Bock Audio is known for its for using modern methods and readily available components to build microphones with a sound akin to the great microphones of the past. The 4ZERO7 continues in that mode by using the Power Supply and Amplifier from the flagship 5ZERO7 microphone and combining a custom made k47 type capsule to bring the performance of the original 50's era German tube 47 in an all new 4ZE?
