Does anyone know what the optical in is for on the back of this device, I can use analogue in/out and optical out. Thing is I just can’t get to grip with digital optical in. Thanks in advance
you can use any of these units to record media to your your Sony deck. there must be a setting for optical in for accessing component. check page 26 in your manual. link below to download. Connect a component such as digital amplifier, CD player, DAT deck, or MD deck through the DIGITAL OPTICAL IN/OUT jacks (S/PDIF square type) with a optical digital cord (not supplied). Be sure to insert the plug until it clicks into place. Optical digital cord (not supplied) https://www.manualslib.com/download/159179/Sony-Rcd-W100.html
