    Lab.gruppen will unveil its new model of the PLM Series of Powered Loudspeaker Managements systems at ProLight+Sound/Musikmesse 2010 in Frankfurt.

    The new PLM 20000Q is designed to integrate two modules of updated Lake Processing with four channels of power amplification, each rated at 5000 watts peak output. It is housed in a 2U chassis weighing 16 kg (35 lbs).

    According to Lab Gruppen, "the PLM 20000Q is 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, 70 V distributed systems, or any combination thereof."

    A new universal power supply with power factor correction (PFC) is designed to allow 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, the manufacturer says.

    Lab Gruppen says the PLM 20000Q is rated at 5000 watts peak output per channel with all channels driven into optimum impedance interval of 2.0 – 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%.
