Product Description


The PLD Series comprises of three powerful, lightweight, four-channel amplifiers. Each has onboard, advanced DSP and the capability to configure and combine channels in various ways to drive a wide range of loudspeaker systems.

Flexible Amplifier Summing Technology™ (FAST) actively distributes the total amplifier power in various combinations across one, two, three, or all four outputs. This flexibility allows PLD Series amps to drive (for example) four full-range loudspeakers or subwoofers; a high-power subwoofer and a bi-amplified speaker; a single high-power full-range loudspeaker and subwoofer combo; or multiple power-hungry subwoofers from a single, very high output mono-block.
