I was/am happy about my sE X1, however it do pick up more unwanted sounds (e.g. the sound from the PSU- motherboard- and cabinet-fans of my computer), hence I most often needed to clean up my recordings afterwards (not a big problem, but still one more task to complete). So at a time I had a few extra bucks burning a hole in my pocket (after having sold of a few hardware synths), I decided to go shopping for an extra microphone. The choice ended up being the Shure SM7B, which many sees as a pure "broadcaster" microphone (its used in many radio-studios around the world). However the SM7B works equally as well recording artists singing (e.g. most of Michael Jacksons voice was recorded for the Thriller album on a Shure SM7 - the predecessor to the SM7A/B). Consider its heritage in the broadcasting industry this microphone is perfect for voice over, and mounted on a RØDE PSA-1 table-stand/arm you can easily place it in front of your mouth. The foam windhood doubles as a pop-filter and the microphone has a build-in shock-mount. According to Shure it can handle over 180 dB SPL (human pain threshold is around 140 dB SPL), so it will work equally well recording a heavy metal "singer" screaming into the microphone, or recording the sound of a Boeing 747-400 spooling up its engine to max - I don't care much for heavy metal - I think my pain threshold is around 40 dB SPL when it comes to heavy metal - so I would actually prefer the sound of the 747 :-)
Most dynamic microphones are more quite compare to condenser microphones, and the SM7B is notorious quite (it needs 60 dB of pre-amp). My RME fireface is cable of delivering 10-60 dB of gain, but then you need to ride the gain by fully turning up the gain-knop. You should never ride the gain like this, as it will cause distortion and bring noise into your recordings. So between my SM7B and my audio-interface I have placed a Cloudlifter CL-1. The SM7B being a dynamic mic it don't need phantom-power, however the Cloudlifter does. The Cloudlifter uses this power to add a fixed (very clean) 25 dB amplification to the signal from the SM7B, and it will then send this amplified signal to the audio-interface, meaning you can dial in a much lover gain in your audio-interface (and thereby avoid the problems associated with riding the gain). All you have to do is to insert the Cloudlifter into the signal chain between the SM7B and your audio-interface, and enable phantom-power in your audio interface (the Cloudlifter will use this phantom-power, but will not pass it on to the microphone).
