The AG-HMC41 comes equipped with a built in sterio microphone and a 3.5mm EXT, mic-in jack.
Adding the optional AG-MYA30G XLR adapter provides compatibility with professional use XLR terminals for audio output from microphones and Public Audio (PA) systems in studios and auditoriums. Line recording and +48V Phatom powered microphone recordings are possible from the XLR terminals. Featuring two XLR audio input terminals and level controls, the adapter lets you independently switch ch 1 or ch 2 to microphone or line input, with each having its own level adjustment.
(Input 2 can be assigned to both ch 1 and ch2).
