Power Dynamics PD504H 4X Handheld Wireless Microphone System (568 – 582MHz)

PD-PD504H

The Power Dynamics PD504H is a 4‑channel UHF wireless handheld microphone system that allows you to operate four microphones simultaneously. Each handheld microphone features a dynamic cardioid capsule that delivers clear, detailed sound while rejecting background noise and reducing feedback. The receiver includes colour‑coded channels for easy navigation and individual volume controls. Setup is fast and simple thanks to the one‑button IR sync function, making it ideal for speech, karaoke and general voice applications.

This versatile wireless system operates across a wide 550–585 MHz band with 50 selectable channels. The 10 mW transmitter output and included 1/2‑wave antennas provide excellent operating range. A heavy‑duty carry case with foam cut‑outs is included for safe transport and storage.

This system operates in the 550–585 MHz range, ensuring long‑term compatibility in Australia. To check frequency availability in your area, use the ACMA Channel Finder at http://channelfinder.acma.gov.au/.
