I read your JL Audio Gotham review and you were using TrueRTA software with the Behringer ECM8000 microphone for frequency-response data collection. I have purchased the ECM8000 and it requires a phantom power supply. Do you use a preamp or the Behringer PS400 to provide phantom power to the ECM8000? As of now, I am using the RadioShack SPL meter with TrueRTA and I would like to set up the ECM8000 to get better results.    

I am looking forward to your reply.

Best regards,

I use an MXL Mic Mate line-level XLR-to-USB adapter. It provides the phantom power supply for the microphone and interfaces with your computer without any additional drivers required. It is dead simple to use, and is also fairly inexpensive. . . . Jeff Fritz
