Setup
The Setup menu holds all general Setup-parameters including parameters normally found in Utility, Level and I/O menus. Basic Operation � Press the SETUP key to enter the Setup page. � Use the ARROW keys to select parameter. � Use the CONTROL wheel to change parameter value. All changes are instantly carried out. Mono/ Stereo In The channel select on Analog Inputs is done automatically via sensing on the Input connectors. Input Select Dial the CONTROL wheel to select between Analog or Digital. Analog Input When "Analog" is selected the D�TWO automatically defaults to the internal 44.1kHz clock as Sample Rate. Digital Input When "Digital" is selected the D�TWO attempts to lock to the S/PDIF Input. During the lock-up period the "DI" display icon blinks indicating none or unacceptable clock, and the Outputs are muted. When lock is achieved the "DI" icon turns solid, and the Outputs are un-muted. Clock Analog Input When Input source is analog the following Sample Rates are available: Internal 44.1kHz - The D�TWO runs at internal 44.1kHz. Internal 48kHz - The D�TWO runs at internal 48kHz. Digital - The D�TWO locks to the incoming Digital clock. Digital Input When Input Source is digital the following Sample Rates are available: Internal 44.1kHz - The D�TWO runs at internal 44.1kHz. Internal 48kHz - The D�TWO runs at internal 48kHz. Digital - The D�TWO locks to the incoming Digital clock. Please note that when using internal clock with external digital audio, the incoming digital audio must be in sync with the D�TWO internal clock in order to avoid slip-samples. ***Rate Mismatch**** This Error message will occur in the display if the D�TWO detects slip-samples. Typically this problem only occurs in very special clock setups e.g. if the D�TWO is running via internal clock, while processing audio from the Digital Input. If the incoming clock and the internal clock does not match the D�TWO will display the above written error message. Out Range Sets the maximum Gain range of the analog Output stage. Range: 2dBu, 8dBu, 14dBu and 20dBu. Analog Out Level Adjusts the Analog Output level. Digital In Gain Adjusts the Digital In level. This parameter is only active when Digital In is selected. Dither Going from one type of bit resolution to a lower, e.g. from 24 bit to 16 bit, you actually loose 8 bits of information. The process of cutting off bits is called truncation and it introduces digital distortion of low level signals, due to the lack of complete signal information. To compensate for this, �dither� must be applied. Dither is a small amount of filtered noise that generates randomization at the noise floor, ensuring a less distorted low level signal. Dithering is relevant only on digital Outputs and it is always the receiving device that determines the number of bits you must dither to. A CDR or a DAT recorder should normally be dithered to 16 bit. Status Bits Sets whether the D�TWO is sending out AES/EBU(professional standard or S/PDIF(consumer standard) status bits. Delay Unit Select ms (milliseconds) or BPM (Beats Per Minute). 13
