15.9 Connector Pinouts 
D-Sub AES/EBU 
The D-sub connector provides four AES inputs and outputs. The pinout uses the widely spread 
Tascam scheme, which is also used by Digidesign.

The Yamaha pinout is quite popular as well. When building a D-sub to D-sub adapter or con-
nection cable, please make sure that the connectors are clearly labeled with Tascam and Ya-
maha. The cable can only be used when the Tascam side is connected to a Tascam connector, 
and the Yamaha side is connected to a Yamaha connector.
