What is the preamp?
The preamp amplifies signals in the receiver front end (input)
circuit to improve the S/N ratio and sensitivity. Turn ON
‘P.AMP’ when receiving weak signals.

desired frequency or near your location, such as from a
broadcast station, from causing distortion or spurious sig-
nals.
