Speck Electronics MicPre 5.0 - Manual (Page 17)

With only a simple connection, the mix sections of two MP 5.0's can be
summed together and operate like a multichannel mixer.
To link two MP 5.0's, an optional MP50-LINK2 mix link cable is
required. This link cable has RJ-45 modular plugs on both ends. One end
has a "clear" colored plug and the other end has a "red" plug. The MP 5.0
that receives the "red" plug is the unit that will become the master.
The illustration below shows how to link two MP 5.0's.
