The best way to think about the DSP in the PMA amps is that it is the best adjusted crossover you ever heard. The guys go to great lengths to get things voiced the way they want and over the course of many measurement sessions on behalf of our dealers, I have gained enormous respect for the absolute consistency in performance across the range. I use them as a training example since they really do act as close to an ideal speaker as anything I have worked with and all of the good theory about boundary gain and so is clear to see and quick to correct.
I have always found the cross over to be perfectly implemented and since there are additional benefits such as soft limiters built in to the DSP I cant think why I would bypass them.
When working with the Dirac system the key thing is to make sure that you are not artificially boosting the HF which is the mistake I am fairly sure that most make when setting up the RS20i (see that particular thread). Close mic checking is your friend to ensure that it all stays flat as designed.
When working with Trinnov I always found it a bear to handle the channel routing with multiple surrounds and such. I suspect this is a lot easier when using the higher channel count units but I have never personally used higher than TEQ (although we have a system with dual units from when they were first released). Ignoring that, there is no doubt that the coherence of the sound field is impressive and I would be interested to test with a 9.1 or even 13.1 sound field coupled to proper decoding.
So to sum up, PRO are my favourite cinema speakers by a mile. I love the guys and I love how easy it is to work with the product. Even the small units like the 8s give astonishing dynamics but my personal goal in life is to have a system with 2215s and the 24" subs installed in my own home. It is hard to make them sound bad and using the PMA alone results in a clear and effortless sound.
I personally get better results when using the RS20i and Dirac but this is by no means an automated process IMO. God bless the Room EQ Wizard is all I'll say. Very easy when working with large channel counts.
Trinnov is a great product and Curt has helped me a few times but for me it is an accessory to other decoding processes rather than a stand alone solution if you are looking for the best overall result. I truly think that the combination of an RS20i front end (or even better and AP24 with Auro 3D) going digital in to a large Trinnov would be an outstanding solution but not for the faint hearted. In that scenario I would probably let the Trinnov do EQ as well for ease but would still have to get the normal tools out to check everything!
The PHC speakers are far more sophisticated and polished versions of my own (relatively crude) pro audio compression driver speakers. I think they will be a perfect upgrade for me. I am ready to move on from my first gen QSC DSPs and really bring things up to state of the art in my room. THey are near the top of my list right now. I'd like to get this project completed in the next couple of months.
I have weighed the RS-20i but budget constraints and taking on two very sophisticated pieces of equipment at once (and Trinnov MC), would likely ruin my fun. I am going to go Trinnov and, if need be and after I have squeaked every last bit of juice out of the Trinnov piece I am still unsatisfied, then I may consider the RS-20i... And truthfully, the RS-20i thread with the myriad of set up issues and the still evolving firmware, remind me of a cause I am not ready to crusade for. In my younger days, yes but as I get older, I find my time more valuable.
Considering the amplification, I am not sure if the DSPs in the PHC amplifiers can be completely bypassed? Perhaps in some channels, I would like to bypass them fully and let the Trinnov do such duties. THe goal here is as much of a full digital path as possible. IN the side fronts, 2 sets of sides and rears, I amy employ the PHC amp digital filters / crossover, etc but maybe not up front. I am speccing out SCR-15s for LCRs and SCR-12s for side fronts, and SCRS-12ai for two 2 sets of sides and pair of rears. So far, I am planning on an 11.2 set up but am getting some consultation as to whether this is feasible given the physical constraints of my room. I"ve talked to Curt H and I really appreciate his expertise and complete understanding of all things dynamic HT and Trinnov.
I may consider other amplifiers for my LCRs or all speakers (e.g. ATI, Bryston or others that may be recommended). Each speaker is bi-amped so I'll require quite a bit of amplification. If the DSPs built into the PHC amps cannot be bypassed, I will likely amplify them with one of the aforementioned brands.
Can these amps' DSPs be bypassed (and avoid the extra A/D and D/A)? Thanks!
