The WyreStorm Express EXP-CON-DAC-D is a Dolby Digital to analog audio converter capable of taking up to 5.1ch audio encoded in Dolby Digital Surround from compatible multichannel S/PDIF coaxial or TOSLINK optical digital audio sources and down-mixing to standard L/R analog stereo audio. With inputs selectable via onboard input select switch, converted stereo output signals can then be fed to external devices such as an amplifier, Hi-Fi, recording deck, or powered speakers via standard RCA jacks. If quick, reliable and cost effective conversion of encoded Dolby Digital audio to analogue is a requirement for your project, the EXP-CON-DAC-D makes it incredibly easy to connect modern digital sources, such as AppleTV, Blu-Ray/DVD, DAB, digital computer audio to a legacy analogue sound system without requiring expensive additional conversion equipment.
