Package 2000W FM transmitter complete set include the 2000W FM transmitter, two bay dipole antenna system, 30meters coaxial cable. It is a economic complete package kit for radio station broadcasting.
2000W FM Transmitter Overview
This 2000W FM transmitter adopts the concept of simple design and integrates the exciter and power amplifier, output filter, switching power supply, etc into a 2U high 19-inch standard case. This advanced design reduces the number of connection cables and improves the overall efficiency of the transmitter, making it more reliable and easier to operate.
This 2000W FM Transmitter is 2U 19-inch all-aluminum standard chassis. 3.5-inch LCD display, PLL digital phase-locked loop frequency modulation technology, CD sound quality, the final power amplifier uses high standing wave ratio resistant LDMOS transistors. This 2000W FM transmitter can input analog audio signal or analog modulation signal, and AES / EUB digital signal.
Humanized digital LCD touch panel, simple operation interface with direct touch control.
The integrated LCD displays all system parameters: transmitter frequency, stereo and mono, volume, amplifier tube temperature, audio signal UV meter, forward power, reflected power, modulation mode, and pre-emphasis etc.
2U 19-inch thick aluminum alloy case, which is not only sturdy but also has good heat dissipation.
Precise PLL frequency generation system to ensure the frequency does not drift within at least 10 years.
Built-in high-quality professional stereo encoder.
Excellent power AGC balance control system, the power output can be adjusted from 0 to full power, and has automatic gain power control to maintain the output power within a set range without drifting.
Support external input modulation RDS or SCA signal.
Supports AES-EBU digital signal input, 24Bit 192KHz sampling rate input range, true lossless audio.
Equipped with RS232 communication interface, users can control all operations through the transmitter communication protocol.
RF amplifier uses NXP LDMOS transistor BLF188XR, making it able to withstand severe load mismatch of more than 65: 1 VSWR at 5dB compression point.
Automatically record 9 latest device alarms for later troubleshooting.
