The higher end BOCK AUDIO 251 (formerly Soundelux E251C) is treasured by users for its extraordinary up close cardioid performance on premier voices and its distance performance on piano, ensembles and orchestras. Many of our customers have asked for a vocal mic only version at reduced cost and this drove development of the BOCK 151. The 151 is a microphone designed to sound as close as possible to the flagship BOCK 251 up close but cost 30% less. What makes the 151 different? The BOCK 151 Microphone uses a proprietary BOCK hand made German capsule, a proprietary BOCK hand wound vintage style audio transformer, a NOS tube in the mic amplifier and a BOCK hand built custom outboard power supply. The BOCK 151 adds a unique "brite/normal" switch which 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 151 offers enduring qualities impossible to fully describe in writing. While Chinese condensers try to impress with lots of top and bottom end on first listen, they lack midrange so critical in defining a great vocal. The BOCK 151 built-in midrange presence curve, so important in “cutting through” a dense mix, is impossible to obtain through EQ. Time has proven this vocal sound must come from the mic itself. The unique BOCK AUDIO "brite/normal" switch adds long term versatility. The high frequency response is extended but never gets harsh or gritty. The BOCK 151 Proximity Effect (bass gets stronger with closeness) is naturally powerful without being too boomy or bottom heavy. Midrange is smooth and does not require post EQ. Best of all, the BOCK 151 has a way of lifting the singer’s vocal to a higher level when they hear themselves for the first time on this great microphone. The BOCK 151 primary use will undoubtedly be female and male vocals. Use a pop filter and get up close for that intimate “big vocal” sound. A few inches away, the proximity effect recedes and the mic gets flatter in response. At distance, the BOCK 151 is amazing on instruments and ensembles. In front of a drum set it sounds like you are standing there; on stringed instruments it captures the transients and complex harmonic structure that spell the difference between good and great.
