Re: Bought a TLM 103D how does it work?

The TLM 103-D is a digital microphone to the AES42 standard.

There is no point at all in converting the signal to analogue.

If you only use the one microphone you will need the Neumann connection kit - this will convert the AES42 to AES3 and supply the 12V phantom power to the microphone.

I can't find any information on an Edirol UA24, but I can find the UA25 - did you mean UA25?

The UA25 has an optical digital input - so you should get the S-PDIF version of the connection kit and an S-PDIF to optical converter.

The DMI-2 (or DMI-2P) is the better option, however, as it allows microphone adjustments of the microphone via computer - but this is more expensive.

On my own digital microphone set-up I actually have all the options - I have a connection kit, DMI-2 and two DMI-2P - the DMI-2 is the most flexible.

But the outputs of these devices are either AES3 or S-PDIF - whichever you use you will need an extra converter to go to optical.

But don't convert the signal to analogue - there is no point - if you do this you should have gone for the TLM 103 analogue version instead of the TLM 103-D.

When I started recording with digital microphones I did a write-up on the Sound On Sound forum - you can read it here:-

I also wrote a couple of AES papers on digital microphones:-

I hope this helps.
