The U500® Series vocal sets were developed in Germany to bring you affordable professional technology and sound quality. The radio systems for vocals and speech deliver impressive performance and high reliability, which will certainly exceed your expectations. We have designed the range specifically for professional users to ensure that your performance is an impressive and emotional experience.

Selectable transmit power up to 30 mW provides the U500® vocal sets with a free-field range of over 100 metres. They are available in three frequency bands: 584 - 608 MHz and 655 - 679 MHz, where 12 systems can be operated simultaneously, and 823 - 832 MHz + 863 - 865 MHz, where six systems can be operated at the same time. The True Diversity UHF wireless systems are equipped with an automatic scan facility to find the best free frequency, and convenient one-touch infrared synchronisation of transmitter and receiver to facilitate easy set up.

High-contrast OLED displays provide an excellent overview of functions, with indicators for group, channel, radio frequency, and signal strength and battery status. You can even enter individual usernames. In addition to the squelch function, the transmitter’s silent pilot tone ensures fail-safe operation. It protects against interference and mutes the receiver if signals without this tone are present. The U500®’s efficient technology and high-quality components provide clear, distortion-free transmission without latency or artefacts. Low power consumption means that the transmitter can run for up to 10 hours with 2 x AA batteries.

The U500® Series vocal sets are available with hand-held transmitters, headsets, lavalier microphones and single or double receivers. The hand-held transmitters feature interchangeable microphone capsules to suit singing or speaking.
