Anchor Audio BIG3 Bigfoot 3 Line Array Battery-Powered PA System with Bluetooth

The BIG3 Bigfoot 3 Basic is a powerful, self-contained portable PA system engineered for reliable use in both indoor and outdoor environments. Built to dominate large crowds, it delivers 300W of power through a rugged line-array design featuring five 8" neodymium woofers and a high-efficiency compression driver, producing peak sound levels up to 126 dB. It provides coverage over approximately a 150 x 150 ft area, suitable for up to 2,500 people, depending on the space and acoustics.

This system runs on three internal 12V LiFePO₄ rechargeable batteries, offering over 7 hours of continuous use on a full charge, with a recharge time of approximately 5 hours using standard AC power (100–240V, 50/60Hz).

Connectivity includes:

• 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 BIG3 is designed for one-person setup, with a folding tower array that extends to 72" when open and collapses to 42.5" for transport. Its durable, weather-resistant enclosure includes built-in heavy-duty wheels, making it easy to move between venues.

Note: This base BIG3 model does not support wireless microphones and does not include built-in wireless mic receivers. Wireless microphones cannot be added to this model. For wireless capability, see BIG3 models with built-in AnchorLink receivers (e.g., BIG3-TU4, BIG3-U4).
