The Genelec 1038BC is a dedicated center
channel for three channels (LCR) and mul-
tichannel surround systems. Its slim and
compact cabinet has been designed for opti-
mum placement in the limited space above or
below video monitors or screens.
As its name suggests, the Genelec 1038BC
is best suited for use as a center channel
speaker with a pair of Genelec 1038B active
monitors. The 1038BC employs the same
midrange, treble drivers and Directivity Con-
trol Waveguide™ (DCW™) as a standard
1038B, as well as the same amplifi er unit to
ensure complete tonal compatibility.
Genelec 1038BC is a three-way active
monitoring system including magnetically
shielded loudspeaker drivers, speaker enclo-
sure, multiple power amplifi ers and low level
active crossovers. Designed for medium
sized control rooms this system is ideal
for video and fi lm post-production studios,
multichannel music recording and broadcast
main monitoring. DVD mastering is also well
tailored for where broad bandwidth, high
SPL’s and extended low frequency response
are essential.
The separate amplifi er unit is built into
a rack mount chassis for easy fi tting into a
standard 19” equipment rack. A standard
10 meter connecting cable is provided to go
between the amplifi er unit and the speaker
enclosure. It is recommended to fl ush mount
the 1038BC monitor into the control room
wall, but it can also be used as a free-stand-
ing monitor.
The unique Directivity Control Waveguide
Technology developed by Genelec provides
excellent stereo imaging and frequency bal-
ance even in diffi cult acoustic environments.
The fast, low distortion amplifi ers are capable
of driving a 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 orientations by simply rotating the
DCW unit.
Integrated construction
Uniform performance is obtained through the
integration of loudspeakers and amplifi ers as
a complete matched and calibrated package.
The rugged amplifi er unit is mounted into
a rack mount chassis with vibration isola-
tors which also act as quick release hinges
making maintenance operations easy and
straightforward. The speaker cabinet is con-
structed of veneered MDF which is heavily
braced to eliminate structural resonances.
Amplifi ers
The bass, midrange and treble amplifi ers
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. To improve the acoustic transient
response the output impedance of the woofer
amplifi er is made negative. The system incor-
porates special circuitry for drivers overload
protection. Thermal protection is included for
the amplifi ers.
Drivers
The bass frequencies are reproduced by two
250 mm (10”) bass drivers loaded with a 110
liters vented box. The -3dB point is 33 Hz and
the low frequency response extends down to
29 Hz (-6 dB). The midrange frequencies are
reproduced by a proprietary 130 mm (5”)
direct radiating cone driver loaded with the
DCW. The high frequency driver is a 25 mm
(1”) metal dome also loaded by the DCW.
All drivers of the 1038BC are magnetically
shielded in order to minimize interference
with video monitors and stray magnetic fi eld.
DCW technology
The revolutionary Directivity Control Wave-
guide Technology is a means of improving the
performance of a direct radiating multi-way
loudspeaker in normal listening conditions.
The basic idea is to match the different drive
units precisely, both in terms of frequency
response and directivity. This will result
in a smoother and a virtually uncoloured
off-axis response of the system. Due to
improved control of the directivity, especially
