Passive DI Box is this right

Is this the correct way to wire up a passive DI box with ground lift and a -15db and -20db pad. As I can work it out this is the direction ChatGPT has given me on, but not 100% sure I total trust my interpretation (or there instructions). Main switch is a DPDT On-On-On

Thanks

-25dB? What are DIing?!?
Anyway, looks okay at a glance. Be sure to use an isolated/insulated jack or it will defeat the ground lift. Careful that the ground to the transformer body doesn't defeat it as well. And ditch the ground loop between the transformer and - input.
Will whatever you are plugging in be happy with a 1k input impedance?
Oh, and be careful with type 1 vs type 2 DPDT. I think this is drawn for type 2 from the looks of it.

Thanks for the feedback. Am I using a 25db pad? Which of the 2? Those DPDT switches have really fried my brains. Going to use the Di box with line level and get the impression that the 1k resistor will be ok for that. Will take the transformer out of the ground.
