Audio-Technica BP40 Reviews
Built like a tank with great sound for VO work
I've recorded one audiobook with this mic and I love it. No need for a popfilter, it's a very forgiving mic but still gives a great full sound, I started with the AT 4033CL and this mic sounds everybit as good with out picking up dogs barking a block away. I'm half way done with my second project and I'm not going to add any post work to it, no need. The shock mount is a cheap feeling polymer plastic but its held up great and has a quick release that is usefull. It does take allot of gain to push this mic I use a FetHead with a Clarett 2pre set at 7 to get about -3db of head room in Logic pro X with a floor of around -60 to -55.
An excellent quiet dynamic microphone for podcasts and VO
This is an equal to the other dynamic broadcast microphones. It rejects room noise well and sounds more like a condenser mic than a dynamic mic. Very well suited to podcasting, voiceover, and broadcast. I'm surprised that it hasn't risen to popularity alongside the other dynamic mics in its price category.
