Kids:


I have a client with an off-grid recording studio, probably the worst case 
situation for buzz problems to occur.  The Heart Interface created an 
untenable buzz.  We tested with battery powered equipment and found the 
buzz was emitted from the Romex in the studio and received on the guitar 
pickups, which are great antennas.  We had an SW on site with a feeder 
running right next to the studio.  We installed a transfer switch to use SW 
power while recording.  That helped substantially.  When the Heart died we 
installed a Stat Power and it was the quietest of all.
