Press the "BYPASS" key and check if the midi LED in the front panel blinks. Disconnect the MIDI In or MIDI out cable. Make sure that the unit is not set to Bypass.
Press "I/O", put Input to S/PDIF and listen and notice if the output meters on the D-Two show the same level as from your reference device in our case we use a Finalizer96K. Press "I/O", set input back to analog. Set the Sample rate and check if the unit can play at 48 kHz. Set the sample rate back to 44,1 kHz.
Pause the CD player. Set the MIX level to ix = 0%, set input to max input. (The output level knob can make a click sound when at approximately 12 o'clock. Check the pot meter for high noise and crackling sounds if so the pot meter may be defect.
Press the "TAB" and notice if the delay time does change as it should. Put MIX pot meter to 100% , check if the unit makes the same amount of repeats as chosen. "TAB" a rhythm and listen if the unit does it. "TAB" both rhythm and tempo on Ultimate Switch Control and see if the unit does respond to it.
