LAB.GRUPPEN PLM 10000Q: This first in the PLM Series of Powered Loudspeaker Management systems was created by Lab.gruppen and Dolby Labs, seamlessly integrates the functions of crossover, delay, EQ, limiting and 10kW of power amplification in a single chassis with an accompanying software controller for a complete drive system. This affords an unprecedented level of user control, reconfiguration flexibility and precise system tuning with load verification/monitoring features to assure extended reliability for all system components, including loudspeakers. Price $8,995. AES booth #331.

MARTIN MA SERIES AMPS: Three new MA Series amps use lightweight, high-efficiency PWM technology to deliver up to 95% of the input power to the speakers with only 5% lost as heat dissipation. The series features comprehensive DSP functionality that is accessible from the front panel controls and LCD. Limiting, mains current draw, level and routing can all be controlled, and functions can be remotely operated and monitored by a PC via an RS-485 interface. An optional DSP card adds more functionality from onboard SHARC processing; a smart card can store and load parameters between amplifiers.

QSC POWERLIGHT 3 SERIES: With three models ranging from 2,500 to 8,000 watts, QSC's PowerLight 3 Series amps offer a choice: DSP with remote control and monitoring via BASIS, or straightforward analog input operation—all from two-rackspace units.
