, product features:
Standard industrial design chassis, aluminum alloy brushed panel, matched with stainless steel chassis
With card holder, transmitting power:,,,, radius is:,-,-, -,-wait.
Frequency - full wideband, standing wave displayed on the panel according to decimal preset frequency band
Temperature protection warning, solid-state frequency phase lock, no frequency drift, power output can be disabled when not locked
Tape reel interface, which can directly play disc content, three sets of line inputs, which can be connected to external decks and decks, and one set of line outputs
Automatic power control, adjustable power, can independently form a simple wireless FM broadcast transmission system ( If point-to-point control is required, additional remote control digital coding is required)
The FM transmitter uses microcomputer phase locking, so the transmission frequency does not drift.
The FM transmitter preamp adopts the most advanced dual frequency-locked subcarrier () remote control coding technology. The frequency is accurate and stable, and the remote control speaker can be turned on and off reliably.
Main selling points:
For wireless FM broadcasting, you only need to connect the transmitter and the transmitting antenna with a feeder, then stand the transmitting antenna at the highest point outdoors, use an FM speaker at the terminal, and connect to the mains power supply to receive the FM broadcast. . Equipment maintenance is also very simple, just test a terminal speaker or front-end equipment. It completely avoids the difficulty of maintenance of traditional broadcasts
It can be placed on telephone poles and street light poles. Firstly, it can reduce the interference of ground waves, geomagnetism, etc. to wireless signals, greatly improving the reception effect. Secondly, it can reduce the damage to equipment caused by human factors. The on/off playback of music is controlled by an encoder, and with the help of a computer and the control software developed by our company, the playback and off time can be set at any time, and the use of sound sources is automatically switched according to the program, truly achieving unattended operation.

Application scope:
As long as the wireless FM broadcast is within the coverage range of the wireless FM signal, it can be received using countless FM receiving amplifiers and FM speakers, and the capacity can be infinitely expanded. It completely solves the problem of difficult expansion of cable broadcasting.
Broadcasting is an important channel for information dissemination. In order to give full play to the communication characteristics of broadcasting, it is necessary to timely disseminate the party’s voice and government orders, disseminate scientific and technological cultural information, satisfy the people’s growing spiritual and cultural life, enhance the transparency of government work, and promote county Economic development is of great significance. Generally speaking, the transmission distance of an FM transmitter is related to the transmitter power, the height of the transmitting antenna, and the local transmission environment (geographical conditions). The wireless FM broadcast system can be widely used in campuses, smart communities, streets, tourist attractions, rural areas, etc. place.

Industry advantages:
Using patch technology and a phase-locked loop frequency synthesis circuit chip controlled by a microcomputer chip, the transmitting frequency is accurate and stable
The transmitting frequency can be changed arbitrarily within the range. Screen display, tap the button to intuitively display frequency and dynamic level
Two sets of microphone input jacks. Wireless FM broadcast transmission is to send audio signals from FM transmitting equipment, and the receiving equipment receives the signals and broadcasts them. The receiving terminal can be combined as needed and broadcast regularly/manually. It can be centralized and unified broadcasting, or it can be broadcast in two or three spots. The broadcasting system is automated and intelligent, allowing centralized control and management of various applications. Can play, tape, and other audio formats. In this process, the loss of high and low frequencies in the line is avoided, so the sound coming out of the FM speaker is loud in treble and deep in bass. The entire sound line is very full, and the sound quality is beautiful and clear
