Product file
MTH400 is a handheld transmitter especially designed for professional wireless microphone applications. It is very easy and quick to use thanks to OLED display and 1 joggle selector and 2 buttons for straight setup of gain and channel. MTH400 benefits also of the latest Wisycom RF technology, it has been especially designed for robustness against noise and self-interference thanks to a special intermodulation cancellation circuit.
Frequency ranges B5 option: 470 ÷ 654 MHz
B3 option: 510 ÷ 698 MHz
B2 option: 566 ÷ 798 MHz
Switchable channels 2400 managed in 40 groups ofr 60 frequencies completely user customizable
Switching-window Up to 232 MHz, depending on band (see Variants below)
Frequencies Quartz PLL frequency synthesizer circuit (25 kHz step)
Frequency error ± 2.5 ppm, in the rated temperature range
RF Power switchable typ. 10 mW / 50 mW /100 mW
note: in some countries high power can be disabled, for local norm!
Modulation wideband FM, with pre-emphasis
Nominal deviation ±40 kHz
Peak deviation ±56 kHz
Spurious emissions < 2 nW
Telemetry feature TX transmits also a digitally modulated sub-carrier, suitable for:
