RF Limited EC-2018 Turbo™ Echo Mic
The RF Limited EC-2018 Turbo™ echo mic is the first echo
mic with digital echo. It is also the first with both echo delay and echo
volume controls on the outside of the mic. In addition, RF limited was the
first to incorporate talkback in their echo mics. RF Limited has always
been innovative with their products. They have spent time and money in
developing products that the end user is looking for and this is also the
reason they have the most copied products in the CB and Amateur radio
market. Somehow though, the copies aren't as good. The copycats clone the
packaging, but where it can't be seen, they cheapen it. If a RF Limited
mic was side by side with one of its copies, you would immediately find
the tone quality of the copy to be muddy sounding while the RF Limited mic
would be clear and crisp sounding. Muffled modulation won't cut through
all the garbage out there on the air, you get what you pay for.
The EC-2018 Turbo 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.
Their slogan for this mic is "The Next Generation of
Echo Microphones". Also two new sounds were generated from this mic.
First is the Alien Voice™ sound effect. This is a metallic sound to the
modulation when the echo delay is set to minimum and the echo volume is
set to maximum. This is much more understandable than the Galaxy Robot
Voice. Second is the Whammy™ sound effect. This is generated by setting
the echo volume to maximum and the echo delay about mid way and changing
the delay as the echo is repeated.
The audio quality of this echo mic is still the best of
all the echo mics on the market. With or without effects the audio is
great. And for a power mic, the background noise isn't too bad. The echo
delay at maximum will repeat about three words six or seven times before
completely fading out. With the delay stretched out that long, the
reproduction becomes distorted but still understandable. With the delay at
a normal setting, the audio reproduction is very clear and natural. Check
the samples below.
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 even tried one on a Tram D201 tube rig. It sounded
outstanding. 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, great results. The mic is so clean it works
well in conjunction with other echo boards. They are available from Bob's
CB & Wireless for $49.95. http://bobscb.com
