Synapse

What an amazing little device! I’ve been using a JDS element DAC/AMP for quite some time and never had any issue with noise due to them being mains isolated. I have custom computer set up that has a massive GPU. When I added a subwoofer to my new studio monitors, I had this really annoying, hissing, popping, and static noise that was coming from my PC. I tried grounding directly to the wall outlet, bypassing the power strips to changing audio cables, and USB cables without any help. My usb cable was now bringing in the noise so to adding the sub.  I started doing some research Online and came across the JDS blog post about the new synapse product. Literally, there’s nothing else that I could find what can do what this thing does. As soon as I plugged it in my speakers had zero hiss, zero static and zero ground Loop noise. I actually thought my speakers were not on until I played some audio. The synapse even fixed the issue with higher sample rates not working in the past to my computer. Great job JDS making products that are much needed in the industry.

Whenever I would connect my DAC/AMP’s USB input to my computer, my active speakers would start buzzing. I put the Synapse in line with the USB connection, and it completely eliminated the buzz!

When switching to active monitors, the EMI from my high-end computer was audible and distracting. A lot of the most popular options out there for fixing this are either expensive (sometimes upwards of 100 dollars) or inconvenient as they require modified cables and separate connections for power. I decided on the JDS Labs Synapse because it was reasonably priced and very convenient, and after plugging it in all of that EMI noise was completely gone. No fuss whatsoever. If you're doing your hi-fi listening on a high end computer and are either trying to get every last drop of performance out of your setup or are expecting to use active monitors, I'd consider the Synapse a must-have!

Hi, The little tool seemed really promising to get rid of my headset static noise coming out of the computer (Poly Blackwire 5220 usb headset). When plugged in, I still can hear the noise, maybe a micro step down. I throw away the box too soon for a return. Don't do the same mistake! The package, the quality is great, all the cable to satisfy everyone.

Hello, I received my Synapse order and both are working well. Including in an environment with multiple PCs, router and streamers that generated noise in other gear. I like the form factor and subtle peek into the interior circuitry. Very nice. Scott
