Question:  I have to replace an old MX-840 assignment panel with 10 sources / 40 destinations, will one RCS-2700 assignment panel perform the functions of the old MX-840?
Answer:  Up to six RCS-2700 units can be wired together in various combinations for up to a 15-source by 72-destination system. There are six possible combinations of units.  A single RCS-2700 unit has 8 sources of audio and 24 remote destinations, as shown in the figure below. 








Two RCS-2700 units can be connected together to provide either 15 sources of audio and 24 destinations or 8 sources of audio and 48 destinations as shown below. The address switch on the rear panel of each unit must be set with the
correct unit number to determine which configuration is chosen.










Other possible configurations include: 15 sources and 48 destinations (4 units), 8 sources and 72 destinations (3 units), and 15 sources and 72 destinations (6 units).
