MN-Series interference suppression filter / noise filter (MN-FILT)

This MANTSON interference suppression filter puts an end to interference noises caused by the on-board electrical system, such as alternator and switching noises. This filter is Plug & Play that is placed between the MANTSON box and the cable for the CD changer input.

In which cases to use:
1) A screeching whistle through the radio/amplifier, varying in pitch with engine speed.
2) A ticking sound in the radio/amplifier that varies with the engine speed, frequency usually 1/4 of the engine speed.

Remark:
If the engine is off and the fault is present, there is little point in using this interference filter. The only exception to this rule is the fuel pump, which can make ticking and crackling sounds even when the engine is off.
