OWNERS MANUAL FOR WEISS MEDUS D/A CONVERTER
ADDENDUM FOR THE FIREWIRE INPUT FEATURE
The Firewire version of the MEDUS adds a Firewire input for direct audio file playback from a
computer at sampling rates of up to 192kHz. Additional features of the Firewire version are:
-
Firewire socket in place of one of the XLR sockets
-
Bit transparency check
-
Possibility to add a Thunderbolt to Firewire adapter for playback via a Thunderbolt output
equipped computer
Synchronization:
When the Firewire input is selected, the synchronization master always is the MEDUS unit, i.e.
the computer is slaved to the MEDUS. The sampling rate is set via the Weiss Firewire IO window.
On a Mac system the sampling rate set in AudioMidi sets the one in the Weiss Firewire IO window
and vice versa. With the proper (advanced) player software the sampling rate of the MEDUS is
switched automatically depending on the track played. For more information on this topic see the
paragraph on bit transparency checking. The MEDUS’ Firewire interface intrinsic jitter is very low.
Software features:
The Firewire interface allows for the testing of the bit transparency of the music player program
running on the computer. This is useful to find out the proper settings / configuration of the player
program to achieve bit transparency. Bit transparency means that the bits fed from the hard-disk
to the MEDUS are not changed in any manner.
