The PLX3602 is an excellent choice for users who need to drive up to four loudspeakers from each amplifier channel (2 ohm loading), or when extremely high power bridge mono operation is required. The PLX3602 features built-in subwoofer processing, filter switches, and front panel indications of bridge mono status.

Features

Very light weight ("02" models, 21 lbs/9.5 kg, "04" models 13 lbs/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.
Speakon NL-4 output connectors provide a positive-locking speaker connection. Ch 1 output uses all 4 wires 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.
Speakon NL4 and binding post outputs.
100 Hz high pass and low pass filters for bi-amping subwoofer and satellite systems without the need for an external crossover.
Switchable/defeatable 33 Hz infrasonic filters protect woofers from over-excursion damage.
Switchable/defeatable clip limiters.
Four models with power ratings up to 1800 watts per channel @ 2 ohms, 3600 watts bridged @ 4 ohms.
