A commonly used cable today is Ethernet cable. You are probably most familiar with its use involving the internet in your home, mostly going from your modem, to another computer of to a Wi-Fi router. However, the use of Ethernet cable has been instrumental in the changing would of technical theatre. Before its introduction, the most common computer cables used in theatre were DMX and XLR, for lighting and sound respectively. The issue with this is that each cable can only carry the information for one device, be that a microphone or light. In addition, if these cables are stored improperly, they can corrupt the information being transmitted. Ethernet is much smaller, and can transmit far more data. Also, there is less of a danger regarding storing cable. Ethernet, combined with new operating system and equipment, has made things far more efficient. For example, an analog board must have one XLR cable go to each microphone, so if you wanted to run 40 microphones, you must have 40 channels available on your soundboard. Also, the size of a cable with 40 smaller lines inside it can reach a one-inch diameter, and can weigh several hundred pounds. Now, a digital soundboard can control up to 100 microphones on a single Ethernet cable. 2ff7e9595c
