OK. Does the UA5 need to be digi-modded? I am going straight Optical from UA5 into mini-plug JB3
If the UA5 has NOT had a digi-mod performed, it will not output an optical signal unless the UA5 is also connected to a computer via USB. In order to output optical in stock form, the signal must follow this path:
Analog in > gain > ADC > USB out to PC > USB in from PC > optical out
The digi-mod enables the following signal paths so they operate simultaneously:
Analog in > gain > ADC > optical out
Analog in > gain > ADC > coax out
Analog in > gain > ADC > USB out
However, the mod removes the ability to run PC > USB > UA5 > playback system. If the UA5 was originally purchased from the Oade Bros, they'll modify it for a small fee. Alternatively, there are DIY instructions in the Archival Info forum.
