Power Dynamics PD504B - 4-Channel UHF Wireless System with Headset and Lavalier Microphones

Power Dynamics PD504B - 4-Channel UHF Wireless System with Headset and Lavalier Microphones

The Power Dynamics PD504B is a four-channel UHF wireless microphone system designed to deliver exceptional sound quality and professional-grade reliability. This comprehensive solution allows for the simultaneous use of four microphones, making it the perfect choice for events, conferences, performances, and presentations requiring multiple speakers or vocalists. Thanks to its advanced UHF technology with PLL oscillator and CPU control, the PD504B ensures stable, clear, and interference-free signal transmission, even in environments with high radio frequency congestion.

Each of the four included bodypack transmitters comes equipped with two microphone options: a headset microphone, ideal for active speakers or fitness instructors who need complete freedom of movement, and a lavalier microphone, perfect for interviews or situations where visual discretion is required. System setup is incredibly simple thanks to infrared (IR) data transmission, which automatically synchronizes the transmitter and receiver channels with the push of a button. The receiver, with its robust metal chassis and 19" rack-mount brackets, is ready to integrate seamlessly into any professional audio setup.
