### ⭐⭐⭐⭐⭐ Review
*by T***Y on 26 November 2025*

I own a JDI duplex for my Neve DPA stereo mic preamplifier and I was getting buzz and hum from the keyboards I have connected to it. Once I added the Duplex the issues were gone and the sound was perfect. I recently purchased a JDI single channel to handle the hum I am getting from my TG Chandler Microphone Cassette Mic preamplifier, waiting to receive it and will leave yet another glowing review for this product.
