1st post- New 2 vinyl. Pro-Ject Debut III question

This is my first post. I just purchased a Pro-Ject Debut III TT. I just realized it has a built in phono stage. I am running a Sunfire Theater Grand II Pre/Pro with a phono stage. Do I connect the Debut III to the phono inputs or should I connect it to another rca input like "tape"? Thanks in advance.
connect it to your aux input if you are using the built in preamp. or the phono input if you are not.
I just read the owner's manual and doesn't say anything about a built-in phono stage? It says to connect it to a "phono" input. Are you sure it has a built-in unit?
With the others here.

If Turntable has a built-in Phono Preamp, then just plug it into the Aux. Input of the Linestage.

This Turntable does NOT need an external Phono Stage.

I am not sure where I thought I read about the Debut III having a built in phono stage but it does not. Thanks to everyone's posts. I appreciate it.
