Technical issue for PSB alpha am3

[htlb]

Hello! Recently, I bought a pair of PSB Alpha AM3 speakers. However, when I use my computer as the audio source and connect the computer's USB port to the speakers' micro USB port, I found that the maximum resolution is only 16bit/48kHz, which is inconsistent with the 24bit/48kHz claimed by PSB. I tried different computer and cable, doesn't work. I also contact PSB, no response yet. I'm curious what the problem might be?

You have native 24/48 content?

Yes ,I,ve some 24/96 contents. When playing them by Foobar2000, if set output depth as 24, the system will report an error. Besides, there is no 24-bit option in the Format tab for the speakers either.
In fact, I found this guy has the same problem with me https://darko.audio/2021/02/psbs-alpha-am5-powered-loudspeakers-are-a-600-solution/ . As he said "Let’s begin with a technical issue. Using a Raspberry Pi 4 running Ropieee as a USB streamer, Roon automatically converted 24-bit data to 16-bit data before sending it on to the AM5 even though the AM5’s specifications state that the USB input can handle 24-bit/48kHz data.

 While PSB claims a 24-bit/192kHz limit for Toslink, I was only able to play 16-bit data without issue. When attempting to playback hi-res, 24-bit music via Toslink, the AM5 went silent and the status LED on the left AM5 would go into error mode, blinking red. Limiting data to 16-bit from the Toslink streamers to the AM5 using Roon’s Device Setup options solved the problem.

 As such, I was only able to review the AM5 streaming 16-bit data. Despite repeated requests for comment on this issue, my contact at PSB remained schtum."

24/96 is isn't 24/48. I'd assume it would have to be 24/48 for the speaker to handle without altering. I wouldn't worry about it in any case, 16/44.1 is perfectly adequate. More curious than anything.

I agree with you. 16/44.1 is more than enough for me. I'm just curious what happened, you know that "Curiosity killed the cat".

Found the 24 bit claim in reviews but not on PSB website... Did they change it after discovering the error?

Yes, it's the problem. I didn't find any official statement by PSB. All is review said "24 bit ... clamied by PSB". Possibly it was originally 16, not 24.
