Title: How does QTP work with studio hub?
Post by: APKaudio on April 24, 2015, 05:48:17 PM
Someone at NAB asked a great question:

"How does QTP hook up to Studio Hub?"

The answer is "perfectly" with a few Q-mandments broken.   But we're able to work though that as Engineers. 

Studio hub uses a pin out of
1 Left +
2 Left -     
3 Right +
6 Right -

These are Sun and Earth pairs.   

Where QTP follows the even pins to the +ve.  To integrate SH, it needs a polarity inverse and abandonment of 2 pairs.

All QTP patch cables can have this reversal at no extra cost. 

QTP takes its inspiration from the AES14 Standard (1992)  http://www.aes.org/publications/standards/search.cfm?docID=19 (http://www.aes.org/publications/standards/search.cfm?docID=19)
