LD Systems LDS-U5047IEMIN Overview

The LD Systems U504.7 IEM HP is a stereo/mono wireless in-ear monitoring system that offers clear monitor mixes with wireless freedom to musicians and presenters performing live on stage. Designed for both pros and beginners, this easy-to-use system marries a set of professional features with a modern design, reliable transmission, and straightforward operation. This model comes with a universal power supply for working abroad. It is well suited for audio applications such as music performances, theater, rehearsals, broadcasts, presentations, houses of worship, and more.

The U504.7 IEM HP includes a 1 RU, 1/2 rack U500 IEM wireless transmitter with its rackmount kit and a U500 IEM bodypack receiver ready to accept the earphones of your choice. The system provides up to 10 hours of continuous use with two AA batteries in the receiver—at a range up to 328'. Up to 12 systems can operate simultaneously in each frequency band.

Tailor the Sound of Your Mix for Clear Audio
  • Use the 3-band EQ with parametric mids and the switchable limiter to keep sudden peaks at bay and ensure that your mix sounds exactly the way you like it.
  • Choose between Stereo, Focus, or Mono monitoring modes. In Mono mode, the two L/R channels are summed. In Stereo mode, the balance between the L/R channels can be adjusted. In Focus mode, the L/R channels are played back in the center and the balance between the two channels can be adjusted directly on the pocket receiver.
  • The bodypack receiver offers a choice of three squelch levels to automatically mute your receiver if you lose reception.
  • With a signal-to-noise ratio greater than 95 dB and with less than 0.3% THD, the system's noise floor is exceptionally low, giving you clear and natural-sounding audio.
Reliable Wireless In-Ear Monitoring at up to 328'
  • The system offers 96 frequencies to choose from, enabling you to find a clean wireless channel at your location.
  • The switchable 2, 10, or 30mW transmission power allows you to overcome interference and reach a maximum range of 328'.
Quick and Easy Setup with Universal Power Supply
