Hi @devteam

Does or will the SHD (www.minidsp.com/products/streaming-hd-series/shd) support the new Dirac Bass Control feature?

For calibrating crossover for up to 4 subwoofers independently? Using 4 analogue outputs with SHD.

Others have been asking largely the same question here:

www.minidsp.com/forum/dirac-series-suppo...ac-live-bass-control

I say largely as you're talking about 'up to' 4 subs which sounds impossible to me. For bass control to work it needs to handle the signal for the speakers that the subs are being integrated with, so you'd need two of the analogue outputs for left and right main speakers, leaving at most two for subs. Even then I wouldn't be holding your breath for this functionality to appear...

Generally with DACs, the balanced and unbalanced outputs are all active at the same time...

So why not run XLR balanced to power amps or active speakers - and have the 4 unbalanced outputs to 4 subs...

Doesn't seem impossible. Seems like a great candidate actually.

The balanced and unbalanced outputs on the SHD are active at the same time but they carry exactly the same signals (Output 1 Balanced = Output 1 Unbalanced etc). For bass control to work you'd need to send different signals to subs and main speakers.

I understand, that's why I've asked the question to miniDSP... it would need to be able to re-configure the outputs via Dirac Live setup.

The physical connections are all there to all it to work. So it would be a DSP/firmware thing... that only they can answer?

No. You're asking if a device with 4 independent output channels can perform a task that requires at least 6. It can't.

Two subs plus two main speakers is a question only miniDSP staff could tell you if they might be introducing DLBC support for.
