designsystem 0 Posted August 10, 2011 How far on a cat5e cable run can the 12v audio devices work, 60 meters ? or is there a better device that can travel higher distances, this one cost a 10er, bit cheap maybe it seems to work ok just very low, i juiced it up from 10 meters away + -, so its just the ground and data going back to the panel over cat5e solid core, i just used one core each I wander would pairing up help ?

designsystem 0 Posted August 11, 2011 I just rang the wholesalers and the tech guy says it should be fine over 50-60 mtrs, so I wander should i of used a pair for ground and a pair of data coming back to the IP-Encoder or would it matter much? Share this post Link to post Share on other sites
survtech 0 Posted August 11, 2011 What cable does the manufacturer recommend? If you're transporting analog audio, it usually calls for shielded cable. We use 22/2 shielded. Share this post Link to post Share on other sites

survtech 0 Posted August 11, 2011 With analog audio, unless the mic and receiver ends are specifically designed for CAT5 ("balanced" output/input), shielded wire is required to prevent hum and noise. There are audio baluns that can transmit audio over utp. Share this post Link to post Share on other sites
