System

The Genelec 8020B is a very compact bi-

amplified active monitor system with perfor-

mance comparable to much larger systems.

The 8020B 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 Diffraction

Enclosure™ (MDE™) and advanced Directiv-

ity Control Waveguide™ (DCW™) technolo-

gies are carefully matched with complementing

advanced amplifier and electronics circuitry

and the latest drivers. Bass response reaches

down to 65 Hz (-3 dB) with low distortion due

to a uniquely new rear reflex port design. The

system's excellent directivity characteristics

and accurate imaging together with its com-

pact size and flexible mounting options make

the 8020B the perfect monitoring tool for a

wide range of applications.

The 8020B 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 subwoofer,

which has a lower cutoff point of 25 Hz.

Integrated construction

The 8020B 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-

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 (3/4") 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 8020B. Shielding is vital for applica-

tions such as video post production, where

stray magnetic fields must be minimized.
