The fP 2200 is a lightweight and space-saving power amplifier, ideal for use
in high quality touring sound systems as well as in demanding permanent
installations.
The latest semiconductor technology is utilized in the new ferrite Power (fP) amplifiers.
This, together with Lab.gruppen’s proprietary copper cooling system, Intercooler®,
enhances the 2 ohms capability. Two easily accessible dust filters on the front ensure a
clean front-to-rear airflow.
A new Bi-phase wiring scheme also increases the capacity of the switch mode power
supply. This extends the power bandwidth in the low end.
Besides the traditionally superb Lab.gruppen sonic performance, there is a full line of
features to make the fP family functional in all situations from installation to high perfor-
mance live sound systems:
Regulated switch mode power supply
Today there are many lightweight, switch-mode amplifiers in the market. However, the
unique Lab.gruppen switch mode power supply technology offers a number of essential
advantages that make it superior to other seemingly similar power supply designs.
The most important features are the regulated power supply and the extreme power
efficiency. The regulated power supply easily deals with a very high variation in the AC
mains voltage: it can drop by up to 20% below its nominal level - e.g. to 180 V (90V)
instead of 230 V (115V) - without any problem. Perhaps even greater benefits result from
the extreme efficiency of Lab.gruppen amplifiers: only a fraction of the energy from the
AC mains is turned into heat.
A regulated power supply also presents some other sonic advantages, such as better
cone control and the same fast response as a conventional power supply
Multiple positions Gain switch
To meet the demands for a flexible gain structure in the system, Lab.gruppen offers a
multiple position gain DIP switch. The maximum amplifier gain can be set to all industry
standards: 20, 23, 26, 29, 32, 35, 38 and 41 dB.
Sophisticated protection circuitry, combining:
– ALS™ short circuit protection; the Adaptive Limiting System permits very high peak
currents, but keeps the amplifier within the Safe Operation Area.
– DC protection; protects against infrasonic signals.
– VHF protection; protects the loudspeakers against strong very high frequency non-
musical signals above the audible range.
– Thermal protection; prevents the amplifier from being overheated. The protection
indicators on the front panel are switched on, as a warning, before the protection
process is initiated.
– AC protection; shuts down the power supply if the line voltage is outside the
operating voltage.
– Clip limiter; prevents severely clipped waveforms from reaching the loudspeakers,
whilst maintaining full peak power.
