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.

  The S Series of RAM Audio amplifiers distils all these features to fulfill all your needs, whether youʼre starting a P.A. amplifier project from scratch, or you need to upgrade your present sound reinforcement equipment. In the S Series amps, you'll find five 2-channel models and five 4-channel models, all offering plentiful power levels at low distortion in the range of 1.5 to 6 kilowatts, yet weighing in around 8 kilos and 30 cm deep. • Ultra-compact and lightweight 2-U high • Laser cut aluminum front panels with integrated carrying handles • Neutrik® XLR input connectors, input and signal link in 2 channel models • Input Link switch: allow daisy-chaining of the input signal • Neutrik® Speakon® output connectors • Detented sealed potentiometers for easy recall of volume settings • ICL™, PMS™, Hi-temp, Signal indicators per channel • Power on and Stand-by leds • Highly versatile with multiple configuration and additional module options • Full PC control via EtheRAM (with EtheRAM Control module) • Switchable ICL™ clip-limiters per channel • Switchable (30-50 Hz) sub-sonic highpass filter per channel • Three-position gain selector (26, 32 or 38 dB) • Dual or bridge mode selector • Twin temperature controlled, back to front cooling fans • Oversized power components (high SOA reserve specification) Standard Signal Inputs Module: The S Series amps are equipped as standard with twin Neutrik® XLR, doubled by two other XLR connectors for linking purposes. In the 4 Channel models an XLR input per channel is provided with the signal linking facility. Analog Processor Module: permits a very easy, user-friendly signal processing to enable the amp to set up a bi-amp system without any other outboard device. These are the Processor's main characteristics: • 2-way stereo crossover (dual mono or single bridged sub output) • 24dB/oct Linkwitz-Riley configurable crossover (90, 100 o 120Hz) • Adjustable attenuation in the High-pass outputs (-3, -6 or -9dB) • Adjustable Limiter, relative to Max. Output (-3, -6 or -9dB) DSP44_S Module: Digital Signal Processor fully programmable through an USB port. These are the Processor's main characteristics: • 4 Inputs/4 Outputs or 2 In/2 Out free route configurable. • 24 bits/192 kHz 256x Oversampling Converters. • Output Delay: 0 to 7.1 meters (20.69ms) per channel. • XOver: Up to 48dB/oct Butterworth, Linkwitz-Riley and Bessel. • EQ: 9 filters per channel (Parametric, Shelving, LP,HP,BP,SB). • Gain, Mute and Phase inversion per channel. • RMS Power and Peak Voltage output limiter per channel. • Real Time operation from USB or front panel configuration.
