I’ve a wee problem with my M Scaler and DAVE, Before I conclude that it is a fault and not a misunderstanding can any of you guys help me in trying to replicate the issue? The problem is to do with the various output Sample Rates, and how they show on the DAVE,
With either USB or optical 1 input to my M Scaler and both BNC leads connected to BNC 1 and 2
If I play a 44.1 sample rate track
.. and set the OP SR on the MScaler to Red (bypass) my DAVE shows 44.1kHz Red OK So far so good.
.. and set the OP SR on the MScaler to Green my DAVE shows 88.2 kHz Yellow.
.. and set the OP SR on the MScaler to Blue my DAVE shows 176.4 Light Boue
.. and set the OP SR on the MScaler to White my DAVE first shows 352.8 kHz Blue, and the sound is mono, then a second later there is a little “tick” and the DAVE flips to 705.6kHz which is what it should be.
So cycling through the Output SRs on the MScaler gives me 44.1/88.2/176.4/352.8 mono briefly/705.6
The table in the manual (as far as it is intelligible) suggests the progressions should be 44.1/176.4/352.8/705.6 - ie no 88.2 step. (and no brief mono interlude).
Even weirder things happen with a 96khz input .. cycling OP SR then gives 96/96/192/384 mono changing to 768 after a click.
Doesn’t matter whether I use optical or USB input, or which BNC ins on the DAVE. Drivers are latest, players are JRiver (wasapi exclusive) or Qobuz or a Squeezebox Touch for optical. All these give expected sample rates if I connect them straight to the DAVE so I trust the source.
Is it just that Table 4.5 in the M Scaler manual is a lot of tosh, or is either my DAVE or M Scaler wonky?
So could anyone who has an M Scaler / DAVE and 5 minutes spare play a 44.1 track and cycle through the OP SRs on their M Scaler and see what the DAVE says?
Incidentally for all OP SRs apart from the 705/768 it makes no difference whether I have one or two BNCs connected.
