I have been really happy with the sound captured by the Tascam DR-40 when attached to a mixing board via XLRs or when using a condenser mic handheld (for interviews). That said, the quality of the built in mics does not cut it for recording live musical performances with sufficient clarity and definition.
Enter the new mobile audio rig: I can raise the stand over 10 feet to get above the crowd and with built in phantom power the matched pair of condenser mics sound amazing. I can’t wait to put this rig to use when shooting video of a live performance. I also purchased the BP-6AA which increases the run time to around 50hrs. This is going to be handy and it breaks down into a remarkably small kit.
