Hmmmm.
They are an interesting system. They are a two channel recorder,
using custom omni mics. The recording quality is quite good, but
not up to say a pair of Sennheiser ME-62's on a Fostex Fr-2LE.
(All I have to compare to). Still, with minimal editing they
produce a very usable recording.
You can either mount the mics directly on the box, giving you an
AB array with a seperation of about 20cm, or you can use
extension cables - up to 50m. I typically use a 3m extension
cable and mount the two mics about 2m apart.
You can also get ultrasonic mics, and hydrophones, allowing you
to play with all sorts of combinations. We use one audio mic and
one hydrophone to record above/below water soundscapes as heard
by platypus....
There's lots of other tricks the box is capable of too. It has
very complex scheduling abilities - for environmental sampling
you can set it to record for 10 minutes every hour, or from
sunset to sunrise, or 3 hours every day, or...
It can record at up up to 96kHz 16-bit, or you can buy an option
to go up to 196 kHz.
Takes 4 x SDHC cards, so has a fair amount of memory.




I use it mainly for getting 24-hour recording in flying-fox
camps...recording at 48 kHz 16-bit this gives me a continuous
recording of what's going on, straight out of the recorder it's
clear and usable for analysis, but with very minimal editing it's
actually quite listenable as well.



Of course, it's not the same quality as (say) a pair of MKH-20's
into a SD 702. But it's weatherproof, autonomous, and a fraction
of the cost.

Horses for courses.




Cheers...

I've heard of those. How does the recording quality compare to,
say, an M10?
