Introducing the Desktop Type Broadcast 4 Channel Balanced XLR Audio to Fiber Optical Converter Extender by Ho-link, a cutting-edge solution for audio transmission that combines advanced technology and user-friendly design. This device allows for seamless transmission of XLR analog balanced audio signals, making it an essential tool for professionals in broadcasting and audio production.

Utilizing CWDM (Coarse Wavelength Division Multiplexing) technology, this converter can efficiently handle one to multi-channel audio transmission. This means you can enjoy the flexibility of sending multiple audio channels over a single fiber optic line, which significantly simplifies your setup and reduces cable clutter.

One of the standout features of this converter is its support for 48V phantom power. Each audio channel is equipped with a switch key that allows users to easily adjust the phantom power according to the needs of the field. This high level of flexibility ensures that you have the right power supply for your microphones or other audio equipment.

In addition to its power capabilities, the converter employs FPGA (Field-Programmable Gate Array) technology along with digital code and clock recovery systems. This integration leads to high stability and reliability during audio transmission. With such technology, you can trust that your audio signals remain intact and clear, even in demanding environments.

Furthermore, the device features automatic high-pass filtering to isolate the DC offset, ensuring that your audio remains clean and free from unwanted noise. Coupled with a high intelligent noise reduction system, it manages soft rising or falling ramp waves and simulated squelch effectively. The impressive 100dB signal-to-noise ratio (SNR) ensures that you experience crystal-clear audio without any popping sounds, which is crucial for professional applications.

The audio interface is designed with a level 3 lightning protection feature, adhering to IEC61000-4-5 standards (8/20μs) with a differential mode rating of 6KV. This means you can use the device with confidence, knowing it is protected against electrical surges that could otherwise damage your equipment.

For those looking for long-distance transmission capabilities, the converter supports a standard single-mode transmission distance of up to 20 kilometers. This feature is particularly beneficial for large venues or outdoor setups where distance can be a challenge.

To keep you informed of the device’s operational status, it comes equipped with an LED status indicator. This allows users to monitor the running status easily, ensuring that you are always aware of the system’s performance.

Designed with simplicity in mind, this converter is plug-and-play. There is no complicated setup required; just connect the devices, and you are ready to go. It is important to note that the devices are used in pairs and are distinguished between transmitter and receiver. This clear distinction helps users avoid any confusion during setup.

In summary, the Desktop Type Broadcast 4 Channel Balanced XLR Audio to Fiber Optical Converter Extender is a robust and versatile solution for audio professionals. With its advanced features, high-quality transmission, and ease of use, it stands out as a top choice for anyone looking to enhance their audio setup.
