been paid to
electronic design to ensure the
highest subjective sound quality
currently possible. The system
incorporates special circuitry for
drivers overload protection.
Thermal protection is also included
for the amplifiers.
