Telex now has the ProStar Series of wireless transmitters and receivers available in both VHF and UHF versions. A wireless microphone system operating on UHF (or Ultra High Frequency) spectrum is desirable especially in heavy populated urban areas where many VHF wireless systems have been already sold. Both the VHF and UHF systems offer both lapel and handheld microphone versions with the handheld available with either condenser or dynamic microphones.
The UHF system operates between 690 and 725 mHz. carrier frequency with an audio frequency response of 50Hz to 15kHz. The VHF (or Very High Frequency) system has the same audio specs but operates between 174 and 186 Mhz. Frequency stability for both systems measures .005% with less 0.5% third harmonic distortion products. The UHF system is rated at 91dB signal-to-noise ratio with 97dB of quieting while the VHF comes in at 85dB s/n ratio with 91db quieting. (Quieting is a measure of how low in level the undesired background noise inherent in radio transmissions is in relation to the level of the desired, recovered audio signal....higher numbers are better)
Both units come with a warranty that is three times longer than any other system at the same price. Systems are available in eight different stock frequencies and frequency coordination assistance is available from Telex. Telex is located at 9600 Aldrich Avenue South, Minneapolis, MN 55420. You can call them with questions about the ProStar Series at 612-887-5550.
