Overview

Providing 750 W/channel into 4 ohms and 1250 W/channel into 2 ohms with a lightweight PowerLight power supply, the PLX2502 is ideal for the most demanding live sound applications.

 

FEATURES:

 

  • Very light weight ("02" models, 21 lb / 9.5 kg, "04" models 13 lb / 5.9 kg).

  • Cooling design exhausts hot air out the front, keeping the rack cool. Flow-through heat sinks require no filters that could become clogged.

  • Front panel LED power, clip, -10 dB, and signal present indicators for system monitoring and troubleshooting. 02 models also feature bridge and parallel mode LED indicators.

  • Two Speakon® NL4 output connectors provide positive-locking speaker connections. Upper connector provides both channel outputs on all four poles (Channel 1: 1+, 1-; channel 2: 2+, 2-) for bridged mono or for single-cable connection to bi-amplified speakers.

  • 21-position front-panel gain controls for precise, repeatable amplifier adjustment.

  • Balanced XLR inputs with parallel TRS connectors accommodate all common input connectors and support loop-through operation.

  • Patented PowerLight power supply technology with other patents pending.
