Wideband Bodypack Transmitter LINEAR in band 470-663 MHz

MTP40S-USX is an extremely small and light pocket transmitter especially designed for professional wireless microphone applications. Very easy and quick to use thanks to OLED display, dedicated buttons and a joggle selector. MTP40S benefit also of the latest Wisycom RF technology along with an enhanced robustness against noise and inter-modulation.

It benefits of the LINEAR feature @20L power setting: allows EVENLY SPACED frequency allocation intermodulation free

Example for 1 DVBT (6 MHz)

250KHz space -> 25 Mic (narrowband option)
350kHz space -> 18 Mic (wideband)

MTP40S-USX meets the technical requirements for operation in the repacked TV bands and licensed portion of the 600 MHz duplex gap (653-657 MHz), and do not operate in the 600 MHz wireless service band (617-652 MHz / 663-698 MHz).
