Does the LBT-D505 have a phono input?
No. You cannot connect a turntable directly unless it has a built-in preamp. Use an external phono preamp between the turntable and any line-level input.
Why is one channel quieter than the other?
Dirty volume pot or balance control. Turn the unit off, then rotate the volume knob back and forth 20-30 times (no sound) to clean internal contacts. If that fails, use contact cleaner spray.
