LD Systems U504.7 HHD Description
The
LD Systems U504.7 HHD brings German-engineered wireless technology to live performers, speakers, and venues needing dependable signal clarity. With its true diversity design and pilot tone squelch, the system minimizes interference and signal loss — even in RF-dense environments.
The included handheld mic features a cardioid dynamic capsule optimized for vocals, delivering a smooth 60 Hz to 16 kHz frequency response. Its shock-mounted capsule reduces handling noise, and interchangeable heads allow for future customization.
An automatic frequency scan makes setup fast and frustration-free, while one-touch IR sync pairs the transmitter and receiver instantly. The OLED screen displays frequency, group/channel info, battery level, and signal strength in real time, making live monitoring simple.
With selectable transmission power (2, 10, or 30 mW), this system adapts easily to small rooms or large stages. Power-efficient circuitry ensures over 10 hours of performance on just two AA batteries.
