Series 3468 suppress interference or reduce spurious carriers. They are easy to tune with two self-locking screwdriver adjustments. (There is only one tuning adjustment for the 3468-FMS.) They are housed in a seamless steel case sealed against moisture. The traps can be experimentally adjusted to reduce out-of-band interference whose frequency may not be precisely known. Each tuning screw controls the frequency of a separate, sharp notch which may be used independently or synchronously to give the notch and bandwidth shown. For a nominal extra charge, units can be tuned and marked to specified frequency.

3469 Series Series 3469 are sound carrier traps used to reduce sound carrier levels. These are narrow band notch filters which are tunable with a self-locking screwdriver slot. Controlled sound reduction with minimum impact on color is achieved by tuning into the sound carrier from a higher frequency (clockwise slot rotation.) The 3469 can be factory preset to customer specified frequency.	Larger View Download PDF
