I'm planning to record some voiceover audio on-location using my Macbook (didn't have time to book a proper studio) and am having some trouble. I've got a Sennheiser 416 connected to a Beachtek DXA-4 with a T-Power supply in between. The Beachtek then connects to my Macbook's line-in via 3.5mm audio jack. The problem is that the audio is coming through REEEAAALLY quiet. Around -40db I can Normalize it to bring it up to decent volume, but then there's heaps of hiss and sounds like it's almost clipping. The T-Power unit is on and has fresh batteries, the Beachtek levels knobs are on full and my Macbook's line-in is set to full volume. I'm thinking I should probably go back to the hire place and ask for a field mixer which can supply phantom power, instead of using the whole Beachtek + T-power thing...?
