A bit of background. I recently changed my sublime (to me) 2-channel active setup. Bought new speakers and amp. Now, I had my heavily moded Klipsch with ScanSpeak 12mu midrange, instead of the horn, and TAD / Pioneer beryllium ribbon tweeters, left to upgrade my theater mains. Long story short, I put a passive crossover into these and hooked them up into my 7.2.2 Atmos setup in my Theater.
I decided to do some measurements without EQ in pure direct mode with no Sub.
I’m using MacBook Pro HDMI into Yamaha CX-A5100 processor to pure direct mode. Mic is about 6 meters away, so these are relatively loud measurements.
after doing some tests, I decided to test Airplay. Yamaha has a built in Airplay, it is Airplay 1. I also have an Apple TV 4K hooked up to my processor. So I decided to test both.
I was shocked at what I saw, what a shame. Measurements are done with 44.1khz, 48khz and 96khz sweeps. Very little difference with HDMI input. But with AirPlay, oh my.... Airplay 2 is a bit better, and 44.1khz signal performs better too, but still ridiculous frequency response. Also, distortion skyrockets for some reason.
now this cannot be a Yamaha issue as I have used Apple TV to stream the signal, which connects via hdmi. Is this what one would expect.?
Figure 1. frequency response with 44.1, 48, 96 kHz input signals. HDMI direct to processor vs Airplay 2 with Apple TV to HDMI input. Note worsening frequency response with 48khz and 96khz signals. HDMI is not really effected
Figure 2. Same graph with Airplay 1, streaming directly into Yamaha.
Figure 3. To clarify the picture, here is the HDMI input with 44.1, 48, 96 kHz signals on their own
I knew AirPlay is so so. I could not imagine it cuts out frequencies. Is this reality true or am I doing something wrong here? I really cannot explain this. It seems when playing the sweep, I can here the higher frequencies, but they do not register. ...or I am be I’m a bit deaf possibly.
BTW: These ScanPeak 12mu midrange woofers and Pioneer tweeters have some nicely low distortion. Klipsch woofers are no slouch either, producing relatively low distortion at extreme SPLs.
