The QSC RMX 4050a is a professional two-channel power amplifier delivering 1400 watts per channel at 4 ohms. Designed with a dual mono high-current power supply and advanced thermal management, it offers reliable, efficient performance on a standard 15 amp 120V outlet. Ideal for mid to large sound systems, it combines rugged durability with clean, powerful audio output.

## Description

The QSC RMX 4050a Power Amplifier is a heavy duty amp designed for mid-size to large systems and works as hard into 2 ohm loads as most competing amps will at 4 ohms. The three-tier, Class H design is extremely efficient at real world power levels so you always get a powerful, clean sound. QSC designed the RMX 4050a so that less AC current is wasted and more available current goes into producing useful audio power. All this is accomplished with a standard 15 amp plug.

### ⭐⭐⭐⭐⭐ Love the sound
*by B***N on May 10, 2019*

Needed to replace a QSC 1400 at my church, so I stepped up the wattage. Very good choice works great love the sound easy to install.

### ⭐⭐⭐⭐⭐ great product worth the money
*by S***E on February 21, 2018*

this is the second one of these units I have purchased they run forever. great product fast shipping

### ⭐⭐⭐⭐ This amp is clean and runs very well and keeps cool while doing so.
*by F***R on January 25, 2021*

This amp is very heavy and has a heavy startup draw when it is first turned on. My monster power device sees a significant drop in voltage when it is first turned on but it balances back out after a short while. The factory settings as they are preset; lacks sensitivity as in. You seem to get low volume per watt out of the box however, you can tweak this on the back panel with a small non-conductive tool. The sound reproduction is very accurate and clear. It has good mids and average low end. This amp is great for full-range systems that are stationary or a well built professional amp rack with wheels. It is much too heavy to be carrying around without one. If you are going to be moving this amplifier a lot I recommend purchasing the warranty anything this thing hit is going to either damage the unit or whatever it hits. Not recommended for beginners; it's too much of an investment to experiment with. Overall it has the power to be worth the investment. If you want something with better power and less weight I recommend a CVR amplifier that has less weight per watt ratio.
