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 issue
to consider: Whenever the sampling rate is changed in the
AudioMidi
setup or
the
Weiss Firewire IO
window, the iTunes program has to be restarted to regain
bit transparency. For iTunes running on a Mac computer a program like Sonic
Studio’s
Amarra
is highly recommended.
Amarra
switches the sampling rate in
AudioMidi
(i.e. in the
INT203
) 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
INT203
is switched automatically depending on the sampling rate of
the file played.

Remote Control
If you have acquired the remote control (fig. 2.4) for the
INT203
then you can
control the volume and the polarity of the digital output signal transferred by the
INT203
. The volume up/down switches (
4
/
5
) control the volume accordingly.
