With four flexible channels of up to 2000 watts each, lightweight PowerLight universal power supply, DSP on-board for each channel, and all the right connectors, the PLD4.5 is ideal for production and live sound applications.
Features
Flexible Amplifier Summing Technology™ (FAST) drives most any loudspeaker system or configuration by distributing total amplifier power across one, two, three, or all four channels.
Four channels of full function onboard loudspeaker DSP with crossover and parametric EQ filters, limiting and alignment delay eliminate the need for outboard loudspeaker processors.
E Series Entertainment System DSP Tunings are now available for PLD processing amplifiers:
