| Content | As a part of APartʼs revolutionary series of convection cooled power amplifiers, Champ-4 is an amplifier without cooling fans. Its four discrete AB-class amplifiers deliver high quality musical sound, high dynamics, and high reliability - all in a one-unit 19” enclosure.
No fan
Power amplifiers have to operate in demanding circumstances. Places where the air is full of dust, nicotine or grease. Because power generates heat, power amplifiers typically have fans to keep their electronic circuits cool. Unfortunately, these cooling fans are a major headache in the use of high-power amplifiers. They tend to be noisy, and if -or rather, when- the fan breaks down because of dust collection, the amplifier overheats and ultimately fails. A fanless amplifier seems the logical thing, but -until now-, the idea never seemed to work for high quality amps with high output power. Thus, installers stick to fan-cooled models and get out of bed to replace a fried amplifier ….
Unique design
Especially for the CHAMP-series, APart introduces unique, custom-designed side mount heat sinks. In combination with a self-supporting low resonance frame, they make it possible to create a discrete power amplifier without a noisy and dust-collecting fan inside the enclosure. This means: less maintenance, no annual fan or dust filter exchange procedure, no more amplifier cleanout, and no more unwanted noise from cooling fans. Because of this, Champ-4 can rely on convection cooling only! Champ-4 has a torsion-free front in solid brushed aluminum. The removable brackets have a special fixation system that allows easy removal but still assures extraordinary-strength fixation. This makes it possible to use the unit rack mounted as well as freestanding. On the rear side of the unit the user will find solid binding posts and 4 sets banana screw plugs included.
APC power management circuitry gets the best out of an amplifier
APC power management circuitry has been designed especially for Champ series amplifiers. It is one of the most intelligent amplifier protection circuits ever designed, simply because it does the job without interfering with the typical dynamic character of music. APC allows the user to preset the power potential of the amplifier, while maintaining high power reserves and thus producing high, clean power. It constantly analyses incoming music signals and keeps dynamics alive. An additional ultra fast peak limiter avoids amplifier clipping. With APC, your system is always in control, including your speakers.
Bridging amplifiers and bridging channels
It is possible to bridge two channels of the Champ-4. By doing this you unite the power of two smaller amplifier channels into a more powerful amplifier channel. The resulting power is usually more than double the power of both amplifiers used individually with the same load. Check the user manual for instructions on how to proceed. Champ-4 is a four-channel amplifier. If you want to use a subwoofer, it is possible to bridge two of the channels for use as a subwoofer channel. The two remaining channels can be used for the top speakers.
It is the ideal solution to create a small music system for small dance floors or parties. As it is equipped with a X-over, you end up having a superior, yet easy-to-use sound system. The striking design and technical innovations of the Champ series are setting new industry standards….whether it is for AV, studio, gigs, home or catering applications: experience the pure musical power of CHAMP-4!

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. |
