to one of the A/D converter inputs. Switching onto a particular input can be carried out in the RTA or RTA SETUP menu. The digital input signal goes straight through the transformer balanced input directly to the DSPs (applicable only when the AES/EBU option is installed). Switching between the analog and digital input sources is done in the SETUP menu. Signal processing is accomplished by the two DSPs. They are succeeded by the D/A converters, which reconstruct the left and right analog signals. Finally, they are sent to the electronically balanced outputs. In the case of an

DSP 1 sends the unprocessed audio signal for the right channel to the second DSP, and processes the signal for the left channel.
