Fully active for two weeks!
Not like exercise, been way too lazy.... But I mean my ZDT 3.5 style speakers.
Using my 2 in 8 out test box.
So how is it? Pretty awesome!!!
I fixed the reset issue with the PCM4202 ADC, as I am using Rev 1 boards I had to tack the wire on the DSP board. Would be easier with the newer boards, could just plug something in on those.
So it's not perfect, but at the moment I am begrudging disconnecting it to do more work, it does sound very good and with circa 200W to each speaker it plays damned loud,
Very happy so far.
I haven't measured the speakers with it. The passive crossover is emulated using whatever I could find in SigmaStudio to do the equivalent function.
I am getting an odd ticking type noise on a couple of tracks I keep playing. It's on the tweeter, maybe the mid-range. Not sure if it's the tracks or a problem with this setup. If it is this setup, I would assume an issue with the single TDM8 link I am using to drive 8 channels into the DAC with 1 ribbon cable. There are few settings under the ADAU1452 configuration for signal drive strengths.
I need to pull it out and do some proper scope measurements, which means I need to find my coiled ground springs for my scope probes so I can measure the signals cleanly.
Oh just one more song before that though...
