Questions about Pro-Ject Phono Box E

Yes it will. I have the Debut Carbon, and this is what I bought. The Evo will be the same. Generally, it’s pretty standard. If the turntable doesn’t have a built-in pre-amp you need an external one and this one will do the job.

Not sure I understand the question. This box amplifies the sound from your turntable to your amp. Your amp amplifies the sound to your speakers.

It depends on whether the record player already has the phono preamplifier integrated. If so, you don't need anything else to use it. If not, then you need a preamplifier. Pay attention to what kind of cartridge (needle) you have on it. There are MM and MC cartridges and you will need the preamplifier accordingly.

Hi, in principle this should work. From what I've read, Sonos Port has a line-in input. I have connected my record player to another similar Multiroom system with the Project Phono E Box. But the question is better placed with the Sonos Port. I would ask it there to be sure (if you haven't already) if you can hook up your turntable with a phono preamp (turntable brand is irrelevant). Hope this helps a bit. Many greetings

What kind of Bluetooth transmitter do you have in mind?

B&O has often used a 4- or 5-DIN cable for its hi-fi components which, in addition to the audio signal, also contain a connection for the Bose control signals. Therefore, B&O unfortunately does not work too well together with "commercially available" additional products. Accordingly, this preamplifier from Pro-Ject is not suitable for interaction with B&O. We do not carry such products.

I don't think this helps. The phonobox is a preamplifier for MM cartridges to use a connection to a classic AUX input of an amplifier.
