Integrity Music needed to add an editing suite to their existing recording studio in Mobile, Alabama and at the same time wanted to “clean-up” some power quality issues. Puckett Engineering’s solutions began with an evaluation of power conditioning technologies to address their power quality issues. A rotary (motor-generator) type power conditioner was recommended. The rotary power conditioner was a perfect fit given the power quality issues, such as voltage sags. In addition, because the power conditioner provides 100 percent electrical isolation from the utility, this eliminates lightning surges, noise, voltage distortion, and other potential power quality issues from reaching the sensitive audio equipment.
