Pro Audio Support

Q:
When recording or monitoring from the RCA analog out of the Audiomedia III Card, you can hear electrical pulses through the monitoring system each time the drive head accesses the drive.
 
A:
Internal grounding problem with CPU and/or SCSI/ATA bus.Power, SCSI and Audio cables should not run parallel with one anther. Either isolate the cables from one another or have them cross at right angles to minimize/eliminate inductance between cables. The same goes for a wall plug that could have a unconnected ground pin. You can buy a $5 device that will tell you whether your wall socket is properly grounded or not.
