INTRODUCTION  
Congratulations on your purchase of the GefenTV Digital Audio to Analog  
Adapter. Your complete satisfaction is very important to us.  
GefenTV  
GefenTV is a unique product line catering to the growing needs for innovative  
home theater solutions. We specialize in total integration for your home theater,  
while also focusing on going above and beyond customer expectations to ensure  
you get the most from your hardware. We invite you to explore our distinct  
product line and hope you nd your solutions.  
The GefenTV Digital Audio to Analog Adapter  
The Digital To Analog Audio converter box takes your coaxial/optical (S/PDIF or  
TOSLink) digital audio source and converts it to standard analog left/right audio,  
available for connection to an external device such as an amplier or recording  
deck via standard RCA-style jacks. Now you can bridge your legacy sound  
system with digital sources such as DVD and CD players that don’t have RCA-  
style analog outputs.  
How It Works  
Simply run a short extension cable from an available digital audio output jack on  
your digital source device to the same type of digital input on the Converter.  
Select which kind of digital signal (coaxial or optical) is being input with the  
selector switch on the converter, then hook up your analog RCA-style left and  
right cables to the Converter’s analog RCA jack outputs and power up all  
equipment. That’s all there is to it!
