The Mastering Room
Marsh Mastering's Main studio features a purpose-built hybrid tube/discrete console, developed in-house with Steve Firlotte of Inward Connections with custom and modified processing from EAR, GML, Maselec, A-Designs,
TK Audio, SPL, and Inward Connections. The console is capable of operating in both Left/Right and Mid/Side configurations simultaneously. Console tubes are hand-selected Telefunkens and our elliptical and M/S networks are one-of-a-kind designs from Steve. We've taken a fanatical approach to signal flow integrity and the results speak for themselves.
The Lathe Room
Marsh Mastering's second studio is The Lathe Room. Centering on a vintage Scully 601 Disk Mastering Lathe with custom wound Westrex 3DII stereo cutterheads, a vintage Westrex 2B Mono cutterhead and a custom modifed Westrex amplifer rack. The entire system has been restored under the knowledagable eye of local Scully/Westrex 'Godfather' Len Horowitz from History of Recorded Sound.
The Lathe Room has it's own custom analog mastering chain with EAR tube EQ, Maselec A/B program EQ's, Maselec compression & HF limiting, custom HP/LP filtering by GOLY and a custom cutting console by Inward Connections. Mastering live to the lathe from analog tape is accomplished through a pair of Studer A80 tape machines with 1/4" and 1/2" configurations allowing for 100% analog mastering tape to disk.
