Good afternoon all
So I got this cheap HDMI 7.1 audio extractor (aprox. 50$) off ebay or aliexpress (can't quite remember). Usually these kind of products either miss a bunch of specs or stated specs are a blatant lie. So I decided to try some measuring myself. Be warned though - I am no expert, more like a total noob.
My intended use for this thing was a cheap gateway into multiway active speaker building. Started out with my Yamaha AVR's HDMI input and EQAPO, but never got comfortable with the idea of the AVR internal DSP and circuits messing with things, so I got this audio extractor. Still using the AVR, but with analog multi channel inputs.
Mostly I was interrested in voltage on max output and noise floor - no high expectations.
Here it is:
Running REW with Java drivers (EXCL?) as Asio wont work. Capture device is Behringer UMC204HD TRS insert to bypass preamps.
Noise floor with no connection on input(forgot to close settings window, so there is a little spike at 18kHz not seen):
HDMI extractor connected, no signal:
