Did Shure ever make an OEM microphone for RCA?FAQ #5498
Question:Did Shure ever make an OEM (Original Equipment Manufacturer) microphone for RCA?
Yes. Around 1940, Shure provided a Model 399 crystal microphone to RCA. It was likely an accessory for RCA two-way radio equipment.
The Model 399 was based on the Shure Model 708S – a crystal "Stratoliner" microphone supplied with the S36 desk stand. On the S36 front, an RCA logo metal button replaced the Shure logo button.
