We designed the V2 with concert recording as its primary application,
though it works fine for quiet dialog too. We designed around the
sensitivity specifications of two fine miniature microphones: DPA's 4060
and 4061 (as used in our High End Binaural microphone sets). With the
DPA 4060 (20mV/Pa), our customers can record loud concerts with the V2's
level controls at near minimum, and moderately loud concerts with the
levels turned up only a bit. With the 4061s (6 mV/Pa), they can record
extremely loud concerts with the level controls at near minimum. For
quiet recordings, the target was DPA's 4003 (40mV/Pa) -- its high
sensitivity allows Mic2496 to use low gain settings and provide fine S/N
performance.
When you select microphones to use with the V2, you should choose
microphones that have sensitivity specifications similar to above three
microphones. If you choose to use a low sensitivity microphone (e.g., a
ribbon mic or a dynamic mic like a Shure SM-57), you'll have to turn up
Mic2496's level controls near maximum and will hear more background
noise.
And as with most mic pre-amps, the lower you set the gain, the lower
the mic pre-amp noise you'll record.
Remember that with 24-bits of resolution and more than 120 dB of
dynamic range available, you should now set your recording levels to
peak at around -25 dB or even lower. At those levels, V2's true 24-bits
gives you around 100 dB of dynamic range, mcuh more than is usually
necessary. With 25 dB of headroom, you'll be in little danger of
encountering digital clipping. You can add gain later in your DAW as
necessary; adding gain there adds no additional noise.
