LAB.Gruppen PLM 20000Q Used, Second hand

Ref. code: 1.07.144

PLM 20000Q

The PLM 20000Q Powered Loudspeaker Management system seamlessly integrates an extraordinarily powerful four-channel amplifier platform with Lake? Processing, Dante networked signal distribution.

Power Amplifier

The power amplifier platform of the PLM 20000Q integrates several new developments to maintain reliable, sustained output at unprecedented power levels. The Regulated Switch Mode Power Supply (R.SMPS) is a new universal design that connects to any mains supply in the world. (Operating range is 100 V - 265 V, but new Under Voltage Limiting extends operation down to 65 V with reduced output power.) The design also incorporates power factor correction (PFC) to reduce peak current draw from the mains.

Load Verification and Continuous Performance Monitoring

The PLM 20000Q includes a revolutionary set of tools for accurate load verification and real-time performance monitoring. The key to both features is LoadLibrary, a comprehensive database that provides unique ?Fingerprints? (load characteristics) for each loudspeaker model in the system.

Lake Processing

The PLM 20000Q contains two Lake Processing modules, each offering precise settings for gain, delay, crossover slope, equalization, and limiting. Exclusive Lake Processing algorithms are included for Raised Cosine Equalization, linear phase crossovers, LimiterMax loudspeaker protection, and Iso-Float ground isolation. Raised Cosine Equalization is the foundation for the Lake Mesa EQ and the Ideal Graphic EQ. Mesa EQ offers asymmetric filtering to match the asymmetric responses of many loudspeaker systems the Ideal Graphic EQ offers true sum-to-flat response, so the adjustments provide uniform boost and cut along with greater selectivity.

Lake Controller Software

Lake Controller software provides a unified interface for control and monitoring of all functions of the PLM 20000Q. In addition to controlling all parameters of standard Lake Processing, new versions also provide control and monitoring of exclusive PLM features: digital input gain and attenuation, and load verification and performance monitoring via LoadSmart and SpeakerSafe. The Lake Controller software is optimized for a wireless Tablet PC. The same Lake Controller interface can be used to operate Dolby Lake Processors, Lake Contour, and Lake Mesa Quad EQ processors as part of a unified system.

Dante Digital Audio Network

PLM Series Powered Loudspeaker Management systems are equipped with Dante, a self-configuring digital audio networking solution from Audinate of Australia. Based on the newest developments in networking technology, Dante provides reliable, sampleaccurate audio distribution over Ethernet with extremely low latency. Dante incorporates Zen, an automatic device discovery and system configuration protocol which enables PLM Series products and other Dante-enabled products to find each other on the network and configure themselves.

Used LAB.Gruppen


LAB.Gruppen is a Swedish sound equipment company, based in Kungsbacka, Sweden, dedicated to building mainly public address power amplifiers. It is owned by Music Group which also holds Midas, Behringer, Turbosound, TC Electronics and others. As of 2007 the company had 130 employees.
Kenneth Andersson and Dan Bävholm founded Lab.gruppen in 1979. They first met as schoolboys when they shared an interest in electronics.Andersson and Bävholm's first project was a hand-made mixing console. It was used as part of the Front of House equipment for a concert by Eartha Kitt. They created other mixers and a series of guitar heads and combos. Their intermittent manufacture of mixers and guitar amplifiers continued through the formal establishment of Lab.gruppen in 1979.
The company was located inside a local hi-fi store, where the duo serviced consumer equipment for additional income. It was here that the company's first professional audio power amplifier was created.
Between the LAB 4000 and FP Series 6400, Lab.gruppen engineers continued to advance and refine their products. The LAB Series was overhauled and augmented and subsequently became the FP range. FP designs were upgraded to meet the stringent new EMC standards in Europe, and adoption of UL safety standards allowed them to be sold in the United States. Standardization of internal components between models increased manufacturing efficiency to keep pricing competitive in all new markets.
In the late 1990s, the founders brought in new ownership and a managing director. In July 2000, Lab.gruppen was acquired by the TGI Group of the United Kingdom, and a few months later Tomas Lilja was chosen as managing director.
In early 2002, the TGI Group was acquired by TC Group of Denmark, the current corporate owner. In 2004, the company moved to its new location at Faktorvägen. Both Andersson and Bävholm remained with the company following the acquisitions.
In 1998, Lab.gruppen engineers undertook the long-term development of a new amplifier platform. The complete range would have four bridgeable amplifier channels and an integrated monitoring and control network. The basic technology of both the power supply and output stages was taken from the proven FP range, but with significant upgrades to reduce the number of components required.
Designated the C Series and targeted at the installation market, the first amplifiers of this design were shipped in the summer of 2005. This was followed up by the release of FP+ in 2006 and PLM Series in 2007.
The PLM Series was the first Lake processor with integrated amplification and it as it was embraced by the market Lab.gruppen acquired the exclusive rights to the Lake brand and the Lake processing for professional applications in touring and fixed installations late 2008.
The E Series was the first amplifier range with more than 200 W per channel that got the Energy Star approval when it was launched in 2011. More amplifiers with Energy Star were added with the LUCIA models in 2013.
In 2014, Lab.gruppen launched D Series for installations with audio over the network and PLM+, a successor to PLM Series.
In 2015, Lab.gruppen and the other brands of TC Group were acquired by Music Group.
In 2016, Lab.gruppen expanded the E and LUCIA product lines so that there are now 15 models with Energy Star.

