TA5 to mini jack

[Jean Wallez]

How would you link those connectors to output R and L balanced signals from the Red TA5 to R and L unbalanced on mini stereo jack?

If the pinout chart I'm looking at is correct, connect the + wire from balanced channel 1 to the tip and the + wire from balanced channel 2 to the ring of the mini-jack. Connect the 2 - wires you have left over to the sleeve of the mini jack. Looks like one of the pins on the TA5 does not get used (no shield)

Why not just use the headphone out?

a note in the manual says that pin 2(ground) on the Rev A audio hardware was floating;not in Rev B.
I want to make a breakaway cable with 2 TA3 and 1 TA5(balanced return) to 2 XLR3 and 1 XLR5 for long distance but i want to connect also a SD 302 mixer and need a 5 pin to 3 pin adapter cable.

If pin 2 in Rev B is ground, connect it to the sleeve of the mini-jack along with the - wires. In your second post you say that you want to go from TA5 to 3 pin, so are you trying to interconnect TA5 to 3.5mm mini OR TA5 to XLR3?

The cable is TA5 to XLR5 with an adaptor cable on the mixer side XLR5 TO mini jack.

Are using the TA5 for monitoring? If you want really accurate output monitoring on the RED One I would take the audio embedded in the HDSDI audio and use a AJA or Blackmagic box to demux it. The analog audio outs are ok, but not nearly as accurate. You can hear "clipping" in the analog headphone/TA5 outputs at very high levels that is not represented in your R3D files. The digital audio out of the HDSDI is representative of what is recorded.

Good to know

found in wikipedia : "If balanced audio must be fed into an unbalanced connection the electronic design used for the balanced output stage must be known. In most cases the negative output can be tied to ground but in certain cases the negative output should be left disconnected."
what is the electronic design for the balanced output of the Red one?

 

[Alex Frausto]

If you have a ground connection (RevB), tie the - wire to ground and connect it to the sleeve of the 3.5 connector.

Come to think of it, I wonder if the revA board is not really balanced since it does not provide for a ground return and thus the - wire serves as signal ground.

Thank's.
