The DN-A7100 AV pre-amplifier is compatible the with most advanced surround sound formats, and because of its unique design, the DN-A7100 is ideal for any installation that requires high-quality, channel separated audio outputs - in particular those installations where adapting unbalanced RCA preamp outputs is completely unacceptable, or the extra weight of unused consumer power amps is not needed. Many installations now require surround sound decoding - From big installations with many multiple amps driving line array systems to small boardrooms and private theatres with active monitor systems, the Denon Professional DN-A7100 is the most affordable, professional option.
