Technical Details and System Components at a Glance

The LD Systems U505 IEM HP set consists of a transmitter, a portable receiver, and professional in-ear headphones. All components are optimally matched to each other and deliver a monitoring experience of the highest caliber. Wireless transmission operates in the 584–608 MHz frequency range, where up to 12 systems can be operated simultaneously—perfect for bands or stage productions with multiple musicians.

The transmitter (LDU505IEMT) supports 12 channels and can be operated in mono, stereo, or focus mode. The RF transmit power can be flexibly adjusted to 2 mW, 10 mW, or 30 mW—depending on the required range and interference conditions. A 3-band EQ with parametric midrange control allows for precise sound shaping, while a switchable limiter provides additional hearing protection. The signal-to-noise ratio of 93 dB and a total harmonic distortion of less than 0.3% guarantee clean signal transmission. Balanced XLR and 6.3 mm jack inputs are available for connecting audio sources. Thanks to the OLED display and intuitive menu system, operation remains convenient even under live conditions.

The receiver (LDU505IEMR) features a lightweight and compact design that can be worn discreetly on the body. It also offers 12 channels that can be quickly synchronized with the transmitter via infrared. The frequency response of 40 Hz to 16 kHz ensures detailed and natural reproduction of the monitor signal. The maximum output level is 80 mW (at 33 ohms impedance), which ensures clearly intelligible monitoring signals even in loud environments. Two AA batteries provide up to 10 hours of battery life. Thanks to the OLED display, battery status LED, and controls for volume and channel selection, users always have full control.

The headphones (LDIEHP2) are dynamic, with an impedance of 32 ohms and a frequency response ranging from 20 Hz to 18 kHz. Their lightweight design—weighing just 22 grams—ensures exceptional comfort, even during long shows or rehearsals. The included silicone and foam ear tips in three sizes offer a perfect fit for every ear shape and optimal isolation from external noise. A sturdy carrying case reliably protects the headphones during transport.

Why the LD Systems U505 IEM HP Is a Worthwhile Investment

The LD Systems U505 IEM HP is designed for musicians and sound engineers who refuse to compromise. The system’s tremendous flexibility—thanks to various operating modes, an EQ for sound shaping, the ability to directly control the signal at the transmitter, and high-quality headphone features—makes it a true professional tool. Its ease of use—thanks to OLED displays, user-definable presets, and IR synchronization—saves time and reduces potential sources of error during live performances.

The system offers the highest audio quality combined with low power consumption and a rugged design. With a selection of different transmit power levels, the U505 IEM HP can be flexibly adapted to various stage conditions. The ability to operate up to 12 systems simultaneously makes it ideal for larger productions or bands. Thanks to the included rack-mount kit and accessories, the system is ready for immediate use and can be easily integrated into existing racks.

For those who value professional audio quality, reliable technology, and thoughtful design, the LD Systems U505 IEM HP is a future-proof solution for perfect monitoring on any stage.
