A patchbay includes a front panel, a rear panel, and a circuit board with conducting traces. The front panel has mounted thereon a plurality of XLR/TRS combination jacks, and sets of pairs of TRS jacks. The rear panel has five DB25 connectors. The circuit board extends from the front panel to the rear panel; each set of three conducting traces forms a channel connected to one of the DB25 connectors. The DB25 connectors connect to channels for Mic in, Line in, Preamp out, A/D in, and D/A out, respectively. Each XLR/TRS combination jack is connected to a Mic in channel and to a Line in channel. One of each pair of TRS jacks in the first set is connected to a Preamp out channel and the other is connected to an A/D in channel. Each TRS jack in the second set is connected to a D/A out channel.
