B5DH217Wireless Micro Transmitter

Preliminary Users Manual, Telex FMR-1000 System. Telex Model FMR-1000 Wireless Microphone Receiver. Telex Model WT-1000 Wireless Beltpack Transmitter. Telex Model HT-1000 Wireless Handheld Transmitter. The components above form the Telex “1000” Professional Grade Wireless Microphone System. The system is designed to be used in professional installations where Sound Quality and Reliability are of prime importance. Auto-set features and simplicity of operation are assured along with flexibility for varying venues. These features save valuable installation time at the outset and in the future to help prevent “recalls”.

Telex Model FMR-1000 UHF Wireless Microphone Receiver The Telex Model FMR-1000 Receiver is a 950 Channel, frequency-selectable full diversity system operating within the frequency range of 520.0 to 746.0 MHz, on specific pre-set bands of frequencies with designated systems for UHF Television Channels . This configuration allows some operation even if several TV channels are in use locally. If any of the TV channels are some distance away from the area where the FMR-1000 is to be used, some of the FMR- 1000 channels can also be used in those channels , with some risk of minor interference. Channel spacing has been computer calculated and programmed to minimize interference. Systems of FMR-1000 and its companion transmitters are capable of operating on at least 5 sets of frequencies in a single TV channel simultaneously, sometimes more depending on the individual venue. Certain frequencies can be combined to form a system of 16. Digital frequency control of the FMR-1000 permits flexibility within a given area and assures confidence in the equipment capability.
