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
