This is a restoration of the RCA model 50-A (MI-4030-A/B/C/D/E) microphone manual from 1934.  This is not an old original manual. 

See my eBay store (click in the heading area above/right) to see the individual listings for the many restored RCA microphone manuals and documents available. The top category is Microphone Manuals.

Did you know that several companies now offer restoration and repair services for these mics? See the links on my eBay "about ME" page for more information. We offer fine quality protective "bags" for the 44, 74, and 77 series RCA mics, along with manuals, refrigerator magnets, T-shirts and restored RCA ads for the vintage microphones. See my eBay store (click in the heading area above on the left) to see the individual listings for the many restored RCA microphone manuals and documents available. The top category is Microphone Manuals.

The time-consuming restoration process involves carefully scanning the original manual into Adobe Photoshop and spending hours processing each page to produce a manual that looks better-than-new. All photos are stripped out and processed separately. All tears, marks, stains, etc. are removed from the original manual, even printing defects are corrected. The text is brought back to original sharpness and detail, as are all of the illustrations.

Our production standards are high: 

  • Each manual is individually printed in the USA. 
  • We use heavy stock paper for the front and back covers, and
  • 32 lb. laser paper for the inside black & white pages and
  • heavy laser paper for any page with color
  • If the original RCA Manual had a blank page, so will ours!
  • 10-mil thick clear plastic sheets protect the front & back covers.
  • Everything is then bound with a plastic ring comb, so that the manual will open flat and be very durable.

This is a highly professional product that takes a lot of time to prepare, but it is worth it! eBay customer feedback has been very positive regarding quality. So, if you own one of these wonderful RCA microphones, you deserve a quality manual to go with it.

This manual contains photos of the microphone, and gives detailed descriptions and specifications of the microphone's performance. There is also a detailed parts and accessories list, as well as a detailed wiring diagram. Also included is a four-section page of orchestra miking layouts. This information is invaluable in using vintage RCA microphones to best effect. Most of the original manuals have been lost. Now you can have something even better!
