Item Description

Yggdrasil, the legendary World Tree of Norse mythology, connects all realms with unmatched strength and precision. Inspired by this symbol of power and unity, the Zero6 - Yggdrasil amplifier is designed to be the cornerstone of your audio system, effortlessly driving any B2 Audio subwoofer with authority.

Most amplifiers up to 7kW rely on dual oversized 0 GA inputs for power and ground—but we went further. The Zero6 features triple positive and triple ground inputs (all oversized 0 GA), delivering unrivaled connectivity, cleaner installs, and maximum power transfer.

Compared to previous designs, the Zero6 has been refined with a Simple Triples layout, streamlining the internal architecture without sacrificing performance. Eight precision-wound toroids in the power supply boost efficiency and output, while a 15,000 uF capacitance bank ensures tight, responsive dynamics. The compact design shaves nearly 4 inches (10 cm) off its predecessor’s length, making the Zero6 as space-conscious as it is powerful.

Fine-tune your system with the ACCU8, which removes the guesswork from crossovers. With 41 click pots mapped to precise frequencies and a highly accurate clip indicator, you have full command over your signal path.

The Zero6 also introduces master/slave daisy chain functionality, letting you connect two—or virtually unlimited—amplifiers in series while controlling everything from a single master unit. This innovation gives you unprecedented flexibility for multi-amplifier setups.
