Digital mixing consoles inherently introduce conversion between analog and digital signals. Since digital signals are practically immune to noise, it is preferable to use them for long cable runs. As a result, many modern stage boxes contain an array of DACs and ADCs. This allows all the signals to be transmitted over a single twisted pair cable rather than a bulkier and more expensive analog multicore. Digital stage boxes are typically easier to set up and more reliable than their analog counterparts, and their cables are much more compact. Some digital stage boxes are designed for use with analog mixers, and this type include a corresponding converter box which is located at the mixing console. This converts the input signals back to analog to feed in the mixer. Others are intended for use with a digital mixer, and a cable can be connected directly from the stage box to the mixer, or through an Ethernet switch in some cases.
