Hello All,

I'm new to the forum and excited about my PreSonus Quantum. I recently upgraded from a Behringer UMC404HD that I was rather happy with but wanted to experiment with a lower latency device as I dive deeper in to the DAW realm of sims, etc.

My first step in trying out the new unit was to just playback some of my existing tracks. Generally, these are 12-16 channels with various delay, reverb and amp sims. A compressor on the master bus. These recordings performed fine on my UMC404HD at 128 or 64 samples. Generally though, when mixing I increase the buffer to 4096.

When I plugged up the Quantum, I started experiencing "static" for lack of a better term. I wouldn't normally associate this sound with "dropouts" and my CPU usage is minimal at this point. Anyway, I opened a ticket but still waiting on a response. I thought I'd post to this forum to see if anyone has had a similar issue and circumvent the ticket process.

Here are a couple of sound files:

I'm running a fairly capable mobile setup. 10750H processor with GPU, 16MB of memory. I have been running tests with the hardware monitors open and have rarely maxed beyond 35-40% CPU and less for memory.

I was thinking computer cables or the Tbolt adapter. My analog signal path is fine...as I said earlier, I get a steller output from my Behringer unit.

Hi Todd,

Did you end up getting it to work fine ? Could you solve the problem?
My Quantum is making that kind of constant "static" noise and it only does it at 44.1 and 48 kHz. I changed the Thunderbolt 3 cable and tried other things bus still keeps making this unbearable noise.
Any suggestions anyone????

This is probably related to C-States and CPU power saving features.

Which Version of Windows are you running?

PC #1: Asus Prime Z690-P, i5-12600k 10-core (6+4), 32GB DDR4 3200 MHz, RTX 3060 12GB, ADATA XPG 512GB M.2 NVMe SSD, 2 x 1TB WD Black HDD

PC #2: ASUS X299 Prime Deluxe II, i7-7820X 8c/16t, 16GB 2666 MHz DDR4, GTX 1060 3GB, Samsung 970 EVO NVMe M.2 SSD (Win10 Pro), Samsung 860 EVO SATA SSD (Win11 Pro), OWC Aura 512GB NVMe M.2, 2 x 1TB HDD

Mac: 2010 Mac Pro 6 core 3.33 GHz, 32GB 1333 MHz DDR3, AMD RX 5500 XT 8GB, Alpine Ridge Thunderbolt 3 Card, Aquantia 10Gbps AVB card, Dual eSATA PCIe + Stardom 8xHDD Raid Tower

Could it be that you have your pc, monitor speaker and audio interface in the same power outlet or power socket. Try to have all three in different power outlets.

Gigabyte Z490 VISION D
