The Zero1 will blind you with its presence & appearance.
The entire Zero line has always been about amps setting new standards in terms of power, performance & prestige.
With the Zero1/Zero.5 we resurrected a project started in 2008, where the intention was to show the idea of compact power, but without any compromises.

The goal was clear, make an amp that could be used in the toughests competition formats, and then driven home from the show with flawless daily performance. In order to accomplish this, only the finest materials were chosen, hand picked & matched premium grade components from the worlds best suppliers.

As with all of our amplifiers, efficiency is a key feature. So even with the small footprint (18.9″ /48 cm), the heatsink from the reveered and feared M series was chosen to avoid thermal issues. Furthermore, it takes power to make power. Naturally we opted for a dual 0 GA power & ground input to ensure the 3 Oz pcb had the juice to deliver 5 Kw of power (@ 15v – <5% THD).

But as with any habit, you may need more, so we implemented the Slave1 / Slave2 function (2011 feature). This enables you to strap amplfiers to double the power, or merely link one amp as master with multiple slaves being controlled by the master gain!

*In order to get the full power output of the amplifier, it is crucial that your electical system is correctly (over) dimensioned. Failure to upgrading will constrain the power output & lower the efficiency which can cause damage to the amplifier & void the warranty, this also includes ohm loads below of what is written in the manual. Do take your time and read the manual thoroughly before installing!
