Can I use a line level signal other than a record player on the Phono input?
Since the Phono input uses an RIAA preamp to properly reproduce music from a record, you will not be able to plug in any line level device without some modification to the signal first. The RIAA preamp has EQ curves built-in that will need to be corrected in order for your music to sound right. You will need to build a circuit to make this work.
