The FEUR FU-4.200 DSP UHF is a four channel UHF wireless microphone system with an integrated digital signal processor, 4 x 50 selectable channels, infrared carrier-frequency sync, unique ID addressing and automatic non-interference frequency search. It is built for conferences, worship services and productions running four wireless sources at once in a crowded RF environment.
Four channels of wireless that stay put when the building fills with competing signal.
Every microphone you add to a wireless system multiplies the ways it can fail. Four transmitters in one room is where amateur gear starts dropping out, and it is exactly the point the FU-4.200 DSP was designed for. The onboard digital signal processor manages the signal path continuously, holding stability and suppressing artifacts before they reach the console.
Automatic non-interference frequency search scans and lands the system on clean frequencies instead of asking you to guess. Unique ID addressing assigns each transmitter its own identity so that a second system in the next room cannot cross into your channels. Advanced anti-jamming circuitry handles the rest.
Infrared carrier-frequency sync pairs each transmitter to its receiver channel in seconds, and high and low transmission power settings let you dial RF output to the room instead of blasting a small space at full power and creating your own interference.

| Product Type | Professional Wireless UHF System |
| Channels | 4 x 50 UHF channels |
| DSP | Integrated digital signal processor |
| Synchronization | Infrared carrier-frequency sync |
| ID System | Unique ID address |
| Frequency Search | Automatic non-interference scan |

How Many Channels Does the FU-4.200 DSP Have?
Four independent wireless channels, each selectable across 50 UHF frequencies, for 4 x 50 total. All four run simultaneously.
Who Is the FU-4.200 DSP For?
Anyone managing four wireless sources at once. Conference AV, houses of worship with a full platform team, theater, corporate events, education and broadcast. If you have outgrown a two channel system, this is the next step.
What Does the DSP Actually Do?
It manages signal behavior continuously through the transmission path, holding stability and reducing unwanted artifacts before they become audible. In practice it is the difference between a system that sounds fine in an empty room and one that still sounds fine with four transmitters live and an audience in the seats.
How Does the System Avoid Interference?
Three ways working together. Automatic frequency search finds clean channels, unique ID addressing keeps transmitters from crossing into the wrong receiver, and anti-jamming circuitry handles interference that gets through. Adjustable transmission power lets you keep RF output proportional to the room.
What Comes in the Box?
A four channel UHF receiver, the transmitters specified for this model, battery and charger per model, and the user manual. Call 844-687-4208 to confirm handheld versus bodypack configuration before you order, since FEUR varies package contents by region and channel.

Why FEUR?
FEUR was founded in Germany by a team of engineers and sound specialists who set out to make professional audio equipment that performs at a high level and stays within reach of the people who actually use it every week. Where most of the industry aims either at high-end studio work or at the bottom of the market, FEUR builds for the working middle: independent artists, houses of worship, schools, mobile operators and installed systems that need gear to show up and work every week.
