Nord 1 SE NC 500 MB monoblock digital amplifier. It works with balanced inputs, but adapters are included to be used with RCA Connectors if required. Out put from any preamp goes into the inputs of the Nord. This Nord Class D amp has an output of 500 Class D output power. I have also included a pair of Sparkos op amps if users want to substitute already inserted Sonic Imagery op amp from manufacturer. I have the original box and power leads , Sparkos op amps, and RCA adaptors are included. This unit was made in Cheltenham in the UK by Nord Acoustics.
