Optical Out
Available settings are: SPDIF, ADAT. While the input adapts to the received signal automatically,
the output needs to be switched manually. In Dig Thru mode with an ADAT signal received, the
output is switched to ADAT automatically with all 8 input channels passed through.

14.1.2 Expert Settings
This menu provides access to the THD compensation parameters of AD and DA conversion, and
an adjustment of the internal clock. It is mainly intended for engineers and technicians. All settings
are automatically stored in the device and automatically loaded when the menu is activated.
Enable Settings
OFF, ON. Default: OFF. When activated, the other setting options are displayed. OFF activates
the factory settings.
THD Comp K2L (K2R, K3L, K3R)
Allows to adjust the correction factor of the AD converter to reduce second and third harmonic,
i.e. a reduction of the harmonic distortion. The
THD Compensation is adjustable in wide ranges,
where 0 corresponds to the RME factory setting.
THD Comp K2 12 (K3 12, K2 3/4, K3 3/4)
Other than the AD the ADI-2/4 Pro
’s DA converter offers no separate compensation settings for
left and right channel. Note: Very high values (10.0k) cause around -60 dB distortion (0.1%). It
is therefore also possible to use K2 and K3 separately and intentionally as an effect. This can
be quite instructive - when one notices that no difference between 0.1% and 0.0001% distortion
is audible.
