Move freely on stage while the perfect monitor mix is delivered directly to your ears: the amazing performance and reliability of the U500® In-Ear Monitoring Systems will surpass your expectations for certain. Designed with the pro user in mind, they feature advanced technology, contemporary looks and straightforward operation.
U500® In-Ear Systems provide a selection of 96 channels and 2, 10 or 30 mW RF output power for a transmission range greater than 100 m. For quick and trouble-free setup, they allow for convenient infrared synchronisation of transmitter and receiver. U500® In-Ears sport high-contrast OLED displays and allow for individual user name assignment. In addition, you can save 10 custom presets.
To deliver pristine, precise audio U500® In-Ear Monitoring Systems include a 3-band EQ with parametric mids, a switchable limiter and a squelch circuit. They offer a choice of stereo or mono operation and a direct monitoring headphone output at the transmitter. They offer a choice of stereo or mono operation and a direct monitoring headphone output at the transmitter. With a signal-to-noise ratio greater than 95 dB and less than 0,3% THD, the U500® In-Ear's noise floor is exceptionally low.
Drawing little current only, the U500® Bodypack Receiver operates up to 10 hours on two AA batteries. A volume control allows convenient in-performance monitoring level adjustment. Three selectable squelch levels ensure optimum performance at all times.
U500® In-Ear Monitoring Systems are available for operation in five frequency ranges. The 470 - 490 MHz, 514 - 542 MHz, 584 - 608 MHz and 655 - 679 MHz bands permit running up to 12 systems simultaneously. In the 823 - 832 MHz + 863 - 865 MHz range six systems can be operated at the same time providing wireless monitoring for your entire band.

We have developed the wireless U300® in-ear monitoring systems for unlimited freedom of movement on the stage with perfect in-ear monitor sound at all times. Developed in Germany, their clear, modern design and straightforward operation make them the perfect choice – not just for beginners. Their reliable range of up to 100 m and their low-reaching frequency band of 50 Hz to 16 kHz ensure professional performance. U300® in-ear sets are available for operation in 5 frequency bands: 584 MHz - 608 MHz, 655 MHz - 679 MHz, 823 MHz - 832 MHz+ 863 MHz - 865 MHz, 470 MHz - 490 MHz or 514 MHz - 542 MHz. Six systems can be used simultaneously in each case.
The U300® in-ear transmitters offer a choice of 12 transmission channels and an RF transmission power of 10 mW. They can also be operated in mono or stereo mode. Combo sockets serve as symmetrical XLR and asymmetrical 6.35 mm jack inputs. Left and right input levels can be controlled separately, while two LED chains indicate audio signal strength.
The U300® bodypack receiver has a mini jack socket to connect the earphones as well as displays for channel, stereo mode and low battery status. Running on two AA batteries, it has an operating time of 10 hours. A practical controller allows individual adjustment of the monitoring volume during performance. 19" rack assembly kit included.
