Hi. I need some advice. Been using the tascam dr-70d for years and have no issue until yesterday. Using it with 3 wireless mic and one shotgun mic powered by its own as battery: when using USB power all four channels started to flash red (peaking) plus sending clicking signal. When using batteries they only last 10 mins. So a lot of aa batteries used. Any suggestion how to troubleshoot?
This never happened before and I'm using latest firmware.
