I know the M-Scaler colours are super confusing but I’m not sure what you’re referring to.the tt2 is set to dbnc
the input on the chord mscaler is a bit confusing as I understand the instructions since why is there a pink auto mode and a dbnc mode .....I guess I am safe on the pink mode although technically if using the tt2 it should be in blue mode (as my optical cable is in the digital 2 input of the mscaler)
I am also confused about the hms output sample rate chart (4.5) in the mscaler manutal as it shows max upscaling from the Oppo 105 is 192 yet the readout on the TT2 shows 768 in pink mode and 705 in blue mode.
does this mean I can only use usb input on the mscaler to get to 705 or 768?
First of all, the left most button is the video mode button. I usually leave it off (no color) so that I get maximum 1 million tap upsampling. If I’m watching a video and need less delay, I usually manually switch to white mode so that I get 600,000 taps. I dont use the automatic mode because the auto detection is based on sample rate (since M-Scaler has no way of knowing if you’re watching a video or not). So if it’s 44.1kHz, it’s 1 million taps and 48kHz it’s 600,000 taps and I haven’t tried 96kHz, etc. But I sometimes watch videos with 44.1kHz sound and listen to music with 48kHz sample rate.
The second left most button is the source input selector. Pink (magenta) is auto select mode which I never use because I find sometimes other sources can be active without me knowing so it’s impossible for M-Scaler to read my mind as to which source I want. I have two optical sources so I choose between one or the other (green/blue). The reason why there is a light blue/cyan mode for dual BNC input is that some sources would feed 192kHz signal via dual BNC. It’s a fairly specialized scenario so the option is there but I don’t think anyone actually uses it. In fact, since I don’t even have BNC’s plugged into M-Scaler, the dual BNC input mode is not an option for me.
The third left most button is always on White because I want maximum upsampling. I never touch it.
Oppo 105 doesn’t upscale if you’re connecting it Toslink/S/PDIF to M-Scaler. And most Blu-rays are copy-protected so you won’t get anything more than 48kHz out of the Oppo 105 via Toslink/S/PDIF. If you have high-res music files on a USB stick plugged into the Oppo, then you can get that file played back via Toslink/S/PDIF at the original sample rate, e.g. 96kHz or maybe even 192kHz.
And this leads to the fourth button from the left (third from the right) which should be set to off and when there is music playing the color of the button tells you what sample rate the Oppo is feeding your source music at. Red is 44.1kHz. Orange-Red is 48kHz, yellow is 88.2kHz, green is 96kHz, blue is 176.kHz and purple is 196kHz.
So going back to your question about why in pink/magenta auto mode, you’re getting 768kHz on your TT2 and in blue mode you’re getting 705.6kHz, my suspicion is that either in pink mode, you’re running a different source (or the same source) that’s feeding 48/96/192kHz to M-Scaler and in Blue mode, your source is feeding 44/88/176kHz to M-Scaler so the upsampling goes to the appropriate 16fs frequency. You can figure this out by looking at the color of that 4th from the left; 3rd from the right button color when playing music.
