Adding EQ to Peachtree 220SE?

I have been scouring the web for an answer to whether I can run EQ to my Peachtree 220SE, but I can't seem to find an answer. I understand that in the newer Peachtree amps you can use the loop feature to add an EQ, but this is obviously not an option for my model.
please help!! Thanks :)
Thank you for this! Forgive my ignorance on this unit, but how exactly would I hook up an EQ? I am indeed only using one digital source.

Hi OP,

The unit itself is an EQ, plus crossover and time delay. You don’t have to usue all the features though. :)  It has digital inputs and outputs, so you'd hook up your streamer or CD player on one end and your integrated on the other.

You’d use a computer to adjust the EQ settings connected via USB.

Another alternative is to use something like Roon as your source which has built in EQ capabilities.
