Quoted from radial_head:I've tried the white north, an amazon generic buck boost, and a separate power supply. The white north and the generic buck boost completely sent my Rocky and Bullwinkle into a frenzy. Mpu went nuts. All sorts of chaos. On my Baywatch, they white north worked somewhat, the amazon one worked then sent the sound board into a complete tizzy (began making jumbled noises).
The isolated power supply worked best. I tap into the DBA harness power wiring, and run a new connector up the backbox through the wiring harness tube. Worked on both. Dead silent, and didn't interrupt the DBA wiring harness.
Hi and hope all is well on your end. You wouldn't by chance have any pictures of the power supply ( or where you got it) and how you tapped into the "DBA" ( not really sure what that is). I'd love to knock out the noise on my Checkpoint.
All the best,
Robert
