The electrical pin configuration of the balanced DB 25 input and output sockets comply with the TASCAM standard (see graphic below). The nominal input level is +4 dB, other levels are transmitted 1:1.
DB 25 to XLR, TRS or RCA multicore cables are required for connection of input and output signals. The eight channels of the DB 25 connector at one side are routed to eight single XLR, TRS or RCA connectors on the other side.

The channel configuration is free (input=output). Here are some common multi-channel configurations:
SMPTE/ITU: L/R/C/LFE/LS/RS/L(t/o)/R(t/0)
DTS: L/R/LS/RS/C/LFE/L(t/o)/R(t/0)
Film: L/LS/C/RS/R/LFE/L(t/o)/R(t/0)
SDDS: L/LC/C/RC/R/LFE/LS/RS
