System
The Genelec 1238CF is a compact three-
way DSP monitoring loudspeaker includ-
ing drivers, multiple power amplifiers and
digital signal processing (DSP) circuitry.
The 1238CF is compatible with proprietary
Genelec Loudspeaker Manager™ (GLM™)
control software and can be combined with
Genelec 8200/7200 Series products in the
same control network. The 1038CF is opti-
mized for systems utilizing one or multiple
subwoofers in medium sized control rooms
and suited for music recording studios, film
and video post-production and general
broadcasting monitoring as well as for mas-
tering suites.
The 1238CF is designed to perform well
both as a free-standing monitor and flush
mounted into the control room wall. When
flush mounting the loudspeaker, the space
behind the loudspeaker enclosure must be
sufficiently ventilated in order to dissipate
heat generated by the amplifier unit located
at the back panel of the loudspeaker.
The Directivity Control Waveguide™
(DCW™) Technology developed by Genelec
provides excellent stereo imaging and fre-
quency balance even in difficult acoustic en-
vironments. Versatile crossover controls al-
low for precise matching of the loudspeaker
system to different acoustic conditions.
The rugged amplifier unit is mounted into
the enclosure with vibration isolators which
also act as quick release hinges making
maintenance operations very easy and
straightforward. The loudspeaker cabinet
is constructed of painted MDF, which is
heavily braced to eliminate structural reso-
nances.

Digital Signal Processing

Genelec 1238CF and 8200 and 7200 Series
loudspeakers and subwoofers feature an
independent dedicated digital signal process-
ing engine in each loudspeaker. All AES/EBU
digital audio formats are supported, as well
as standard line level analog signals. The
system accepts sampling rates ranging from
32 kHz to 192 kHz.
Up to 30 loudspeakers and subwoofers
can be connected on, set up, and controlled
with GLM™ control network over standard
CAT5 cabling. Genelec Loudspeaker Man-
ager™ (GLM™) is a computer software pro-
viding full real-time control of all aspects of all
loudspeakers on the network.

DSP Monitoring System
Fast and Easy Calibration
With AutoCal™
AutoCal™ is a fully automated loudspeaker
system alignment algorithm within GLM™
software. It sets levels, distance compen-
sating delays, phase (for subwoofers) and
room response equalization using a factory-
calibrated Genelec measurement micro-
phone included in the GLM™ software kit.
SinglePoint™ and MultiPoint™ microphone
locations for one, two, or three-person mixing
environments can be selected. The Interac-
tive Response Editor provides visual readout
of measured and corrected response curves
as well as full manual editing of all acoustical
settings.
All functions and settings are stored in
GLM™ System Setup Files or directly into
each loudspeaker. As the control network
is separate from the audio cabling, the con-
trol network can be dismantled and moved
to another place after saving the settings
into the loudspeakers. Furthermore, the
1238CF retains features similar to analog
8000 series active loudspeakers and can
be used independently of the GLM™ con-
trol network.
