High-tech in professional amplification!
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.
Key Features:
4 x 370 watts @ 8 ?
4 x 380 watts @ 4 ?
4 x 500 watts @ 2 ?
(Measured just below clip level, with all 4 channels driven)
Light weight and compact: only 8.6 kg (19lbs), 2U high
MLS? Switch: Lab.gruppen?s unique power matching for different loads
New Features:
Replaces the LAB 1200C
Easily accessible dust filters
Improved low-end power bandwidth
Extruded front panel for increased stability
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. | • Eight and four channel models with 300W and 150W per channel
