Preamp - RME Audio ADI-2 Pro User Manual

17.2 Preamp

Preamp: Analog in to Analog out (internal digital routing).
This mode can be activated manually by selecting Basic Mode – Preamp. The device enters
Preamp mode automatically when Basic Mode is set to Auto and no digital input signal and no
USB is detected.
Analog input signals are automatically routed to the analog outputs. Use an analog source to
hear it via the rear analog outputs or the headphone outputs, amplified, EQ'd, processed, level
shifted and impedance or unbalanced/balanced converted.
Default sample rate in this mode is 192 kHz, which represents the optimum in fully available
DSP power and superior sonic transparency. Changing the sample rate manually is possible
and the new value will be remembered.
The below diagram shows that the analog input is sent to all digital outputs simultaneously. Any
DSP setting (EQ, phase etc.) of the analog input will affect all outputs. Furthermore the proc-
essed input signal is then processed independent for both analog outputs once more with the
respective output settings.
Note: To simplify the diagram and to maintain overview USB record is not shown. In all modes
all input signals are sent over USB to the host. In multi-channel mode three separate stereo
pairs, in stereo mode only the stereo analog input.
USB Playback channels 3/4 can only be monitored in multi-channel mode. In stereo mode se-
lecting USB 3/4 plays channels 1/2.
