The M1 box speaker ABC switch is operational. First using the original passive crossover for reference.

Will startup the logic box tomorrow to switch to the upgraded passive crossover for some run time. The crossovers are always getting signal from the amp channel they are connected to for extra run time.

Once that is running can then try the dspNexus 2/8 DSP crossover for the M1.

To have a fair comparison, each amp being used is getting signal from an AK4499EX DAC channel in the dspNexus 2/8 and pink noise will be used to check level matching. Each DAC channel has a digital attenuator with 0.1dB steps for matching.

Fun stuff!

The AB comparison is now setup for both the original and upgraded component passive crossovers.

All good, so waiting on the arrival of the other set of 4 XLR cables that match the first set of 4 to setup the dspNexus 2/8 as the DSP crossover instead of the passive crossovers for the C capability. The ABC switching just needs the 4 amps outputs to run the speakers.

Last set of 4 amp to speaker cables to connect the amps via the switches to direct drive the tweeter and woofer. This is for the dspNexus 2/8 channels to amps acting as the new DSP crossover to the M1 speakers tweeters and woofers.
