Lab.Gruppen reveals the most powerful amplifier: PLM20000
Lab.gruppen is delighted to unveil the new flagship of the acclaimed PLM Series of Powered Loudspeaker Managements systems at ProLight+Sound 2010 in Frankfurt. The new PLM 20000Q seamlessly integrates two full-featured modules of Lake Processing with four channels of power amplification, each rated at 5000 watts output. This prodigious output capacity makes the PLM 20000Q easily the most powerful four-channel amplifier solution on the market. Because everything is housed in a 2U chassis weighing a modest 17 kg (37 lbs), the PLM 20000Q affords unprecedented power density for even greater utility in all types of sound reinforcement applications.By combining enormous power with industry-leading Lake loudspeaker processing, the PLM 20000Q is singularly capable of driving any loudspeaker system or array - of any size or configuration. No other amplifiers or processors are needed, whether the load comprises subwoofers, high frequency drivers, full range loudspeakers, and constant voltage distributed systems, or any combination thereof.
"It's no longer necessary to split configurations across several amplifier types," observes Miguel Hadelich, VP Touring Market, TC Group International. "Rack configuration and inventory management can be vastly simplified, saving time and labor costs."
The PLM 20000Q incorporates several new developments to maintain rated performance even with extreme program demands or under marginal operating conditions. A new universal power supply with power factor correction (PFC) allows extended bursts without sagging rails; extreme low frequency beats will not affect mid- and high-frequency headroom. Also, with a differentiated load on the four outputs, a higher wattage can be delivered to the more heavily loaded channel while peak voltage remains accessible on all channels. In addition, new limiter profiles (developed in consultation with leading end-users) result in improved subjective performance when the desire for increased SPL exceeds allowable limits.
Finally, to assure uninterrupted service when pushed to extremes, the PLM 20000Q employs the proprietary Breaker Emulation Limiter (BELTM) (to prevent tripping of mains breakers) along with advanced peak limiting circuits that keep output devices inside operating tolerances and below the thermal protection threshold. And when confronted with sagging mains voltage, new Under-Voltage Limiting (UVLTM) allows continued operation even when mains supply is as low as 65 V.
The robust amplifier platform works hand-in-glove with dual integrated Lake Processing modules. In addition to exclusive Lake features such as Raised Cosine EqualizationTM, Limiter MaxTM peak and RMS limiters, and Iso-FloatTM ground isolation, the input and DSP sections of the PLM 20000Q also include AES3 digital and Dante networked inputs, primary and secondary network connections, digitally implemented zero-overshoot Inter Sample Voltage Protection Limiting (ISVPLTM). LoadSmartTM load verification and SpeakerSafeTM loudspeaker performance monitoring ensure trouble-free performances. All PLM Series products are controllable via the Lake Controller software application, and all are fully compatible with the new LM 26 Lake Processor, Dolby Lake Processors, and other legacy Lake processors.
The PLM 20000Q delivers 5000 watts output per channel with all channels driven into optimum impedance interval of 2.2 - 3.5 ohms. Output per channel into 4 ohms is 4400 watts, all channels driven. Peak output voltage is 194 V, while THD +N at 1 kHz and 1 dB below clipping is <0.04%.
