Trunk Line - brings audio to rear panel
There are three types of case for your RS Integrator modules: the rackmountable RS-10 and RS-15, plus the freestanding RS-8000. Whichever combination of these you choose, your access to the modules themselves will always be via the inputs and outputs on their front panels. In most situations this is ideal, but there may be occasions when you would like to make permanent or semi-permanent connections without trailing long cables across the front of the Integrator.
The RS-250 Trunk Lines is the means by which you accomplish this.
