The CZE-7C is a powerful and compact FM signal jammer that transmits FM signals in the range of 76 to 108MHz, and can effectively “block” radio stations operating in the same frequency band within a radius of up to 100 meters. The ideal coverage range is a radius of 3 kilometers (if there are no other radio stations operating on the same frequency, it can also be used as your own radio station to play your favorite audio)
The device is made of high-quality aluminum casing and equipped with a blue backlit LCD to display the five-digit frequency. Equipped with BH1415F chip, it is a new generation of digitally controlled FM stereo radio chip from ROHM, with built-in limiter and low-pass filter circuits to ensure better sound quality.
The control board is designed with a high-performance STC series microcontroller, with performance far exceeding AT89C2051, with microphone and amplifier audio inputs, adjustable input level, and flexible switching of transmission power between 1W and 7W.
The suppressor is powered by a 220-volt power grid, ensuring long-term stable operation.
Product features include:
- Suppresses FM signals with any frequency in the range of 76-108MHz;
- Quickly finds the target frequency function;
- Supports smartphone or microphone connection to play music;
- Adopts Japan’s ROHM BH1415 chip to ensure high-fidelity and high-stability signal transmission;
- Clear stereo sound quality and enhanced telescopic antenna;
- Excellent heat dissipation performance (there is 1 fan in the chassis) and easy-to-use LCD display for frequency and volume adjustment;
- With flexible frequency range adjustment function, microphone and volume control make operation more convenient.
