Hi everybody.. I'm really new into audio recording field. Currently I want to setup a 4-channel simultaneous recording (I'm buying CoreSound's TetraMic which only works if the four mic channels are recorded simultaneously). I'm looking for pre-amp to interface the mics and the manufacturer suggested MOTU Traveler. Some things are dark to me: 1. Is Traveler only a pre-amp, or does it also perform the recording (analog to digital conversion)? How can I tap the digitized mic signal to my PC? I'm thinking of Creative S/PDIF or Optical In, but will it work for such case? 2. Hence, do I still need separate multichannel ADC/soundcard to record the analog amplified mic signal from Traveler to my PC? I hope I don't get the mic-preamp-ADC concept wrongly. Please advice me on this and thanks beforehand Regards, Sam.
