Leste en test av Denon AVR-X5200W, og der nevner de at den downsampler input signalet til 48Khz når romkorreksjon eller Atmos er aktivert.
Etter litt googling så har jeg funnet ut at dette gjelder de fleste receiverene på markedet. Er bare noen ganske få som klarer å kjøre korreksjonen i 96khz.
Da er den ganske bortkastet med 96/192khz materiale så lenge det blir downsamplet til 48Khz??

Utdrag fra testen;
I was a bit surprised to find the AVR-X5200W downsampling to 48kHz, thus limiting the high frequency bandwidth to just over 20kHz once the DSP was engaged. I confirmed with Denon that the receiver does this to conserve MIPS given all the processing power needed for Dolby Atmos and Audyssey. Audio purists will want to engageDirect mode for recordings with sampling rates higher than 48kHz as long as they don’t mind giving up Audyssey EQ and Atmos for purity of signal. Direct mode and Pure Direct mode will still allow you to enjoy the full resolution of Dolby TrueHD and DTS-HD with no downsampling.
