QSC RMX4050a 2-Ch Power Amplifier with 850 WPC at 8 Ohms

QSC AudioPart # 245-639
Model: RMX4050a
The QSC RMX4050a amplifier offers true professional quality performance at an affordable price. This power amplifier's compact chassis is only 2 rack spaces high and less than 16" deep. XLR and 1/4" balanced inputs and Neutrik Speakon and binding post outputs allow users a convenient choice of connectors, while user-defeatable clip limiters and selectable low-frequency filters optimize sonic performance.

Key Features

  • High-current toroidal transformers, for greater 2-ohm power and low noise
  • Independent user-defeatable clip limiters reduce distortion
  • Selectable low-frequency filters (30 Hz or 50 Hz) protect speakers and increase headroom
  • Combination of cooling capacity and electrical efficiency provides robust thermal performance suitable for high continuous power in 2-ohm stereo or 4-ohm bridged applications
  • Balanced 1/4" (6.3 mm) TRS, XLR, and barrier strip inputs and touch-proof binding post and Neutrik Speakon outputs
  • Front mounted gain controls for easy access with Signal and clip LED indicators for monitoring performance
  • Independent DC and thermal overload protection on each channel automatically protects amplifier and speakers

Overview

QSC RMX4050a 2-Ch Power Amplifier with 850 WPC at 8 Ohms

The new RMXa Series amplifiers from QSC offer true professional quality performance at a new affordable price. This power amplifier's compact chassis is only 2 rack spaces high and less than 16" deep. XLR and 1/4" balanced inputs and Neutrik Speakon and binding post outputs allow users a convenient choice of connectors, while user-defeatable clip limiters and selectable low-frequency filters optimize sonic performance.

Muscular Power Plant
The power supply is the heart of an amplifier, converting raw AC power from the wall to clean DC for the audio circuitry. The RMXa uses a powerful high-current toroidal transformer and ample filter capacitance to ensure generous energy reserves. This makes a critical difference in sound quality, allowing the amp to effortlessly punch out high level transients, even when driving abusive 2 ohm speaker loads.

Superior Performance
RMXa amplifiers deliver true studio-quality sound. A full complementary output circuit using the highest-grade linear output devices delivers ultra-low distortion (<0.05% THD) and a ruler-flat frequency response. SMT (Surface Mount Technology) triples small-signal component density, enabling QSC to pack up to 2,400 watts of power in a chassis only 2 rack spaces and less than 16" deep. And unlike other designs, RMXa output devices are direct-mounted to the heat sink for optimum thermal coupling and cooling.

Specifications: • Power output, stereo mode (EIA 1 kHz, both channels driven): 850 watts x 2 (8 ohms); 1400 watts x 2 (4 ohms); 2000 watts x 2 (2 ohms) • Power output, bridged mono mode (EIA 1 kHz): 2800 watts x 1 (8 ohms); 4000 watts x 1 (4 ohms) • Distortion (typical): <0.01% • S/N ratio (20 Hz - 20 kHz, 8 ohms): 100 dB • Input sensitivity @ 8 ohms: 1.15V • Voltage gain @ 8 ohms: 64x (36 dB) • Output circuitry: 3-tier Class H • Dimensions: 5.25" (3RU) H x 19" W x 15.9" D • Weight: 68 lbs.
