Units Parameters
The Units parameters configure the individual hardware units in your system. They are
spread over three tabs: General, Inputs, and Outputs.
General Tab
The settings in this tab control a variety of features, such as the clock source, UV22HR
dithering algorithm, and level meter behavior.
 Clock Source pop-up menu: Sets the clock source for the chosen unit. Options are
Internal, Optical, Coax, and Word Clock.
 Format section: These settings determine the format of the optical input and output
channels. Options are ADAT/SMUX and S/PDIF.
 UV22HR pop-up menu: This specifies the target signal path for the UV22HR dithering
algorithm. Options are Off, Analog In 1–2, Analog In 3–4, Analog In 5–6, Analog In 7-8,
Optical In 1–2, Optical In 3–4, Optical In 5–6, Optical In 7–8, S/PDIF In, and S/PDIF Out.
 Sample Rate Conversion section: The Conversion pop-up menu allows you to enable
sample rate conversion for the S/PDIF Input or Output signal path. If you decide to
engage sample rate conversion on the S/PDIF Out channel, you can set the
destination sample rate in the Sample Rate pop-up menu (next to the Conversion
pop-up menu). Sample rate options are 44.1, 48, 88.2, and 96 kHz.
