First off, not the most scientific comp ever. Just recorded from my front porch, pointing towards the woods across the street from my house! I just wanted to give other tapers an idea how quiet the 70D preamps were compared to my VMS02IB preamp, which was run at +40db! Since I mainly do amplified, loud music, they don't need to be ultra quiet for what I record! You can judge for yourself if they are quiet enough for your needs based on this comp! Later today, I'll be recording some louder traffic and stuff at my relatives down the street, to give everyone an idea how quiet the preamps are, comparing something very silent like the Birds samples posted below vs. the louder sounds of traffic going by at close range!
OK, just did some super quiet recording of the birds and nature around 6:30am this morning[6.19.2016]! These are the RAW untouched files, just FLAC'd@Level 8 with TLH! I ran the mk41s with all four gain modes[LOW/MID/HIGH/HIGH+PLUS] of the DR70D, just so yinz could all hear the internal preamps with some quiet mics
Both setups were in Rycote INV6-HG Shocks, with Movo WS80 screens on! The mk41s were ran in DINa, and the mk4s ran ORTF! Tascam 70D run with v1.13 FW!
