Anchor Audio BIG3-U2 Bigfoot 3 Line Array PA System with Dual AnchorLink Wireless Mic Receivers

The BIG3-U2 Bigfoot 3 is a powerful, all-in-one portable PA system designed for large-scale voice and music reinforcement. It delivers 300W of high-output Class-D amplification through a vertical line array of five 8" neodymium woofers and a high-efficiency compression driver, producing peak output levels up to 126 dB. With a coverage area of approximately 150 x 150 ft, it's ideal for crowds of up to 2,500 people, depending on the environment.

This model includes a built-in dual AnchorLink wireless mic receiver, allowing you to pair up to two AnchorLink handheld or bodypack microphones (sold separately). It also features Bluetooth streaming, making it ideal for both spoken word and background music applications.

Powered by three internal 12V LiFePO₄ rechargeable batteries, the BIG3-U2 provides over 7 hours of operation on a full charge, and recharges in about 5 hours using standard AC power (100–240V).

Connectivity includes:

• Integrated dual AnchorLink wireless mic receiver (2.4 GHz digital)
• Class 1 Bluetooth with up to 150 ft range for wireless audio streaming
• Two balanced XLR/¼" combo mic inputs with 48V phantom power (wired microphones only)
• One ¼" line input (Hi-Z compatible)
• One 3.5 mm stereo aux input
• One ¼" line output (pre-fader, isolated, 600Ω) for daisy-chaining to additional systems
• USB charging port (5V/500mA) for mobile devices
  
  

The folding tower array extends to 72" when open and collapses to 42.5" for transport. The unit features a rugged, weather-resistant enclosure with built-in wheels and handles for easy portability.

Ideal for large events, assemblies, sports, or outdoor gatherings where wireless mic capability and portable power are essential.
