Why Do You Need a Speech Processor for Your CB Radio?
Two-way radio communication relies on the modulation contained within the signal. Maintaining a high modulation level is crucial in providing the highest possible efficiency from any transmitter operating on AM, FM, or SSB modes. Two-way radios also rely on microphones that inherently change audio levels delivered to the transmitter. This causes transmitter modulation to fluctuate greatly depending on voice level and pitch. The average modulation of a typical voice signal is only about 40%. This low percentage applied to the transmitter, results in less than optimal transmission range. Other Processors Have a Problem... Other speech processors use a low-cost "audio clipping" approach to achieve compression. While this method is economical for the manufacturer, clipping distorts the original signal and sounds fuzzy on the air. What these types of audio processors gain in volume, they lose in voice intelligibility. VoiceMax is Different... VoiceMax uses a sophisticated AGC (Automatic Gain Control) circuit that installs inside your transceiver to hold the audio level constant, with less than 1% harmonic distortion. No "clipping" type processor can come close to this low distortion level. Whether you're whispering or shouting, VoiceMax holds your transceiver at 100% modulation allowing you to punch through heavy channel traffic without sacrificing voice clarity. VoiceMax incorporates a feature not offered on other processors. The adjustable noise gate allows the user to block unwanted ambient background sounds. This feature is especially helpful in mobile environments where wind and road noise can be an issue. VoiceMax works with your non-amplified dynamic microphone to give you tremendous audio punch without all the background noise associated with power microphones. www.telstar-electronics.com |

However we know that cbers are like audiophools, they will buy into snake oil that they think will give them that "big signal". |

You, quite obviously, have never heard a, good, real speech compressor in actual action--under adverse conditions ... It is even possible to pick up a guys compete audio when his signal won't even register on your meter ... On equal signals producing a heterodyne--you'll hear the guy with the speech compressor ...

JS I have heard many speech processors. Most were either of poor design or mis-used by the operator so the audio sounded like crap. A good speech processor, properly adjusted can enhance the signal, but none can "hold the modulation at 100 percent" as the snake oil salesman claims. |
