Narrow band professional multi channel receiver 70RX-T1

The 70RX-T1 is a professional FM narrow band multi-channel radio receiver according to EN300113. Compared to the predecessor 70RX-T the height was reduced by 35%. In combination with our transmitter modules a long-range radio system can be set up in simplex or half duplex mode.

In addition to the standard frequencies in the European ISM band at 433 / 434 MHz, filters are available for the world's most popular frequencies in the 400 MHz band. Due to the bandwidth of the filters, a wide range can be covered with only a few variants. Currently, filters are available for 406 - 418 MHz, 418 - 428 MHz, 428 - 438 MHz, 438 - 448 MHz, 456 - 466 MHz and 466 - 476 MHz. Please ask us for your desired frequency.

The frequency setting is easily predefined for the user in multiples of the channel raster. Therefore, complex programming of the receiver module is not necessary. A DIP-switch or simple soldering bridges are sufficient. The internal microprocessor generates a serial data protocol out of the 8 bit parallel data word which sets the synthesizer. Up to 256 channels can be pre-programmed on customer request.

High-current mixers and complex crystal filters provide the 70RX-T1 with an extraordinarily high selectivity and interference immunity, which enables the operation of many devices in close proximity to each other in terms of spatial and frequency. The outstanding sensitivity for a professional receiver allows signal transmissions over very long distances. 10mW output power of 70TX-M1 or 70TX-S together with the remote control unit FSM24 is f.e. sufficient for a free field range of more than 1800 m.

The direct audio signal output doesn`t restrict its use for any kind of coding. Any type of recommendable signal can be used, even analogue audio signals, e.g. speech. A Butterworth filter at the output eliminates noise- and interfering signals with high efficiency.
