About the QSC PLD4.5
The QSC PLD4.5 is a workhorse four-channel touring amplifier with FlexAmp — assignable power across channels so 4 × 1125W or 1 × 4500W are all valid configurations. Onboard DSP handles crossover, EQ, limiter, and delay; remote control over Ethernet keeps the amp room manageable from FOH. Used heavily on regional touring and corporate AV — popular for monitor amp racks and sub arrays where flexible channel grouping pays for itself.
Four-channel 4500W touring amp. FlexAmp power assignment + onboard DSP.
