Adding a tuner between turntable and 5

Pro-ject carbon turntable to am/fm tuner to 5? I’m trying to figure out this setup. i have two 5s, currently with a line in from the turntable. I’m worried adding a tuner into the mix will bring issues with turntable audio quality without an amplifier.
 

I purchased an ADCOM GTP 400, and it needs an antenna to work getting local broadcast l, but when I tried to play a record, it sounded awful.

I want to stream local baseball games from time to time, so I want to keep the budget reasonable, but absolutely open to investing in quality equipment and can return the Adcom if I need something different. Any advice from the community?

You have two options:

  1. Setup another line-in from the tuner to the other Five
  2. Place a switch (selector) between the Turntable and the tuner and keep the same line-in to the Five you are using now.

Either option allows you to use the turntable’s built-in pre-amp and by-pass the Tuner circuitry.

      Not widely discussed, but a phono preamp (internal or external) or the Phono input on a reciever provides both amplification of the very low level signal from the cartridge and applies an equalization to offset the one used to record the album. See RIAA equalization for details. 

      https://en.wikipedia.org/wiki/RIAA_equalization

      That means you need a phono-preamp, but only one to get listenable sound from an album.
