Western Electric 630A Omnidirectional Dynamic Microphone
This wonderful looking mic is a Western Electric 630A Omnidirectional Dynamic Microphone. Also known as an Apple & Biscuit, Ball & Biscuit, and Eight (8) Ball. They were also sold in the UK by STC (Standard Telephone & Cable) as model 4021.
Western Electric (U.S.A) developed this dynamic mic in the late 1930s. It’s omnidirectional to 15 kHz when used vertically, and semi-directional when used horizontally.
The microphone head is sold on its own but we also have the 4069A Cable and Plug, terminated with a Cannon XLR connector, available to purchase in a separate listing.
In good cosmetic and working condition, with a few surface scuffs/blemishes commensurate with age and use.
Pricing for the variations is as follows:
630A Microphone head only:- £220
4069A Plug and Cable only (separate listing): £90
The 630A microphone design has been much venerated for the high quality of the instrument, and its reliable performance in studio work and acoustical measurements. It was used as the main Talk-back microphone by the BBC from the 1950s until the late-80s!
For illustrative purposes, I’ve included some images of the microphone with the connector, and an original 1940s advert for the 630A. The connector and advert are not included in this sale.
Approximate Microphone Dimensions:
Face Diameter: 6.4cm
Height (Microphone Head only): 6cm
A bit of glam and history for your shack or lounge!
