Hi,
I recently purchased a used Mixing Link and I’m having an issue with headroom. I’m experiencing clipping/distortion in the output signal well below the input peak level, right around when the -20 dB light comes on. Input signal is trombone/trumpet played into a condenser mic with phantom power on into the XLR input on the Mixing Link. Distortion is present in the DI/LINE output as well as the headphone output, so it seems to be occuring at the pre-amp itself.
The unit is still usable, but since I’m unable to put much gain on the Mixing Link preamp, I have to use more gain on the mixer/audio interface, which of course boosts the noise from the DI output itself to excessive levels.
My only thought for what might be causing this is the power supply. I bought the unit used with no power supply, so I’ve been powering it with a OneSpot daisy chain. The OneSpot is 9V with a max output of 1700 mA, and the Mixing Link draws 500 mA at most, so it should be fine, but I’ve had other pedals (specifically compressors) that give a different amount of headroom depending on the power supply.
Anyone experience anything like this?
