Under OUTPUT LEVEL you can switch between +4dBu to set the output level of each individual
line output pair optimized for balanced audio signals to +4dBu studio standard level or -10dBV to
set the output level optimized for unbalanced audio signals to -10dBV consumer/HiFi standard
level.
The S/PDIF STATUS BIT section allows you to define if the S/PDIF output signal is sent with a
status bit for PROFESSIONAL or CONSUMER signals.
Under it, the current SAMPLERATE is displayed.
3.1 Latency settings
Under Windows via Config > Latency in the Control Panel it is possible to change the latency
setting (also called “buffer size”) for the driver of U86 XT. A smaller latency is the result of a
smaller buffer size and value. Depending on the typical application (e.g. for playback of software
synthesizers) a smaller latency is an advantage. At the same time, the best latency setting indirectly
depends on the performance of your system. For recording applications, a typical latency buffer size
between 4 and 8ms is standard, a value displayed typically inside your audio application. Note that
the latency has to be setup before launching the audio application using U86 XT.
Under Mac OS X, the latency is depending on the audio application and usually setup there inside
the settings of that software.
