RF Limited XTR-2018 Xtreme™ Echo Mic

This is the latest echo mic from RF Limited. As the name suggests, it’s turbo echo to the extreme! In addition to the features of the EC-2018 Turbo, it has Cyborg™ Robotic Voice, which is another name for Alien Voice™, Endless Echo™, Stadium Sound™, Double Talker™, and a richer tone quality that can be best described as studio quality.

To best describe the Double Talker™ effect I have to mention the Astatic Echo Max 2000™. It is the same as their Slapback™ effect. It is a one time repeat instead of a fading echo.

Like the EC-2018 Turbo, the EC-2018XTR runs off of a 9 volt battery. I strongly recommend an alkaline type or if even longer life is desired, pick up a Radio Shack 9 volt lithium battery.

Below is a table with the approximate settings for desired effects.

Below are audio samples of the different effects. Notice the difference in tone quality between the EC-2018 Turbo and the EC-2018 Xtreme™. All the sound effect were recorded with the same equipment at the same settings and with no equalization. The only difference is the microphones, and they are stock from the factory.

The most common wiring available is the 4-pin Cobra/Galaxy/Uniden, although it can be wired to any radio on the market today. I’ve also tried one on a Tram D201 tube rig. It definitely has a studio quality sound on this rig.

I’ve also used one with a Magnum Delta Force, setting the mic and the radio internal turbo echo to different settings in order to create a different sound effect with, awesome results. The mic is so clean it works well in conjunction with other echo boards. They are available from Bob’s CB & Wireless for $64.95. http://bobscb.com
