The VR2 has an easily accessible external adjustment of the most important acoustical reactors in the dynamic microphone. A smooth change from a communication-type response, with a cutoff below 500 c. p. s., through a flat response to an augmented bass, attained by a simple, positive adjustment.

Noise and hum are minimized by the use of double - wound, helical heaters, and a new base layout which keeps heater leads well away from the grid leads. Low microphonism, high mechanical strength, and reli- ability are assured by a short, rugged cage which provides sturdy support for the tube electrodes. New base arrangement also simplifies stereo layouts.
