Description
The LD Systems U504.7 BPH (USA Version) is part of the advanced U500® Series, engineered in Germany to deliver professional-grade wireless performance for vocals, speech, presentations, and live events. Designed for reliability and clarity, this UHF True Diversity system offers stable signal transmission, premium audio quality, and effortless setup—ideal for professional users who demand consistency and precision.
Featuring selectable transmit power up to 30 mW, the system provides a free-field range of over 100 meters, ensuring freedom of movement on stage. The automatic frequency scan identifies the best available channel, while one-touch IR synchronisation seamlessly pairs the transmitter and receiver for fast, trouble-free configuration.
High-contrast OLED displays on both transmitter and receiver offer clear visibility of channels, groups, RF strength, signal status, battery life, and even support custom usernames. A built-in silent pilot tone and squelch function ensure fail-safe operation by preventing interference and muting unwanted signals. With low power consumption, the bodypack transmitter runs for up to 10 hours on AA batteries, making it dependable for long performances.
The U504.7 BPH system includes a bodypack transmitter, dual true-diversity receiver, and a cardioid headset microphone for clear, stable, and distortion-free voice reproduction without latency or artifacts.
