OWNERS MANUAL FOR WEISS MEDEA+ D/A CONVERTER
Page: 28 Date: 02/11 /dw
During the test the output of the MEDEA+ is muted.
If the player does not seem to be bit transparent then this can have several causes, like:
- a volume control not at 0dB gain
- a equalizer
- a sampling rate conversion
- a “sound enhancer” feature and more
Make sure all those processing elements are bypassed. Particularly the sampling rate conversion
can creep in “unnoticed”. I.e. the sampling rate in the Weiss Firewire IO window has to match the
sampling rate of the file played, else a conversion is going on in the operating system. For iTunes
there is another thing to know: Whenever the sampling rate is changed in the AudioMidi setup or
the Weiss Firewire IO window, the iTunes program has to be restarted to achieve bit transparency
again. For iTunes running on a Mac computer a program like Sonic Studio’s “Amarra” is highly
recommended. With Amarra it is possible to switch the sampling rate in AudioMidi (i.e. in the
MEDEA+) automatically depending on the sampling rate of the file played. Amarra works in
conjunction with iTunes.
On a Windows based system the use of ASIO or WASAPI is highly recommended. These systems
make it simple to achieve bit transparent playback. In addition the sampling rate of the MEDEA+
is switched automatically depending on the sampling rate of the file played.
Remote Control
To use the remote control feature, the enclosed IR receiver with cable has to be plugged into the
special socket above the Firewire connector at the back of the MEDEA+. The IR receiver end then
has to be placed such that the IR control works flawlessly.
The Remote Control allows to control the volume and the phase of the digital signal transferred
by the firwire interface in the MEDEA+. The volume up / down switches control the volume
accordingly. The maximum gain is 0 dB (a gain factor of 1.0), i.e. the MEDEA+ can not amplify
the signal and thus makes sure that there are no “overs” occuring within the MEDEA+. The
“mute” switch allows to toggle between fully off (muted) and the volume set with the volume
control.
