I had an integrator call today asking what the compatible pin outs of the QTP-DB25 adapters were .
QTP-DB25M and QTP-DB25M use the Tascam DB25 Pinout.
Channels 1-4 terminate to one RJ45 and 5-8 to the other.
If you are using AES in and out the pin out is identical.
CH 1-4 are IN 1-4 and CH 5-8 are OUTPUT 5-8
The Third Compatible pin out is the Yamaha AES pin out. The QTP-DB25Y is only available in a male DB25 connector. The IN the first RJ45 and OUT the second.
All the RJ 45 connectors terminate to the TIA -B standard and use the following pair and polarity designation
I know you’re curious about what QTP costs, There is a new button on the menu!
