500W FM Transmitter 500 Watt FM Radio transmitter radio Stations equipment

Description: 500W FM Broadcast Transmitter· The transmitter implements digital FM modulator module as its core,combining with RF power amplifier.In the transmitter,DSP&DDS are used to execute all-digital processing,such as digital filtering,pre-emphasis,the generation of pilot frequency,stereo coding and FM modulating.A AGC circuit is used to keep the set power stable. · High performance and very good reliability has been proved by the large usage of RS-500W FM transmitters.Also it is low cost and small size. Features: · Hearing similar to CD · All-digital technologies DSP+DDS · Built-in audio signal limiter · Analog and Digital (AES/EBU) audio signal input directly. · AGC circuit can keep the Output Power stability. · Big LCD display all the parameters in real time. · Communication Interface by RS232 for remote · Five kinds of protections for the security · Compact structure FREQUENTLY APPLICABLE USES:1). Community Radio stations2). LPFM radio stations3). City radio stations4). Christian Church radio stations OUTSTANDING FEATURES:1) OVERHEAT PROTECTION: The transmitter will switch to auto-protection with alarm message and a beep sound once the working temperature gets higher than normal range. 2) OVER SWR PROTECTION: SWR is the indication of antenna system connection with transmitter. Once the connection is bad and causing a high SWR Value, the transmitter will switch to automatic protection mode by showing alarm message on the screen with a beeping sound meanwhile. 3) FAN ERROR ALARM When the fan stops running, the alarm message will be displayed on the screen. 4) ADJUSTABLE POWER OUTPUT The RF out of this 1kw FM transmitter is continuously adjustable from 0-500 watt at the stepping of 0.1watt, which means you can tune it to 1w, 1.1w, 1.2w...50w...100w...500W, with just one transmitter you’ll get multiple modes of outputs and easy to tune as per your needs.Product Technical Parameters ：1.Frequency Range : 87.5MHz~108MHz2.Frequency Setting Step : 10KHz 3.Carrier Frequency Precision:±200Hz 4.
