The MEDUS employs a twin metal frame. The inner chassis is made of steel and acts as a very effective shield against electrostatic and electromagnetic radiation. The outer frame is made of massive anodized aluminium for additional shielding, resulting in optimal heat convection and beautiful looks.
A powerful non-switching power supply is used. All sensitive voltages have their own regulators which are separated between left and right channels. The result is an analog output free of “digital noise” and channel crosstalk. The power switch activates a semiconductor relay which only switches on or off at zero crossings of the mains voltage. This assures a glitch free power switching. The mains transformer sits in a mu-metal shielding box.
The MEDUS is synchronized by the input signal present at the selected input. Several signal re-clocking schemes are combined for extremely high jitter attenuation down to subsonic frequencies, making the MEDUS virtually immune to jitter. With the USB or Firewire inputs the master clock is generated by the MEDUS.
There are a total of four inputs with the following input sockets:
- Input #1: AES/EBU on XLR or RCA
- Input #2: AES/EBU on XLR or RCA
- Input #3: AES/EBU on XLR or USB
- Input #4: AES/EBU on TOSLINK/DLNA or RCA
Sampling frequencies can be 44.1, 48, 88.2, 96, 176.4 or 192 kHz. Inputs #1 and #2 can be used for the dual wire scheme of transferring 88.2 kHz…192 kHz data. All inputs accept up to 24 Bits of data word-length. Optional inputs are Firewire or ST type glass fiber.
