What is UA Bock 251?
UA Bock 251 microphone is a multi-pattern tube design of the highest quality. Offering Omni, Cardioid, and Figure-8 polar patterns, extended low-frequency response, and high sound pressure level tolerance, we trust this microphone will become an indispensable part of your recording studio.
Engineered by David Bock and inspired by the iconic 251, the UA Bock 251 is ideal for capturing vocals and musical instruments.
How do I mount the microphone in the mic shockmount?
Thread the included shockmount onto a 5/8"-27 thread microphone stand. Loosen the clasps on the shockmount, insert the microphone, and re-engage the clasps to secure the microphone in place.
What is the switch on the microphone?
UA Bock 251 has a polar pattern selection switch with cardioid, figure-8, and omni options.
Which direction should the Bock 251 point?
The UA badge indicates the front of the microphone. Since the UA Bock 251 is a side address microphone, the UA badge should be facing the sound source.
Likewise, the black portion of the headgrill indicates the back of the microphone, and should be facing opposite the sound source.
Which cable should I use for my Bock 251?
UA Bock 251 should only be used with the included proprietary six-pin Tuchel cable.
