QSC RMX 850 Power Amps Review

Posted by admin in QSC on August 4th, 2009

QSC has been among the top players in the sound amplification industry since the 1960s. Their unique combination of innovative technologies, accurate tonal response, and raw power has made them popular with all types of musicians and sound engineers for decades. This tradition has been continued with their QSC RMX 850 Power Amplifiers. The RMX 850 is the entry level amplifier in the RMX series, producing plenty of raw muscle and superlative tone at one of the lowest price points ever.

The RMS 850 is a dual channel power amplifier, capable of supplying up to 830 watts in bridged mono operation or 430 watts per channel in stereo mode, using 2 ohm speakers. It is beloved by musicians, DJs, and home theater aficionados alike as an entry level power amp that refuses to compromise on tonal or build quality. In terms of sound output, the goal of the RMS series is to provide a completely flat response across the entire frequency spectrum, resulting in sound reproduction that is totally accurate. The RMS 850 ably succeeds in this goal, and additionally provides independently selectable low pass filters at 30 Hz or 50 Hz for each channel, protecting speakers that are unable to reproduce subsonic frequencies at high volume levels.

In addition to being able to produce the punchy bass and crisp high end frequencies that professional musicians require, the RMS 850 is built to last. It features durable, heavy construction, quiet internal cooling fans, and the highest quality toroidal transformer to ensure uninterrupted operation for years to come. The RMS 850 does not compromise on internal build quality, either. Each channel has independent fault protection from overloads of either heat or input current, automatically adjusting volume levels or temporarily breaking circuits in order to ensure that the speakers and the amplifier itself are protected in conditions that are less than ideal.

In the entry level pro audio market, it would be difficult to find a better buy than QSC RMS 850 Power Amplifiers. By including unsurpassed build quality and protective circuitry in an inexpensive package, the RMS 850 is an excellent choice for bands that might be new to touring and are still in the club circuit. For bands that regularly play at very large or outdoor venues, it would be better to consider another power amplifier such as the RMX 2450, which has a maximum output capacity of up to 2400 watts.
