Product Description

Main features:

★ All solid-state design, digital analog compatibility;

★ Professional broadcasting level transmitter;

★ All power amplifiers are made of high-power LDMOS tubes produced by PHILIPS;

★ Wideband amplification of power amplifier components;

★ The modulation method is digital DDS modulation

★ Exciter input interface: 2 analog audio interfaces, 1 digital audio interface, 1 SCA/RDS interface, 1 1PPS interface, and 1 10MHz clock interface;

★ Exciter output interface: 1 LOCK IN interface, 1 RS232 interface, 1 RS485 interface, 1 RJ45 interface, 1 RF monitoring interface, and 1 RF power output interface;

The exciter and power amplifier both use a LCD display system, and all are displayed in Chinese;

There are two sound columns on the exciter display screen that fluctuate up and down to display the strength of the left and right channel signals;

The parameters displayed by the exciter and amplifier through the LCD include: emission power, reflection power, current of the amplifier tube, voltage of the amplifier tube, input level, temperature, and loop voltage;

The exciter and power amplifier indicate the above content through indicator lights: power indicator light, overvoltage protection indicator light, standing wave ratio alarm indicator light, remote control status indicator light, temperature alarm indicator light, overcurrent, circuit, overvoltage limit indicator, system communication fault indicator, RF prohibition indicator;

★ Able to set 3 time periods per day to automatically control the power level;

★ Adopting high-efficiency switching power supply;

★ Large screen Chinese LCD display system, capable of computer monitoring;

The entire machine is equipped with various protective measures such as overcurrent, overvoltage, overexcitation, over standing wave, and over temperature.
