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:
