System
The Genelec 8020C is a very compact bi-
amplified active monitor system with perfor-
mance comparable to much larger systems.
The 8020C excels in applications where space
is at a premium, taking full advantage of the
unconventional design and advanced technol-
ogies of Genelec's 8000 Series loudspeaker
range. The all-aluminium Minimum Diffrac-
tion Enclosure™ (MDE™) and advanced
Directivity Control Waveguide™ (DCW™)
technologies are carefully matched with com-
plementing advanced amplifier and electronics
circuitry and the latest drivers. Bass response
reaches down to 65 Hz (-3 dB) with low dis-
tortion due to a uniquely new rear reflex port
design. The system's excellent directivity char-
acteristics and accurate imaging together with
its compact size and flexible mounting options
make the 8020C the perfect monitoring tool for
a wide range of applications.
The 8020C has been specially designed
to have a sufficient LF extension for a variety
of situations. However if greater SPL's and
a lower cutoff frequency are required, it can
be complemented with Genelec 7050B sub-
woofer, which has a lower cutoff point of 25 Hz.
Integrated construction
The 8020C is very easy to set up and use,
the only connections required are the mains
supply and the line level input. The input is
made via a balanced female XLR connector.
The volume control is located on the front
panel. This allows easy level matching with
other audio equipment.
The integrated design allows the amplifiers
and the drivers to be calibrated as a single
unit, eliminating the effects of component tol-
erances and ensuring consistent quality.
Crossover filters
The amplifier unit contains an active cross-
over, a feature more commonly used in large
and expensive control room monitors. This is
the ideal method for dividing the input signal
between the driver units. The active crossover
allows the overall response of the system to
be optimized to an extent impossible with a
passive system.
To maintain uniform frequency balance
in differing acoustic environments, special
calibrated controls are included in the active
crossover network. These controls include
"treble tilt", "bass tilt" and "bass roll-off"
switches.
Amplifiers
The bass and treble amplifiers produce
20 W of output power each, with very low
THD and IM distortion values. The amplifiers
are designed to ensure the highest subjec-
tive sound quality currently possible. The
amplifier unit also contains a protection cir-

Active Monitoring System
cuit that monitors the output levels and pre-
vents any damage to the drivers. This makes
the system immune to overloads and spuri-
ous signals.
Drivers
A 19 mm ( / ") metal dome tweeter is loaded

by an advanced DCW™ waveguide. The
DCW™ is integrated into the one piece front
baffle.
The 105 mm (4") bass cone driver is
mounted in a newly designed bass reflex
enclosure. The long, flow optimized reflex
tube has a large cross sectional area and
terminates with a wide flare at the back of
the enclosure.
Protective grilles are positioned in front of
both drivers. Magnetic shielding is standard
on the 8020C. Shielding is vital for applica-
tions such as video post production, where
stray magnetic fields must be minimized.
ISS autostart function
TM
When the power switch on the back panel of
the loudspeaker is set to "ON", the Intelligent
Signal Sensing (ISS ) autostart function
TM TM
of the 8020C is active. Automatic power-
ing down to standby mode happens after a
certain time when playback has ended. The
power consumption in standby mode is typi-
cally less than 0.5 watts. The playback will
automatically resume once an input signal is
