OWNERS MANUAL FOR WEISS MEDUS D/A CONVERTER
THE MEDUS D/A CONVERTER
The MEDUS is a State Of The Art D/A Converter which handles PCM as well as DSD signals. Both digital and analog sections are
designed with great care for all the details which make the MEDUS a truly remarkable DAC.
Features
Inputs:
There are three AES/EBU inputs on XLR connectors, one on Toslink (optical), three RCA connectors, one USB connector. The
accepted sampling frequencies are 44.1, 48, 88.2, 96, 176.4 or 192 kHz. The USB input also accepts DSD Signals. Sampling
frequencies of 88.2kHz and higher can also be fed using the dual wire scheme, i.e. one cable per channel.
Up-sampling:
Signals at 44.1 or 48 kHz are up-sampled in the MEDUS’ DSP chip, using our own studio quality up-sampling algorithms. Thus
the DAC chip always receives signals at a 88.2kHz minimum sampling rate.
Synchronization:
Several signal re-clocking schemes are combined for extremely high jitter attenuation, making the MEDUS virtually immune to
jitter over a very wide bandwidth.
Converters:
The DAC chip up-samples the input signal to about 1.5MHz. Four D/A conversion channels are used per audio channel,
resulting in exceptional performance specifications. The I/V conversion after the DAC chip uses two of our own discrete OP-
AMPs (the OP1-BP) per channel.
