The PLX2 series is a range of premium quality, high-power amplifiers designed for the most demanding live performance uses. Built on the third generation of QSC PowerLight technology, PLX2 amplifiers combine light weight, superlative audio quality and proven QSC reliability.
The PLX3102 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 PLX3102 features built-in subwoofer processing, filter switches, and front panel indications of bridge mono status.SPECIFICATIONSSTEREO MODE, both channels driven *8 ohms FTC 20 Hz - 20 kHz 0.05% THD: 550 W EIA 1 kHz 0.1% THD: 600 W4 ohms FTC 20 Hz - 20 kHz 0.05% THD: 900 W EIA 1 kHz 0.1% THD: 1000 W2 ohmsEIA 1 kHz 1% THD: 1550 WBRIDGE MONO MODE *8 ohms20 Hz-20 kHz 0.1% THD: 1900 WEIA 1 kHz 0.1% THD: 2100 W4 ohms1 kHz 1% THD: 3100 W • Signal to Noise (20 Hz - 20 kHz): -107 dBInput Sensitivity @ 8 ohms: 1.23 Vrms• Gain @ 8 ohms: 35 dB• Output Circuitry: 2-Step Class H• Distortion (SMPTE-IM): Less than 0.02%• Typical Distortion: 1/8 rated power, 20 Hz-20 kHz: Less than 0.02% Full rated power, 20 Hz-20 kHz: Less than 0.02%• Frequency Response: 20 Hz-20 kHz, -0.5 dB• Damping Factor: Greater than 500• Input Impedance:20k ohms balanced10k ohms unbalanced• Input Clipping: 11 Vrms (+21 dBu)• Cooling: Variable-speed fan, rear-to-front air flow• Input Connectors, each channel: 3-pin XLR and 1/4" TRS balanced• Output Connectors, each channel: Neutrik NL4 Speakon and Touch-proof binding posts(Both channels available on Ch 1 NL4 connector)• Rear Panel Switches:Input Configuration: Bridge/Stereo/ParallelClip Limiters each channelFilters (per channel): Top 100 Hz HPF/Full/Sub 100 Hz LPF & 33 Hz HPF/Full (infrasonic)• Front Panel Controls:Detented Input Attenuator: 0 to 8 dBPower On/OffFront Panel Indicators Clip: Red LED-10: Green LEDSignal (-35 dB): Green LEDPower: Blue LEDParallel: Amber LEDBridge Mono: Amber LEDPROTECTION• Amplifier Protection: Full short circuit, open circuit, thermal, infrasonic, ultrasonic, and RF protectionStable into reactive or mismatched loads• Load Protection On/off muting, DC-fault power supply shutdown• Infrasonic -3 dB, 5 Hz• DC fault: Power supply shutdown• Ultrasonic: -3 dB, 85 kHz• Short Circuit: Cutback• Thermal: Muting at 90 COver Current:Active clip limitingPower spply cutback• High Line: Standard +15%, survive +25%• Low Line: -33%PHYSICAL• Dimensions Height: 3.5" (8.9 cm) 2 rack spaces Width: 19" (48.3 cm) Depth, Rack mounting surface to rear panel: 12.8" (32.6 cm) Overall Depth: 14.875" (37.9 cm)Weight 21 lbs.
