However, Belden 1800F is also 110 ohms impedance for use with digital audio. In fact, this cable started life as digital audio patch cable. It was a high quality cable that is very flexible, and came in many pretty colors. It says right on the cable, "digital audio". If your customer says, "I can't use this on my analog mics because it says 'digital audio’," there's no problem. I will personally send you a bottle of rubbing alcohol. With that you can rub off the word "digital" and the cable works PERFECTLY after that". (source: www.belden.com )
