30W FM transmitter(DSP+DDS digital technology )
INNOVATIVE PROFESSIONAL FM TRANSMITTER USING ALL-DIGITAL TECHNOLOGY.
New digital signal process(DSP) technology. Direct digital synthesis frequency(DDS)technology. Advanced MCU control system. Columnar dynamic display audio signal. Perfect audio effect of CD sound. Wide range audio input level. AES/EBU standard digital audio input directly. The standard frequency of RF output is 87.00-108MHz with the step of 10kHz(other frequency cab be ordered).
Electric control AGC controls the zero deviation of output power. LCD can synchronously display the work parameters. Unique menu design of Chinese/English view page. RS-232/485 serial communication remote control and telemetering. 2U, 19-inch standard chassis structure.
