Technical Details – Full Control Across Two Frequency Bands

The LD Systems U508 IEM In-Ear Monitoring System—863–865 MHz + 823–832 MHz consists of a powerful transmitter and a rugged receiver that are perfectly matched. The license-free frequency ranges make the system particularly attractive for bands, mobile acts, and international tours.

The transmitter (LDU508IEMT) offers 96 channels, divided into 8 groups of 12 channels each. It supports three operating modes: Mono, Stereo, and Focus. With an adjustable RF output power of 2, 10, or 30 mW, the system can be optimally adapted to any stage situation—whether it’s a small club show or a large festival stage. The OLED display provides a clear overview of frequency, channel, mode, and audio level. For maximum flexibility, balanced XLR and 6.3 mm jack connectors (combo TRS) are integrated.

A particular highlight is the built-in 3-band equalizer with parametric midrange controls—allowing for precise adjustment of the input signal. In addition, the transmitter features an adjustable headphone output that allows you to monitor the input signal directly. A switchable limiter protects against level peaks, while the three-level squelch ensures a clean sound. The device is powered by a 12–18 V DC power supply and comes equipped with a BNC antenna and a rack-mount kit—for seamless integration into existing systems.

The receiver (LDU508IEMR) is lightweight, compact, and yet extremely powerful. It also offers 96 channels, which can be conveniently synchronized with the transmitter via infrared. The OLED display provides real-time information on the channel, RF signal, and battery status. With a runtime of up to 10 hours on just two AA batteries, the receiver offers exceptional endurance. The output power is 80 mW (at 33 ohms)—enough to be heard clearly even on loud stages.

Controls are located on the side and include buttons for volume, channel selection, and power on/off. The 3.5 mm headphone output is compatible with nearly all standard in-ear headphones. As with the transmitter, the three-level squelch ensures consistently clear signal transmission, even in challenging radio environments.
