Datasat RA7300

Datasat RA7300 7 channel 300W class AB. One of the greatest multichannel amps ever built at any price. If you are looking for a class AB amp for warmer and more extend highs with massive current with 2 power cords for thunderous bass, this the perfect amp for your entire surround system or beaming the fronts. Excellent condition. I also have a Trinnov Amplitude 8 eight channel amp. I dont need both. Looking to sell one. This is incredibly heavy about $150 pounds. I have original box. Rare opportunity. Beautiful Datasat faceplate but works perfectly with any processor. Can use it for my 6 Atmos speakers but it deserves a much more prominent role somewhere. About 3-4 years old. I originally bought new from an authorized dealer and had it shipped to me directly from Datasat. Paypal add 3%. Will take wire, check, or PayPal family Friends option. Will consider trades and offers. --------------------------------------------------------------------------------------------------------
The Datasat RA7300 Multi-Channel Power Amplifiers bring a new level of quality and flexibility to high-end home theatre and multi-channel music systems. Perfect for anything from small media systems to dedicated top of the line home cinemas or even to outfit an entire home or estate, its advanced circuitry and careful design delivers one of the industry’s most powerful, versatile and quietest power amplifiers.
The fully balanced differential design of the RA7300 doubles amplifier speed (slew rate) while reducing noise by 50%. Dual thermal sensors control very low speed fans with substantial heat sinks. The fan only operates when program material requires additional cooling to ensure fan noise is always masked by the content. In addition, dual DC servos ensure DC offset is minimised and thermal track transistors maintain the amplifier at its optimum bias point independent of its temperature.
The result is consistently low distortion and extremely quiet operation that provides highly accurate and refined music and soundstage reproduction. The RA7300 can support the latest multi-channel digital surround sound formats for outstanding audio quality even in the most demanding operating conditions.
The RA7300 is designed to be versatile and is rated for 4 and 8 ohm loads. With a rated output of 300 watts RMS into seven channels at 8 ohms, the RA7300 is powerful enough to deliver consistently excellent performance in any system.
The RA7300 amplifier is deigned to complement Datasat’s RS20i high-end audio processor as well as the RA2400 stereo amplifier providing the ultimate listening experience for luxury home cinema. Power Output 300 watts RMS x 7 channels @ 8ohms 450 watts RMS x 7 channels @ 4ohms
