VINTAGE BROCHURE #1 | VINTAGE BROCHURE #2

Up for sale is a vintage Altec 633A dynamic mic in good condition. This Salt Shaker mic was designed for omni response in the vertical position, and it gains some cardioid properties as you tilt it toward the horizontal. These mics that were designed for preamps that are no longer made, as 20 Ohm transformerless mics are not optimized with modern preamps. Because of this, this mic includes a 20 Ohm to 600 Ohm transformer adapter specifically designe to remedy this problem, containing a Shure transformer coupled with a 600 Ohm output, giving the mic additional gain and a fuller tone when used with modern preamps.

These vintage Western Electric / Altec dynamic mics are a lot of fun to own and use, as they are quite often useful for several things, and don't cost too much money. This model also has a wonderful industrial design that might be inspirational in itself. The mic is hefty, and built like a tank. Comes with the original swivel mount, a new hardwired USA-made mic cable, and a new Cathedral 20-600 Ohm transformer adapter.
