QSC PLX1104 เพาเวอร์แอมป์ เครื่องขยายเสียง Low-Z Power Amplifier 550W/ch @ 4 ohms, 325W/ch @ 8 ohms

PLX2 Series Features

All models

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

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

o   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.

o   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.

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

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

o   Patented PowerLight power supply technology with other patents pending.

04 models

o   Value combined with uncompromised PLX technology, quality and performance for applications that don't require bridged or 2-ohm stereo operation.

o   Two models with power ratings up to 900 watts per channel @ 4 ohms.

o   Clip limiting protects speakers; thermal limiting maintains operation even during abnormal overloads.

02 models

o   Speakon® NL4 and binding post outputs.

o   100 Hz high pass and low pass filters for bi-amping subwoofer and satellite systems without the need for an external crossover.

o   Switchable/defeatable 33 Hz infrasonic filters protect woofers from overexcursion damage.

o   Switchable/defeatable clip limiters.

o   Four models with power ratings up to 1800 watts per channel @ 2 ohms, 3600 watts bridged @ 4 ohms

Audio Quality
PLX2 audio power circuitry achieves performance normally associated with studio reference amplifiers. In order to reduce crossover distortion, precision bias tracking makes minute adjustments as amplifier temperature changes. The benefit is cleaner high-frequency and more consistent sound no matter how hard the amplifier is driven..
