Owner Insights

We analyzed real musician discussions from forums and Reddit to find what players love, question, and tweak about QSC PLX3602.

Use cases and applications

  • The PLX3602 can handle a 2.6Ω stereo setup with mixed 8Ω and 4Ω subs, though power distribution will favor the 4Ω subs.

    Source

Setup and maintenance

  • Running the PLX3602 at loads below its 2Ω per channel rating risks overheating and reduced power output, especially with varying driver impedances.

    Source
  • Bridging the PLX3602 at 1kHz for 3600W output can be misleading; ensure sub ratings match for effective power distribution.

    Source

Features and functionality

  • It's noted that running the PLX3602 in bridged mode below 4Ω is not recommended due to potential thermal issues and its sensitivity to low voltage conditions.

    Source
  • The PLX3602 can be used with a dbx 223 crossover in mono mode for fine-tuning crossover frequencies, even if the amp has built-in functionality.

    Source

Comparisons

  • Older amps like the Macrotech 5002 are mentioned as better suited for low-impedance loads compared to the PLX3602, which is less tolerant of such demands.

    Source
  • The b&c sub18 reflex with tbx or rbx drivers is recommended for cost-effectiveness and simplicity in pairing with the PLX3602.

Critic Reviews

Review: QSC PLX2 Series — AudioTechnology

audiotechnology.com

QSC’s PLX3602 stands out as a stellar switch-mode amplifier, offering clean sound and robust protection circuitry at a reasonable price. Its lightweight design (under 10kg) and ample power delivery, with 725W per side into 8Ω and up to 3600W bridged into 4Ω, make it an attractive option for budget-conscious buyers. While the PLX1104 and PLX1804 lack a bridge mode switch, the series overall impresses with user-configurability and useful filters. The PLX2 range is a compelling choice for those cautious of switch-mode amps, providing high-quality performance without breaking the bank.
