Have you recently purchased a new sound bar or receiver? If you have, you may have noticed that many newer audio equipment will have a digital audio input that won’t work with your existing analog audio system. Our analog to digital audio converter will allow you to play audio from your current equipment with your new receiver. Simply connect a dual RCA cable from the source device into the converter. Then connect either a digital coax or digital optical cable from the converter into your receiver. And there you have it, analog audio ready to transmit through your digital receiver. Be aware, this converter is not bi-directional and is only designed to be used from an analog output to a digital input. If you need a digital to analog converter, this is what you will need: http://www.showmecables.com/product/D...
