Microphone Collection.

We’ve been making some changes at Agent Audio HQ recently, amongst them, updating our Microphone Collection.

The most recent additions to the collection are the Northern Electric 633A “Salt Shaker”, often badged under Altec or Western Electric, and the STC 4021c “Ball and Biscuit” or “Apple and Biscuit” Omni-direction pressure gradient.

STC 4021c

I’ve been after one of these for a while.  The famous  STC 4021c “Ball and Biscuit” or “Apple and Biscuit” (depending on which BBC engineer you ask).  The STC 4021c is an Omni-direction pressure gradient microphone which resembles a small cannonball.  It sounds best as a drum mic with a genrous amount of FET based compression.

Altec 633A

The Altec 633A, “Salt Shaker” microphne was sold under different brands, such as Western Electric.  This one is branded Northern Electric.  A quick look inside to rewire it for XLR operation revealed that this particular design is from 1941.  It’s interesting to note the tube which equalises the pressure at the rear of the capsule making it uni-directional.

Sound Engineers EDC

Sound Engineers EDC

EDC is a term used by Survivalists and Preppers, it means Every Day Carry.  EDC can just be the thing you carry on you each day – sunglasses, wallet, keys, etc.  However, it can also mean a prepared kit of useful tools and objects.  With this in mind, I have developed a Sound Engineers EDC over the past couple of years, bear in mind that this is always a work in progress and gets updated regularly.
