I think I found the solution! mine is completely silent now! I had an output RCA on a channel from my sd player with a cable to XLR and had 2 pins Bridge on the XLR and that in he sq5. it turns out that the mixer can’t handle that and this is the solution
Was the RCA to XLR on an input on the SQ or on an output.
Using it on an input you would tie XLR pin3 to pin 1 ground, using it on an output
you would only connect to XLR pins 1 for ground and Pin 2+ for the tip of the RCA.
Ideally you should be using a transformer or an active isolation / balanced to unbalanced
conversion between the RCA and the mixer.
I have another question! , we are tape artists, and often plug into other mixers for a new act, but several colleagues have already plugged into another mixer, now they accidentally had Phantom power turned on, and yes then you blow the sq5’s output! how can you prevent this “secure”
You need to use transformer isolation be the output of your mixer and the input to another mixer….unless you are fully in control of the mixer you are connecting to and keep the phantom power off on the input.
Something like this……https://www.radialeng.com/product/twin-iso
The transformer will block phantom power.
