INTRODUCTION

The C5-DA is a stand-alone device that transforms a coaxial digital audio signal to and 
from CAT-5 twisted pair cabling. It has two sets of simple connections. The first is an RCA 
connector for the digital audio signal. The second is a shielded CAT-5 connector for the CAT-5 
twisted pair connection. The circuitry is passive so there is no need for a power supply. 

The C5-DA allows a digital audio device, such as a CD player, to be located an extended 
distance from the system it is to be connected to. Doing so with conventional audio cabling is 
both expensive and prone to signal degradation. By using a pair of these devices and a run of 
CAT-5 the problem can be solved inexpensively and without signal loss and the introduction 
of noise. In addition, in today’s retrofit market an installer cannot always successfully run a 
wire from point A to point B. There exists however an abundance of twisted pair cabling in 
many homes. By using a pair of these devices with an existing wire an installer may be able to 
complete a job that he otherwise could not.
