Three 120 W amplifiers are housed in the speaker cabinet
Horizontal version S30C H
Vertical version S30C V
AMPLIFIERS
The bass, midrange and treble
amplifiers each produce 120 W of
short term power with very low
THD and IM distortion. Special
attention is paid to electronics
design to get also the subjective
sound quality as good as cur-
rently possible. To improve
acoustic transient response the
output impedance of the woofer
amplifier is made negative. The
system incorporates a special
circuitry for protecting drivers
from overload. Thermal protection
is included for the amplifiers.
SYSTEM
The Genelec S30C is a three-way
Active Monitoring System includ-
ing loudspeaker drivers, speaker
enclosure, multiple power amplifi-
ers and active, low level cross-
overs. All these are housed en-
tirely within the speaker cabinet.
Featuring a proprietary ribbon
tweeter the S30C is a no compro-
mise design. The fast, low distor-
tion amplifiers are capable of
driving a stereo system to peak
output levels in excess of 122 dB
SPL at 1 m with program signals.
Versatile crossover controls allow
for precise matching of the
speaker system to different
acoustic conditions. Designed for
relatively small control rooms and
available in vertical and horizontal
versions, this system is ideal for
general purpose broadcasting
and television studios, digital
workstations, post production
facilities and mobile recording
vehicles. The high output and
INTEGRATED CONSTRUCTION
The system is very easy to use
as only mains power and input
signal are needed. The perfor-
mance is consistent because the
loudspeakers and amplifiers are
built as a single integrated,
matched and calibrated package.
The rugged amplifier is mounted
into the enclosure with vibration
isolators which act also as quick
release hinges making possible
maintenance operations very
easy and straightforward. The
speaker cabinet is constructed of
veneered MDF, which is heavily
braced to eliminate structural
resonances.

CROSSOVER FILTERS
The crossover frequencies of the
active crossover network are 420
Hz and 4 kHz. In order to reach
uniform frequency balance in
different acoustic conditions,
special calibrated controls are
included in the crossover. The
Bass, Midrange and Treble level
controls operate in 1 dB steps.
Moreover, the low frequency Tilt-
and Roll-off controls both have
four 2 dB steps to allow refined
LF response tailoring. A high-
pass filter is included in the LF
channel to protect the woofer
from subsonic signals. The
crossover network is driven by an
active balanced input stage.
Variable input sensitivity allows
for accurate level matching to the
mixing console.
DRIVERS
The 210 mm ( 8") woofer is
loaded with a 24 liters (0.85
cu.ft.) vented box. The woofer
has a very large magnet and a
long linear excursion capability
(±9 mm, ±0.35"). Both features
are needed to reach low frequen-
cies with reasonable efficiency
and high acoustic output (SPL) in
a small enclosure. The -3dB point
is 42 Hz and the low frequency
response extends down to 35 Hz.
A carefully designed 80 mm cone
driver, sealed in a cast aluminum
alloy housing, reproduces the
critical midrange where the ear is
most sensitive. To minimize
coloration the diaphgram is spe-
cially impregnated. As a result,
the midrange driver’s response
actually extends well beyond the
range required by the crossovers.
The high frequency driver is a
proprietary ribbon tweeter with a
moving mass of only 32 mg and
frequency response extending
into ultrasonic range. The disper-
sion characteristics of both
tweeter and midrange driver are
matched for uniform tonal bal-
ance in different rooms. A mag-
netic shielding option is available
for applications where magnetic
stray field must be minimized.
The unique ribbon tweeter and
the sealed midrange driver are
mounted on a separate chassis
to match the dispersion charac-
teristics.

The upper curve group shows the horizontal directivity characteristics
of S30C in its vertical configuration measured at 1 m. The lower curve
is a 1/3 octave band power response, measured in an IEC approved

The curves above left show the effect of the 'bass tilt', 'bass level' and
'bass roll-off' controls on the free field response. The curves to the
right show the effect of the treble and midrange 'level' controls.
