The dspMusikLCD uses the ADSP21479 DSP and only has HiRez DAC outputs. No digital data outputs.
If the M2 digital crossover is published, I can look at the design. Of not Clayton would have to ok it.
Rich, the above posts are not asking about using dspMusikLCD as a crossover for the Spatial Audio M2 (Clayton Shaw). They are asking about using it in place of the Crown DCI series amps, iTech series amps, the BSS London sound processors, or the new Inonato controller to act as the active crossover for the JBL M2 studio monitors. The JBLs require crossovers and filtering preprogrammed by JBL and uploaded into any of the above Harman group electronics to run.
I mentioned this in passing in the JBL M2 thread elsewhere on AC in that maybe your solution would offer a "better" audiophile solution to the active crossover solution for the JBL M2 than the OEM solutions, either through a "better" DAC section in the dspMusik and or providing a "higher quality" option than a miniDSP (aftermarket) or BSS (OEM) outboard DSP/crossover to allow the use of various non-Crown (or not Mark Levinson) amps with the JBL M2. As an example, one notable consistent gripe from prospective "audiophile" JBL M2 buyers is the fan noise from the Crown/iTech amps if they are placed in the listening room with the speakers rather than an outside electronics closet.
JBL (for obvious reasons) has not nor will likely plainly publish in plain text the settings contained in the configuration files for the JBL M2 that would be loaded into their electronics as they (for a lot of reasons) wish to sell the JBL M2 as a complete, proprietary, and fully integrated system. However, a little digging around the Internet would get one a pretty complete picture of the settings required to implement the crossover taken from data collected by various owners of the Harman electronics who have discussed the settings online.
For what it is worth and for sake of reference, regarding JBL's evolved stance on the DIY market and the JBL M2, the street price of the D2 compression driver mysteriously went from $300 to $2000 overnight and rumor on the Internet suggests that ordering from JBL as a service part now requires a M2 serial number. Again, for what should be obvious reasons, JBL has seemingly been trying to close loopholes that were benign and practically very helpful in supporting the professional sound community/industry in regards to information sharing and parts availability, but have kind of taken on a (from a business perspective) monstrous life of their own in the hands of DIY audio hobbyists.
I don't have a dog in the fight, but as I might have suggested in the other JBL M2 thread, it might be worthwhile to some to pair the JBL M2 speaker system with (comparatively) cost no object electronics outside of the Harman group ecosystem.
Slightly aside, frankly, I'm kind of surprised that no one (in the pro side of things or the audio hobbyists) has yet invested the time and effort into taking apart the LSR 705/708i and fully developing the passive crossover in it, or developing completely a passive crossover for the JBL M2. Just to head off concerned parties at the pass, yes, I'm fully aware that this action directly defeats the whole purpose of the fully active system as packaged and sold by Harman, is so far out of anything serviceable as a warranty issue as to be laughable, and opens a continuously heated debate about "performance". However, much like the completely DIY builds of the JBL M2 speakers themselves, all of those arguments or debates completely miss the point of such an endeavor just as much as doing so completely misses the point of accepting the system at face value as advertised.
