Digital audio signals can be transmitted in either direction
Does not include any digital cables; if needed they must be purchased separately
PCM, Dolby Digital and DTS signals can be passed through this unit
Conversion between digital formats is NOT supported, you can only use units with Toslink or mini optical digital jacks
Note that the supplied Toslink to mini digital optical adapters have a protective plastic cover on the tip which must be removed prior to use.
