Does anybody use this converter in the studio with a console?

Yes I use it on a console. See my signature.
I have the MKIII the MKII and the 24 I/O.

MKII is connected in my system but use it only when I need those 8 analog I/Os as extras.
However the difference between the MKII and MKII is significant.
MKIII is a true upgrade and is sounding so much better than the MKII.

The 2408 are reliable and wonderful to work with. So many different connectors: Tascam, TOS and analog I/O. I´ve used all of these from time to time.

My review score is about the 2408MKII.

If the review would have been about the 2408 MKIII the score would show 100%.
FYI the 24 I/O and the MKIII do have the same high soundquality and do sound equal.

I run an motu 2408 mk2 system in my studio because i like the possibility the connect everything a want. The converters are not high end but ok for special things(like dark guitars).
It is a total workhorse and absolut cool when you need a lot of channels.
The drivers are rock solid and i never had any problems with the software. The only thing i don´t like is the clock. I run an external clock and thet is a much better result.
I like the motu very muck and it is a good sytem for your daily work. Go for it ;-)

the MK1 had RCA Input & Output connectors for the Analog audio.
the MK2 changed to female 1/4" TRS.

it had a PCI card and a PCIe was also developed.
it connects with a cable similar to FireWire but is not, the Moru 2408MK1/2/3 interfaces cannot be connected to FW.
up to 4x interfaces can be added to a single PCI card..

the ASIO drivers were OK, but at low latency they eat CPU, WDM drivers can be used for Surround AC3 decoding, unlike Digi001/002 that cannot.

to download the drivers must be registered in the Motu website.
and Owners Manual if needed, must be purchased hard printed copy & cannot be downloaded as a PDF.

the PCI card & drivers were sensible to motherboard chipset.
Intel chipsets needed a INF installer.

i liked the sound of the AD/DA converters. not the best in the world but better than Tascam DA-30MK2, "i was using a bad s/pdif cable, so who knows ..."

the internal clock in the MK2/pci-324 is not the best... they sound a lot better with an external clock.. the MK2 its limited to 48KHz. MK3 to 96khz.
the New MK3 clock is DDS, similar to RME SteadyClock(TM), not the best either.

because Analog I/Os are DC coupled, it can be used with MOTU Volta software, and Expert Sleepers Silent Way VST plugins, to control Analog Hardware Modular Synths with CV.
that was a very nice idea that keept old Motu hardware away from trash.

in its time was the competition of the Digi001,
but the 2408MK2 does not have Mic-pre or Midi I/O.

it could be used as a stand alone format converter between ADAT or Tascam TDIF, settings must be made with front panel push buittons.
