Los Angeles, CA (September 8, 2017)—Marsh Mastering in Los Angeles has recently undertaken a series of quadrophonic remastering projects for artists as diverse as Alice Cooper, Judy Collins and Sly and the Family Stone with the help of PMC monitors.

Stephen Marsh, who owns the facility, has been remastering the original quadrophonic tapes and transforming them into high resolution multichannel mixes in SACD surround sound. He has also been remastering original two-channel stereo mixes for SACD and CD.

“With these old tapes, it’s like listening through a time machine so it is vital that I can hear every nuance of the original sound,” Marsh explains. “The PMC monitors have proved invaluable because they allow me to understand exactly what I'm hearing and I can therefore make quick, effective decisions that are both musically appropriate and technically sound.”

Marsh Mastering is equipped with custom modified tape machines and exceptional clocking and conversion, along with proprietary wiring feeding a custom monitor chain featuring Bryston-powered PMC IB1S main monitors and OB1 surrounds. The facility also has a PMC CB6 center speaker, which is added when needed.

Alongside PMC monitoring, Marsh Mastering’s technical facilities include a purpose-built hybrid tube/discrete console, which was developed in-house with Steve Firlotte of Inward Connections and features custom and modified processing from EAR, GML, Maselec, TK Audio, SPL, Elysia and Inward Connections.

“We've taken a fanatical approach to signal flow integrity and the results speak for themselves,” Marsh explains. “The console is capable of operating in both left/right and mid/side configurations simultaneously, while our console tubes are hand-selected Telefunkens and our elliptical and M/S networks are one-of-a-kind designs from Steve.”

Marsh’s re-issue credits also include albums by Bob Dylan, James Taylor, America, Yes, Nat King Cole, Eric Clapton, Neil Diamond, Crosby Stills & Nash, Heart, Bad Company, Dio, Bread, Phil Collins, Janis Joplin, Blood, Sweat & Tears, Earth Wind & Fire, Joe Walsh and Donny Hathaway.
