The Classic Dick Swettenham Olympic Studios Design
Originally designed for the Olympic Studios' console by Dick Swettenham with guidance from engineer Keith Grant, this equalizer is a very useful toolbox. It is the sound of records made at Olympic studios in the 60s and 70s and is now available in a 500 series format package.
The 9052 provides extremely musical high and low shelving bands, two mid / low frequency bands of equalization as well as a two position high-pass filter. The equalization points chosen provide instant control over musical timbre.
An addition to the original three transistor makeup gain stage is a class-A transistor output stage which will drive the most demanding of loads. Also included is a step-down input transformer and step-up output transformer which provides 6 dB greater headroom than the 500 series voltage rails would normally allow. (Note the output level specification below.)
