REDD.47 Mic Amplifier
Microphone Preamplifier
From Chandler Limited:
Chandler Limited’s REDD.47 Mic Amplifier is a recreation of the original valve line amplifiers used in Abbey Road Studios’ heralded and rare EMI REDD.51 recording consoles circa 1959-1968.
Designed as a central component to the EMI REDD.51 recording console, the original REDD.47 line amplifier was used to amplify virtually every stage of the audio path (mic inputs, line inputs, echo sends and monitors).
The REDD.47 lent its unmistakably punchy, aggressive character to music recorded at Abbey Road Studios’ Studio Two between 1964 and 1968, including many tracks by The Beatles.
