Welcome to add my skype to get more details:Jacky.shineco
Outline
SNK-7313-I (500 Watt) is Shineco’s newest generation of FM audio transmitter with low and medium power. It adopts advanced third generation of FM modulation technologies: digital signal processing (FPGA) and digital frequency synthesis technology (DAC). SNK-7313-I takes use of the advantage of digital audio processing technology to provide users a CD quality hearing experience with high linear and high gain LDMOS tube amplifier module.
Key Features
* Fully complying with national standard (GB/T4311-2000) and industrial standard (GY/T169-2001)
* Adopt high gain and high linear LDMOS tube amplifier module design
* Adopt international advanced digital signal processingtechnology (FPGA) for audio encoding
* Support AGC function with sustained power output (±0.1dB) to ensure the transmitter a good stability and reliability
* Adjustable output power as needed (25W~500W)
* Low power consumption and super linear design to improve the transmission power, and reduce the nonlinear distortion
* LED on the front panel supporting alarm and signal monitor
* High-efficiency power supply with wide range of voltage (AC100~264V), suitable for different working condition
* Equiped with multiple lightning protection measures
* Support fault self-diagnosis and self-protection
* Air-cooled system with low consumption and low noise
* Multi lightning protection measures, good protection for whole equipment
* Full digital front panel control, easy operation
* 24-hour working unmanned, user friendly design
* Two Transmitters can be connected simultaneously by Coaxial switch, and one for back up
