DB25 Cabling and connection information

For all our products we use the ANALOG DB25 D-sub Tascam standard.
One DB25 cable holds 2 stereo inserts (2x stereo send, 2x stereo return), so for 8 inserts you will need 4x DB25 cables.

There are various standards for DB25 D-sub cables, but the pinout and channel configuration is the exact same for all standards. The difference is that the channels vs sends/returns will be different. The analog DB25 tascam standard which we use, has the send/return swapped compared to the digital version.


This is the correct channel and send/return schematic:

Insert 1:
channel 1 - insert 1 - left send (male XLR)
channel 2 - insert 1 - right send (male XLR)
channel 5 - insert 1 - left return (female XLR)
channel 6 - insert 1 - right return (female XLR)

Insert 2:
channel 3 - insert 2 - left send (male XLR)
channel 4 - insert 2 - right send (male XLR)
channel 7 - insert 2 - left return (female XLR)
channel 8 - insert 2 - right return (female XLR)
