Hi, long post. Hopefully someone can help me. Tried on other forums, but no luck yet.

I have no experience with REW yet, so have to get into that stuff. But before I start with that, I have to know if I can use the hardware I need. Hope I can get some help with selecting a good Minidsp device for my situation.

First my setup:
Stereo amplifier: Marantz model 30 (Integrated phono stage)
Speakers Front: B&W 702S3
Subwoofer: B&W DB4S
Turntable: Marantz TT-15S1
Cartridge Turntable: Sumiko Moonstone

Room: small (about 14 square meters)

The Model 30 stereo amp is connected via Pre out to a surround receiver.

Now, what I want is to measure the room acoustics to see where the issues are and treat the room consequently with panels, bass traps, etc. I already own a UMIK 2 microphone. I don't do anything with streaming or digital music listening, only LP's (analogue source). To install REW I need a MiniDSP as a device. The main question is: which type do I need (Flex / 2x4, etc) and how to connect this. Maybe important information: I use the integrated phono stage of the stereo amp.

I want to measure the room acoustics and after that import correction filters for front speakers and subwoofer integration (2.1).

Would this work:

• Analogue source (Turntabel) ➡️ Phono in connection of stereo amp
• pre-out L and R stereo amp ➡️ input 1 (L) and 2 (R) MiniDSP
• Output 1 and 2 MiniDSP ➡️ Line 1 in (L and R) amp (Note: can't use the Power amp in, already reserved for connection to AV receiver)
• Output 3 MiniDSP ➡️ Subwoofer phono in connection

So, what MiniDSP is right for me and how do I connect it?
