CardioidBock Audio 151

MSRP: $3,325 Cardioid Condenser Tube Microphone

Bock Audio 151

Description

Essentially a budget version of the flagship Bock 251, the 151 was designed for close-miked applications such as vocals.

It uses a proprietary, hand made capsule, a proprietary hand-wound vintage style transformer, a NOS tube (New Old Stock GE5670 triode) in the mic amplifier and a hand-built custom outboard power supply.

The “brite/normal” switch delivers two sounds in one mic:

  • “Bright” allows unfiltered extended high frequency response that defines a modern high end condenser.
  • “Normal” offers a less bright, more vintage style high frequency response more forgiving to sibilant singers and or voices that need a darker treatment.

The Bock Audio 151 is also known as: E251C.

The mic was released in 2007.
