33609 Power amp question

[college101]

I was convinced I had the Power amp section nailed down in my understanding..Now I am starting to question myself..I have GroupDIY as a resource! gotta ask a question!

If you look at the pictures of the schematics I am attaching- i am trying to understand this Neve schematic. From the Power amp, the to pins in question are the opamp V+input and the V- input pins... 

Which one comes from RV1?  I believe its the negative input

see the BA640 amp section...

Here is the BA640 schematic I was referencing...

as you can see... the power, ground 0 volt and Output are easy to distinguish

The input side on the other hand- is where I am getting confused...  Based on the BA640 schematic, I believe the RV1 on the main schematic goes to the negative Vin of the Power amp...Is this right guys??
