EMI 920 modules


Manufactured by EMI England Hayes Middlesex circa 1967.


EMI Electronics Ltd Broadcast & Recording Equipment Divison; Hayes, Middlesex, England (UK) - also called:  EMI Electric+Musical Industries Ltd.


The modules were the EMI stereo mastering equalisers produced in the UK, with several made and shipped with the REDD51 consoles, to many parts of the world as outboard equalisers for the consoles. The 920 modules were part of the REDD series module designs which included the 806 mic preamp and others.


EMI's REDD  recording consoles had a single bass and treble “pop”

equalizer per channel — a 100Hz shelf, 500Hz and 10kHz boost/cut,

the latter providing similar, if limited, curves to what a Pultec EQ can do with its separate boost and cut controls at the bass and treble ends of the audio spectrum. There was also an optional, fixed bass lift on each mic channel and specialized outboard EQs for additional frequencies. As the internal EQ was limited the external modules filled any gaps and were used extensively with the EMI sessions of the 50’s and 60’s..  


The History of my two 920 modules


To date the pair that I own are the only known pair of these modules in existence apart from the pair I sold on Ebay many years ago, I have only these two modules left for sale. These modules are built in EMI Electronics colour "EMI green" as used in all professional studio gear built in the 50”s and 60’s. A circuit diagram is included in the sale.


These modules were used as a plug in equaliser module for  stereo mastering,

My modules were used in the EMI Studio's  in Castlereagh St Australia in early studio 301 days. When the original studio's were closed the studio's were fully refurbished with new TG12345 consoles and other gear, during the studio refurbishment these modules were thrown out as junk,  and rescued by the original owners of Soundwarp studio's in Pitwater road Brookvale NSW and used for disk, tape, and CD mastering for many Australian record companies, until the business was sold.


In 1995 new owners took over the business, Merideth Brooks and Bill Syratt, Merideth having for some 20 years worked for CBS mastering pressings for them, and Sony music (incorporating EMI) using these same pair of modules. The vintage Sony records cardboard box they came in when I purchased them, is also provided for interest.

Serial numbers are H134 and H146
