Hi Stephen,

Manual adjustment of the EQ via the on screen display of the Model 976. I recommend a PC utilizing REW with an HDMI output to the Model 976 and utilizing ASIO4ALL drivers; this allows you to run your tones for each channel independently via one HDMI connection.

I have had good results with the MiniDSP UMIK‑1 USB mic; the serial number can be entered into their website to download the calibration file of your microphone and then you can upload it into REW.
