Latest from local BlackMagic support:
Yes the online Beta, aka with the latest release is to fix this bug.
A little explanation on what it will do. It will change the firmware toggling timing to be shorter, thus addressing the issue of not able to switch between DNxHD and Uncompressed.It should fix the problem which you are facing.
Do kindly try it out 😉 -
Have you tried the Beta 2 now available from the website?

Hi there, we are having exactly the same problem.
Were you able to fix it? If so, how?Local Blackmagic people have suggested the following, but we have not had a chance to try yet:
1) Downgrade the unit to 1.1.2 Firmware, Remove the USB 2.0 Cable and Power Cycle (off/on) the HyperDeck Studio.
2) Uninstall the 1.1.2 Firmware from the PC/Mac, restart the Mac and install the 2.0 Beta 1.
3) Plug in the USB 2.0 Cable, power-on the HyperDeck Studio, Open THe HyperDeck Utility and Flash the firmware to Beta2.0 firmware.
4) Once the update is finished, remove the USB 2.0 Cable, Power-cycle the HyperDeck Studio And reconnect the USB 2.0 Cable to the PC/Mac.
5) Now, Open the HyperDeck Utility, Select the Open Of DNxHD and try to capture again.
Does this work?

Tony, please read my post again.
I guarantee that the problem you are experiencing is because your mixer does not terminate Sleeve to Ring on the unbalanced 1/4″ inputs.
Apart from the “distortion” you describe, the other big clue is that they are using TRS connectors for inserts and almost certainly using the same component part for the line inputs.
You could “fix” the mixer by opening it up and soldering a wire between Sleeve and Ring (either on the socket or the PCB, whichever is easier).
Or you should use standard 1/4″ TS (mono) jack to jack cables (which obviously connect Sleeve and Ring by design).
I have to agree with you that Bobs posts have been somewhat misleading and unnecessarily sarcastic, patronizing and derogatory. This is why I posted my response to clarify the facts for you.
Glad to hear you are getting an Allen & Heath, the Zed 14 in particular is a good mixer and excellent value. -
Hello Tony,
The distortion you are experiencing is because you are only getting half the waveform (the positive half with respect to ground). The other half effectively becomes a square wave (which never sound nice).
A balanced signal consists of 3 wires:
1 – Ground (Sleeve on TRS)
2 – Positive signal with respect to ground (Tip on TRS)
3 – Negative signal with respect to ground (Ring on TRS)If you plug a balanced signal into an unbalanced input you will often only be terminating the Tip and the Sleeve (Ground & Positive with respect to ground).
What you need to do is connect a short link wire between the Ring and the Sleeve, effectively combining the negative signal with respect to ground, to ground.
Some unbalanced 1/4″ sockets mechanically connect Ring and Sleeve, but not all, sound like yours do not.
Bear in mind that this effectively “unbalances” your entire input cable so you lose all the common-mode rejection advantages of a balanced signal. Depending on the signal level, length of your cables and environment, this could be a real problem.
I suggest you get a better mixer that helps you keep everything balanced. A good quality, low cost mixer is the Allen & Heath Zed 14 which also has an internal USB audio interface. Great for getting audio in and out of your PC!
