8. DIGITAL OUTPUT SETTINGS
8.1
The Ti48 has a number of userselectable digital filters, upsampling rates,
upsampling wordlength, and dither options. In addition, you can select the
output connection to be used, the phase and the signal attenuation level.

please refer to section 12.
CAUTION :
Not all filter/upsampling frequency combinations are suitable for critical
(or pleasant !) listening ! Some combinations will emit a significant amount of
inaudible high frequency noise which may affect the equipment used downstream of
this device. These combinations have been allowed only to ensure continuity of
operation when changing output settings on the fly. See Section 12 for more
information.
As there are many output settings options available, you should be able to tune the
Ti48 to suit your musical tastes and audio system. It would, however, be impossible
for us to advise you on the exact settings to use without listening to your system in
your room ourselves. Therefore, we would strongly recommend that you test and run
in the Ti48 on a single set of output settings and then use the various options to tune
the sound quality once you are familiar with the system. The settings given in the
example in Section 8.3 would be a good starting point.
