Here is a low-cost modular and flexible way to route and switch your pro-audio inputs and outputs. Inexpensive passive modular boxes can sit alone on your desktop or you can mount up to four boxes in the convenient PPP-000 rack mount kit (1RU). Offers a level of flexibility like none before!
The MXL-369 is a straight through only. Each channel can be reversed.
The MFO-363B works just like an analog half-normalled patch bay. Works for 2 channel S/PDIF and ADAT Litepipe. Includes AC/DC power supply.
