Main Monitor For Large
Control Rooms

SYSTEM

The Genelec 1035B is an ex­tremely powerful monitor system,
designed for large control rooms.
It consists of a 600 liters (21 cu.
ft.) speaker enclosure and a 19"
electronics rack, which contains
active crossovers, three channel
power amplifiers and sophisti­cated protection and diagnostic
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 136 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 ex­cellent 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 Audio Processing Unit (APU)
which contains the crossover,
also contains diagnostic and pro­tection circuits. These monitor the
amplifier channels for each driver
and will automatically reduce the
monitor's input gain, to protect a
driver from overload and distor­tion. Reducing the gain of the
entire monitor, rather than just that

of the overloaded channel, pre­serves its frequency balance. The
protection circuitry also guards
against DC, shorting and exces­sive temperature, and will take ap­propriate action to prevent dam­age. LED displays show the
system's condition in detail on the
APU front panel and in summarized
form on the loudspeaker enclosure.

AMPLIFIERS

The bass, midrange and treble
amplifiers produce 2 x 1100, 1 x
600 and 1 x 300 watts 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 5 m,
10 core cable is supplied for the
speaker connection. Longer
lengths are available on applica­tion.

DRIVERS

Bass frequencies are repro­duced by two long throw 385 mm
(15") woofers in a vented, dual
chamber configuration giving a
frequency response extending
down to 20 Hz, with the -3 dB
point at 29 Hz.

The mid range frequencies are
reproduced by two 130 mm (5")
high sensitivity direct radiating
cone drivers and the high fre­quency driver is a 25 mm (1")
throat compression driver, with
an upper -3 dB point at 22 kHz.
