QSC RMX Series QSC 1450 Power Amplifier

The RMX1450 power amplifier steps up the output to 280 watts/channel at 8 ohms; 1400 watts at 4 ohms bridged — with the low distortion you expect from QSC.

QSC RMX Series QSC 1450 Overview

QSC’s RMX Series amplifiers give you clean, dynamic power with the legendary QSC sound quality and reliability that pros depend on. The RMX Series delivers unmatched performance at a breakthrough price.

QSC RMX Series QSC 1450 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 RMX 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.

QSC RMX Series QSC 1450 Superior Performance

RMX 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 ruler-flat frequency response.

SMT (Surface Mount Technology) triples small-signal component density, enabling them to pack up to 2400 watts of power in a chassis with only 2 rack spaces and less than 16″ deep. And unlike other designs, RMX output devices are direct-mounted to the heat sink for optimum thermal coupling and cooling.

The power amp is one of the best amplifiers in Kenya and is worth your money. The power amplifier price in Kenya is affordable yet delivers excellent quality output