Octave: The difference between two frequencies where one is twice the other. For example, 200 Hz is an octave higher than 100 Hz. 400 Hz is one octave higher than 200 Hz.

Optical Digital Cable: Fiber optic cable that transfers digital audio signals as light pulses.

Outcue/Outq/Out-Point: These words all refer to the final few seconds of audio signifying the conclusion of the production.

Package: A completed and fully edited audio piece.

Passive: Not active. A passive crossover uses no external power and results in insertion loss. A passive speaker is one without internal amplification.

Phase: Time relationship between signals; it’s all relative.

Power Output: A measure, usually in watts, of how much energy is modulated by a component.

Preamplifier: A control and switching component that may include equalization functions. The preamp comes in the signal chain before the amplifiers.

Pre Outs: Connectors that provide a line-level output of the internal preamp or surround processor.

Pre Outs/Main Ins: Connectors on a receiver that provide an interruptible signal loop between the output of the internal preamp or surround processor portion of the receiver and the input of the amplifier portion of the receiver.

Pre/Pro: A combination preamp and surround processor.

Processors: Anything that processes an incoming signal in some way. Surround processors, for example, can decode a Dolby Digital signal to send to an amp so you can hear it.

Pulse Code Modulation: (PCM) a way to convert sound or analog information to binary information (0s and 1s) by taking samples of the sound and record the resulting number as binary information. Used on all CDs, DVD-Audio, and just about every other digital audio format. It can sometimes be found on DVD-Video.

Q-and-A: Question and answer session.

Receiver: Any component that receives, or tunes, broadcast signals, be it NTSC, HDTV, DBS, or AM/FM radio. Typically refers to the single component that includes a preamp, surround processor, multichannel amplifier, and AM/FM tuner.

Reverberation: The reflections of sound within a closed space.

RF: Radio Frequency. Television signals are modulated onto RF signals and are then demodulated by your television’s tuner. VCRs and DBS receivers often include channel 3 or 4 modulators, allowing the output signal to be tuned by the television on those channels. Also, laser discs used an RF signal for modulating Dolby Digital 5.1 soundtracks on some movies. This requires an RF demodulator (usually referred to as an AC3-RF demodulator) before or in the surround processor to decode the signal.

RMS: Root Mean Square or the square root of the arithmetic mean (average) of the square’s set of values. A reasonably accurate method of describing an amplifier`s power output.

SACD: Super Audio CD. Enhanced audio format with up to six channels of high-resolution audio encoded using DSD. Requires an SACD player. Multichannel also requires a controller with six-channel analog or proprietary digital inputs for full playback.

Sampling Frequency: How often a digital sample is taken of an analog wave. The more samples taken, the more accurate the recording will be. You need to sample at a minimum of twice the highest frequency you want to capture. For example, the 44.1-kilohertz sampling rate of a CD cannot record sounds higher than 22.05 kilohertz.

Scener: A radio report in which the announcer is recorded at the same time and place as the background sound of an event.

Sensitivity: A measurement (in dB) of the sound-pressure level over a specified frequency range created by a speaker driven by 1 watt (2.83V at 8 ohms) of power with a microphone placed 1 meter away.

Signal-to-Noise Ratio: A comparison of the signal level relative to the noise level. Larger numbers are better.

Simultaneous Interpretation: This system allows attendees to hear the meeting in their own language.

Sound Bite: A portion of audio of someone speaking.

Sound field: The total acoustical characteristics of a space, such as ambience number, timing, and relative level of reflections; ratio of direct to reflected sound RT-60 time etc.

Soundstage: The area between two speakers that appears to the listener to be occupied by sonic images. Like a real stage, a soundstage should have width, depth, and height.

Speaker: A component that converts electrical energy into acoustical energy.

SPL: Sound-Pressure Level. Measured in dB.

Subwoofer: A speaker designed to reproduce very low bass frequencies, usually those below about 80 Hz.

THX: Certification program for home theater equipment. Uses some proprietary features, but mostly assures a base quality level for a given room size. (See THX select or Ultra.) Is compatible with any and all soundtrack formats. Stands for either Tom Holman’s eXperiment, after the engineer who drafted the original standard, or is named after the company’s founder George Lucas first movie, THX 1138. Nobody agrees on which.

THX select: Certification program for speakers and receivers that assures a base level of quality and performance when played in a room that’s between 2,000 and 3,000 cubic feet.

User-Generated Content (UGC): Text, photos, video or audio supplied by the customers of a company.

Voicer: A radio report without background audio taken from a scene or otherwise.

Wrap: A radio report containing both the reporter and an actuality.
