The 518 Digital Audio Processor is a consumer product based directly on the well proven technology of 618 Digital Mastering Processor.
The 518 Digital Audio Processor can provide a most stunning replacement for an audio preamp. In this application, the 518 sits between digital sources like CD or LaserDisc and a Digital/Analogue converter (DAC) which is connected directly to a power amp or active loudspeakers. In this very straight-line architecture, the conventional analogue preamp is not required and the improvement in transparency is remarkable. This Control Unit also enhances resolution by providing options for word-length expansion and adaptive pre-emphasis. Four sources can be connected to 518 each remembering settings for the precision of the incoming signal. All incoming sources are de-jittered using the twin PLL stabiliser. More sources can be catered for (including analogue) by adding a Meridian 562. The 518 provides a remarkable 72-bit DSP volume control, the output of which is re-dithered to exactly match the precision of your DAC. All features including volume, mute, standby and source are remotely controllable using a Meridian MSR, 500 Comms or the 518’s RS232 port.
