Hello!
I have a big problem with the audio on my mixers. It makes static noise, out of nowhere. Let me explain.
I have those 2 mixers, QU-24 and QU-SB. The QU-24 mixer, i use it for main elements, such as the microphones for the person who speak, for actual audio speakers, and to broadcast the audio through a PC for OBS. All good so far. And the QU-SB i use it for microphones to sing, instrumentals, and portable speakers. And sometimes, I get the audio form the SB and link it to the QU-24, to stream the audio that is playing on the SB, to the Qu-24. It was all working just fine, with no issues. But suddendly, I started to make really loud static noise.
First I thought it’s the cable, and I changed it. The problem still occurs. I’ve tried some headphones, and a speaker directly to the output port on the SB, and the problem is gone. I’ve tested my phone, to play something on the QU-24, the audio is ok. But when I connect the 2 mixers together… Static noise…
As I change the lenght of the cable, the problem fades away. But it’s still there. I’ve tried different adapters, a straight cable… The mono and stereo jack, individually… It’s still there. I even bought a DI unit, and the problem stil persist.
The way I linked my two mixeres, was through the headphones out port on the SB mixer. And the input ST2 on QU-24. Ain’t the best way, I know. But now, every out port does this.
Any idea what could it be and how I can fix it? Or how I should troubleshoot it? Cause I tried almost everything, and nothing.
