Lab.gruppen
– the company and the products
Lab.gruppen currently produce
eight power amplifier models of which
five utilize switch mode power supplies
(SMPS) and three utilize conventional
power supplies. These models range
2 ohms
from 2 150 W to 2 2400 W.
160 W
Whilst many competitors strive to
produce as many models as possible it
should be noted that since 1987 none of
our SMPS products have been "discon-
tinued". Products are often improved
allowing existing users to upgrade in
many cases.
An area of pride is safety compati-
bility – all of the products meet the
European safety approval IEC-65, and
the switch mode products meet the
European EMC rules. During the first
quarter of 1995 most products were
CE approved.
2 ohms
For installations in cinemas there are
320 W
two variants, which are THX approved.
Cooling system
Lab.Gruppen fan cooled amplifiers
utilize a special copper cooling system
called Intercooler
heat twice as good as aluminium).
Output devices (always bi-polar) are
mounted directly on a compact heat-
sink that produces turbulent airflow for
maximum heat dissipation. The airflow
in front of the heatsink is maintained by
a pressure chamber and two propor-
tional speed fans. A major advantage of
the Intercooler® is that there are only a
2 ohms
few degrees difference between all the
700 W
devices. Compare this to a conventional
cooling tunnel where there can be varian-
ces of up to 40 degrees between devices.
With such a difference, matching com-
plementary devices makes no sense!
Efficient cooling system with turbulent air flow.
Lab.Gruppen force cooled amplifiers
have front to rear cooling. The main rea-
son for this is because there is usually
cooler air outside the rack than inside or
behind (usually a closed rack with mini-
mal venting because of cables).
