All Clear coils come in pairs so that you can use them on separate left- and right-channel electronics, or so you can interleave them for more powerful RFI suppression.

Unplug the component from its power source. Fold the power cord or cable in half or measure to find the center. Mark the center with tape or marker pen.

Twist the All Clear around the cord or cable. An easy way to do this is to hold one end of the coil with the cord and wind the cord through the coil. Slide the All Clear so it is centered on the cable.

If you are putting two All Clear coils on the same cord, wind the second one onto the cord. The bent ends should face each other. Interleave the two All Clear coils together by turning them towards each other. You may also leave the coils apart, with their ends touching at the center of the cord.

Plug the power cord into the AC source, or plug the audio cable into the system. Turn on the component. Start to listen to your system. We suggest you use a wide band vocal recording.

Move the All Clear back and forth by 1/8 inch at a time to get the most bass. The center of the location with the most bass is the electrical center of the cable. Use that point as the reference starting point for adjustment.

Move the All Clear toward the electronic component (away from the source). Move 1/8 to 1/4 inch at a time. Listen for top-to-bottom balance and good midrange. You will get more top end as the All Clear is moved closer to the electrical component. The optimum point is generally located within 1/2 to 3/4 inch of the center of the power cord.

Tape or tie-wrap the All Clear in place or gently bend the ends so it won't move accidentally.
