The fP 2400Q is a lightweight and space-saving four-channel
power amplifier, ideal for use in high quality touring sound
systems as well as in demanding permanent installations. The fP
2400Q offers a diverse choice of applications, such as:
multi-channel monitor systems, four-channel reproduction, and
compact amplification in active 2-, 3-, and 4-way systems.
The fP 2400Q makes possibile the bridge connection of one or
two of the two pairs of channels (channel A and B and/or channel
C and D). It also features Lab.gruppen’s unique power
matching solution, the MLS switch, which offers endless
combinations for solving most of the problems related to varying
impedances and maximum power capacities of loudspeakers. 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 capacity.
Two easily accessible dust filters on the front ensure a clean
front-to-rear airflow. Additionally, 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
performance 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 and 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 instead of
230 V – 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.
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.
