High-end 4-channel amplifier
Based on our principles, "handmade" and "Made in Germany", we have set ourselves the goal of developing high-end amplifier of the top class to compromise with the latest technical knowledge. The NOX4 and NOX4 DSP are both results of technological excellence and a true high-end statement: Years of development, innovative technologies and an extremely fastidious production in combination with the love of music as a driving force for our work to make the BRAX NOX amplifiers undoubtedly sounded the most powerful four-channel amplifiers in the world.
The linear design of the NOX amplifiers and down to the last detail, the board layout, we have developed two variants aware. When NOX4 is no need to use crossovers and filter functions. Short signal paths ensure, in combination with selected components "Made in Germany" as unadulterated music enjoyment and emphasize the puristic high-end philosophy of BRAX.
The expanded version NOX4 DSP offers uncompromising settings via the integrated 6-channel audio DSP. It allows not only the 4 internal channels set free, but also the two line-out outputs.
To manufacturing tolerances and performance differences between individual components to eliminate completely, we will use for the production of each individual amplifier NOX exclusively hand-selected transistors, which are divided into more than 300 categories. They can be abgestimmet perfectly. In this way, global reach BRAX amplifier reference status.
The switching power supply of the BRAX NOX4 is a captivating combination of technology and hand-made, selected components. Furthermore, in order to directly regulate voltage fluctuations on the power supply can have the amplifier input jacks for use specifically on a buffer capacitor. The gold-plated, solid power terminals to accept cable with a diameter up to 50mm ² and also make an important contribution to the optimal power supply for the BRAX NOX4.
As a result, traces the BRAX NOX4 by a highly dynamic, lightning fast and powerful sound reproduction. Rounding out the final stage of the underlying philosophy of the package in a wooden crate. In addition, each unit is individually produced and recorded with the corresponding serial number in our database service. We produce the BRAX NOX4 exclusively to order, while focusing always happy to special customer requests. Thus, each stage is allowed to decorate a unique piece, the "high end made in Germany" to law with the title.
