■Preamp and attenuator

The preamp amplifies received signals in the receiver input (front end) circuit to improve the S/N ratio and sensitivity. Turn this function ON when receiving weak signals.

The attenuator prevents a strong undesired signal near the desired frequency or near your location, such as from a broadcast station, from causing dis- tortion or spurious signals.

Push [P.AMP/ATT] momentarily to turn the preamp ON and OFF; push and hold for 1 sec. to turn the at- tenuator ON.

•“ ” appears when the preamp is ON; “ ” ap- pears when the 12 dB attenuator is ON.
