The DD AP-1 MDC Module is a device designed to be used alongside an existing NAD compatible stereo amplifier. It gives the user the ability to convert analog sound into digital. The world is becoming more digitized, but that doesn’t mean you have to give up on the classic equipment you love. This simple device gives you the best of both worlds and the capability to handle three different analog audio inputs. The module features a pair of XLR inputs, an RCA stereo input pair and an RCA stereo phono input to suit a variety of needs. This converter allows your stereo amplifier to be able to handle a wider range of analog audio devices, so you can mix and match at your liking.
