G-MARK Dual-Channel UHF Wireless Microphone System

Give Two Speakers or Singers Their Own Wireless Channels

A mains-powered receiver, two UHF handheld microphones and independent volume controls make it easier to balance two voices for karaoke, presentations or events.

Why It Helps

• Two UHF channels allow both handheld microphones to operate at the same time.
• Independent volume controls help balance quieter and louder voices.
• Automatic scanning and IR synchronisation help locate and pair a less-congested frequency.
• Twin receiver antennas support stable line-of-sight operation.
• 6.35 mm audio connection suits many mixers, PA amplifiers and powered speakers with microphone-level input.

Product Details

• Selectable frequency range stated as 520–580 MHz.
• Supplier-stated line-of-sight range: approximately 200–250 ft (61–76 m); walls and interference reduce range.
• Includes receiver, two UHF handheld microphones, 6.35 mm audio cable, power adapter, two antennas, two anti-roll rings and manual.
• Microphone battery type and inclusion are not specified in the extracted source.
• Receiver must connect to a compatible MIC input—not an AUX input.

Quick Setup

• Confirm the supplied frequency range is lawful and suitable at your location and that your sound system has an appropriate microphone input.
• Attach both antennas, connect the receiver with volumes low and power it using the supplied adapter.
• Fit suitable batteries in the microphones, switch on, auto-scan/IR-sync if needed, then raise each channel gradually.

Care & Safety

Australian wireless-frequency availability can change and some spectrum is licensed; confirm current ACMA requirements before professional or public use. A claimed open-air range is not guaranteed indoors. Keep the receiver and power adapter dry, route cables safely, and position microphones behind speakers to reduce feedback.
