Item Description

Yggdrasil is a central and deeply revered tree in Norse cosmology. Often referred to as the "World Tree" and sometimes the "Tree of Life," it connects the nine worlds of Norse mythology, forming a cosmic structure that unites everything.

What does this have to do with an amplifier, you ask? If you've missed this, you might not have been paying attention. Our Nordic heritage has always been a core theme in our products. The Zero6 - Yggdrasil amplifier is designed to be the centerpiece of your audio system, capable of powering any B2 audio subwoofer with authority and precision.

While most amplifiers up to 7kW settle for dual oversized 0 GA inputs for power and ground, we don't compromise. Our commitment to enhancing performance for our customers has led us to the logical solution—triples. By incorporating three positive inputs on one side and three ground inputs on the opposite side, all oversized 0 GA, we ensure unparalleled power, connectivity and clean installs.

We started by comparing the YGGDRASILL to the Zero.7, so what's inside and what differs? The design has now become more streamlined due to the Simple Triples layout, but without any compromises in performance. The eight precision-wound toroids in the power supply further increase efficiency and power output. Dynamics are managed by a capacitance bank of 15,000 uF, which is comparable to the Zero.7. The more compact layout has nearly shaved off 4 inches / 10 cm in length compared to its predecessor, making the Zero6 - Yggdrasil a very potent amplifier with a power output that surpasses that of its predecessor.

The ACCU8 eliminates the guesswork from setting your crossovers. The 41 click pots each correspond to a unique frequency, ensuring precise audio settings. The clip indicator, which is dead-on accurate with standalone tools, provides full control over your signal path.

Additionally, the daisy chain with gain, slave, and master functions is a first in an amplifier of this level. It gives you the ability to either strap two amplifiers together or run a near-infinite number of amplifiers in a daisy chain, all with full control from the master.
