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).

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

from 23150 W to 232400 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.

For installations in cinemas there are

two variants, which are THX approved.

Cooling system

Lab.Gruppen fan cooled amplifiers

utilize a special copper cooling system

called Intercooler

(copper conducts

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

few degrees difference between all the

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!
