TOPIC:

Have this puppy stored in a closet the last 8 years or so and recently decided to set up a 2.1 channel system with an old Sonos Connect Amp (has 2 RCA outs, 2 speaker terminals, and a subwoofer out) along with a couple passive speakers and a powered sub (with XLR).

I want to run a 100 hz low/high pass for the subwoofer and speakers.  But am a bit lost on how to connect the MiniDSP here.  Would I basically connect an RCA to phoenix adaptor cable from the L/R RCA outs to the MiniDSP input 1 ... like these:

www.amazon.ca/Connector-Speaker-Adapter-...s%2C100&sr=8-40&th=1

Then one of the 4 outputs to the subwoofer with a Phoenix to XLR cable that came with the unit.

But how do I connect the passive speakers in this setup?


 

This is the back of the Sonos Amp, it only has Audio In, so am confused, maybe I can not use the MiniDSP to put a highpass on the speakers?

@PBC

If you're trying to do a 2.1 with the Sonos, you'd have :
Source (Sonos ) - > DSP - > External amplifier for your main L&R + Analog out to your subs. 

You can't use the onboard amp for your main in this case. Makes sense? 

An option if you don't have an external amplifier (other than Sonos) would be to use the Sub out from the Sonos only for tuning the Sub via the miniDSP platform. That's an option here. 

Makes sense?
