Hi all , first question here !!! Nice to find this place ... I have a pair of CA-14 mics , 1 card , 1 omni mics to go with my sony PCM-M10 . Im wondering if the built in phantom power is enough for either pair of mics for around 2 hours .? A short test sounded great with the omnis . I plan on recording a guitar player only at a local theater . I have a battery box , pre-amp in one but why use it if it's not needed . This is my 1st recording using my new sony that i just got . Any advise will be great and very appreciated . Thanks all , looking forward to being a member here .
