Topic: Totalmix "Centre" Phase cancellation
I have a HDSPe MADI FX with Windows 7 Professional. I am not new to TotalMix FX, but I have recently disconnected my AES monitor controller/DAC and MADI devices and I am now only using the Integrated TRS Line Out/Headphone output.
I have updated the drivers and flashed the hardware and I have re-read the user manual and made some adjustments to the DSP settings accordingly - I made the WDM Phones channel the only "Speaker" and set it as the default device in Windows/Sound.
Interestingly I resolved the apparent routimg issue at one point, but when I disconnected my headphones and connected another pair of stereo speakers via a TRS to 2x XLR cable, the problem returned and plugging the same headphones back in didn't reverse things back to function properly.
What I am seeing manifest is the stereoscopic information (the sum of the difference between L and R) is completely phase cancelled. I can only conclude that there are duplicates of the same signal that mustn't be panned hard L or R. This is supported by the fact that if I phase flip one side at a time on the main output, the centre information restores and only half of the duplicate signal reaches the main fader.
I've tried all kinds of routing configurations and reset all submixes various times etc.
I can't see activity on any channel other than the Phones Software Playback, which I have included in the Main Output submix.
I must be misunderstanding something fundamental here... there are no signals entering any hardware inputs.
Please help! Cheers
