RMC-1L Digital Output for Subs?

[eris0xaa]

I was thinking of running dipole stereo subs on my Magnepan LRS+ from my RMC-1L.  Obviously I can tap the normal L/R channels and run into a miniDSP 2x4 HD, but why send the contents into the miniDSP for another generation of ADC conversion when it should already be available from the digital output?   Here are my thoughts on the pros/cons:

1. The digital output may not be available at the same time as the analog output.  I can't tell from the manual.

2. The digital output may only be available in a limited number of circumstances.

3. DIRAC correction is probably only available on the analog L/R channels.

4. Another round of ADC conversion probably isn't very noticeable at sub frequencies

Any ideas?

Thx

3 and 4, probably .... but most significantly, you won't get volume control on the digital outputs, and that's the deal-breaker.

But yes, I split my L/R and send one half to the fronts and the other half to a miniDSP (for DWM's in stereo, and subs summed to mono) and with the limited bandwidth being a tiny fraction of the sample rate I would not consider it a problem.
