I currently have a 5.1 music setup that goes from Roon via a small fanless PC to an older Denon (1612, don't judge) with "plain/bad Audessy" via HDMI.
For budgetary reasons I'm stuck with the Denon for now, it's otherwise fine for my needs - but I wondered if I could use Roon's digital DSP to bypass all the AVR's processing. Seems like it should be totally possible, and potentially be higher quality than the AVR's internal processing, given how well Roon's digital DSP seems to work.
There are already good walkthroughs for using REW and such to do room correction with Roon's DSP filters, which I'm not asking about because that's fairly straightforward/well-documented.
The question I'm asking is this - is there any downside to doing my sub crossover from within Roon's DSP and bypassing the internal AVR digital crossover, versus letting the AVR's internal processing do it?
I've currently managed to do this in Roon's DSP engine with a combination of
- the Speaker Setup processor (to duplicate the outputs of all speakers to the LFE channel)
- a High-pass filter @80hz with a 12db slope via the Procedural EQ processor, applied to all channels except LFE
- a Low-pass filter @80hz with a 24db slope via the Procedural EQ processor, applied to the LFE channel only
This seems to work pretty well honestly and from what I can tell more or less equates to what Audessy/the AVR crossover would do internally - but I'm looking for someone smarter than me to validate what I'm doing here and tell me if I'm being extremely thickheaded or missing something, or if there are downsides to this approach that I'm missing.
