Give Four Performers Their Own Wireless Microphone at Once

The AU400 combines four fixed UHF channels, four handheld microphones and a metal receiver for panels, karaoke groups, classrooms and hosted events.

Debra Audio AU400 4-Channel UHF Microphone System – 4 Handheld Mics

Why It Helps

  • Four receiver channels let four handheld microphones operate simultaneously.
  • Dedicated hardware reduces the need to pass one microphone around a group.
  • Metal receiver is designed for fixed event and PA setups.
  • Squelch circuitry helps suppress output when a usable transmitter signal is absent.
  • Supplier-stated long open-space range supports larger rooms when conditions allow.

Product Details

  • Model: Debra Audio AU400.
  • Includes one wireless receiver and four handheld microphones.
  • This live variant is specifically the four-handheld “A frequency” set; lavalier and headset microphones are not included.
  • A-frequency points listed as 501, 511.5, 524 and 538.5 MHz.
  • Supplier-stated line-of-sight range: up to approximately 300 ft (91 m).
  • Exact output connections, power accessories, microphone battery type and full package contents are not verified in the extracted source.

Quick Setup

  • Before purchase or use, confirm all four fixed frequencies are lawful and suitable in Australia at your location.
  • Connect the receiver to a compatible mixer or PA with appropriate cabling and start with all channel volumes low.
  • Fit suitable batteries, power on microphones one at a time and test every channel before the event.

Care & Safety

The old claim that these frequencies can be used worldwide is incorrect. Wireless spectrum rules are country- and location-specific; confirm current ACMA rules, especially for fixed 501–538.5 MHz channels. Do not use if local services occupy them. Open-space range is not guaranteed indoors. Keep receiver and power equipment dry.
