How can humm be stopped when tone controls are used?

Use quality cables and good ground circuit

Will this work with my headphones that I have wired from my TV. The volume from the optical port output from the tv cannot be adjusted. This device seems like it would allow me to raise or lower the volume. Thanks.

The PFA200  does not have an OPTICAL input

Does this have input for a ground wire?

There is o Ground wire connectivity on this unit

Can I connect earphone outlet from player to the input?

Yes, you can connect the earphone output from your player to the PFA200 input. Just start with the volume low on both devices to avoid distortion.
