What happens to a 24 bit PCM stream over Bluetooth?

Portable PA

Hello,

I am using an old, first generation 3-way Bose powered system, the one with the hockey puck desktop volume control. I see this has been discontinued. I have a USB connected DAC which supplies the signal to the 1/8" jack. The small speakers have started making a high pitched crackling noise at high volumes. The music plays fine, but the enclosure seems to have lost the structural integrity to withstand high volumes. Hence, I am thinking about an upgrade. (I also have a Wave radio, refurbished in 2019, and SoundSport earphones for my phone. I am getting ready to ship my retired Companion pair to my grand daughters. I have loved every Bose product I've used!)

 

I play quite a lot of 24 bit audio through my DAC, so I need to know how the PCM stream would be handled over Bluetooth. I read in the description of the S1 that it plays AAC streams over Bluetooth. What about 24bit PCM at sample rates of 88.2khz, 96khz and higher? Or, should I be looking at some other category instead of the PA systems?

 

Secondary question----can two L1s be paired for stereo over Bluetooth, like the S1s? 


Thanks in advance.

Hi Isaiah,

Welcome to the forum! Thank you for joining us.

I recommend using a wired connection for this - using Bluetooth is not suitable for playback of high quality lossless files. The S1 Pro uses an SBC Bluetooth codec, which does not support 24-bit high res audio. For more information, I recommend taking a look at this article.

Hope this helps!
