Hi
I have doubts about how to use the RTA analyzer in dolby CP750.
For alignment, I use the D2 with multiplexer and USB PRE2.
I connect the microphone output to the input of the CP750, and it allows me to calibrate the SPL, but the RTA meter and the sound pressure of the CP750 remains fixed, however, in the D2 it acts normally.

Although makes variations in the different frequencies, the RTA of 750 continues without moving, but in D2 it responds perfectly

Do I have to do some configuration within D2 to be able to see at the same time the RTA of 750 and D2?

Thanks!

I haven't used that for a while but if I remember well The RTA on the 750 is always centered to the 0dB line. That is, if you raise HF, you'll see the LF going below the 0dB line as a result. It behaves like the D2 but imagine the graph is always centered on the screen.
