Title: Weird noise from all outputs.
Post by: MarconeMusic on March 07, 2022, 07:53:13 PM

Hey all.

Just got to the studio and found an odd noise over all group outputs.
Patching in to pre vca gives me clean signal out.

If I patch a dead cable in to the multitrack sends it “breaks” the noise.

But it’s over every channel output. 

We also had one of our audio amplifiers die on one Channel the same day.
Nothing powered down tho. Which is odd. We have a lot of trip wires for power to not boot back up if that happens. Which it didn’t.

Here’s a link to the noise. Audio files. Plus a pic of the psu delivery voltages.

Fyi it’s very low level. But not normal.

False alarm. 
We installed a sansamp in the producer rack and unplugging it stopped the noise.
