New Functional Innovations Introduced by Hidley for Control Room and Studio Acoustic Improvements

1965 
1) 40 Hz Dual woofer control room monitor developed and installed.
2) Drum kit and bass guitar platforms «isolated»from the studio floor structure using coil spring suspension.

1967 
3) Built and put into commercial operation the first 16 track 2" tape recorder.

1974 
15) Introduced and installed sliding glass door systems into the control room/studio divider wall.

1978 
16) First «Rock/Stone Room» (Phil Newell`s concept).

1982 
17) Console recessed flush with control room floor (no obstruction between monitor and engineer)

1983 
18) Developed the concept and built the first «non environment» control room.
19) 30 Hz linear Kinoshita monitoring to control room installed and operational.
