BRAX GX2000
 
With our first BRAX amplifiers, the X2000 & X2400, we set a milestone in the history of high-end car audio. Now, the brand new successors BRAX GX2000 and BRAX GX2400 ignite an exciting new era of audiophile innovation. Both amplifiers combine elegant, puristic design with state-of-the-art Class AB technology.
 
This generation comes without any crossovers and filter functions. The sophisticated layout of the circuit board combined with short signal paths and handpicked components “made in Germany” ensure a pristine listening experience and underline the puristic design as well as the high-end philosophy of the amplifiers and the most discerning of audiophiles.
 
To achieve our high quality requirements, we only use hand-selected transistors for the production of each GX-amplifier in order to avoid even the smallest power variations, in turn, we can eliminate the need for manufacturing tolerances, perfection is the only tolerance accepted. The transistors are subject to placement in more than 300 categories; this is possible because of in-house developed measuring equipment, it really is that important to us!
 
In addition, the solid terminals that are gold-plated will accommodate cables up to 50mm², as well as a separate terminal for connecting a BRAX IPC Capacitor directly to the switching transistors. Put simply, the GX2000 and GX2400 can only described as truly high-end amplifiers, for precise and natural sound reproduction.
 
Each amplifier is available in black or silver finish, either with a short or extended heatsink.
 
Start-Stop capability
The switched power supply of the HELIX C FOUR assures operation even if the battery’s voltage drops down to 6 Volts during engine crank.
 
High-Resolution audio
The extremely broadband audio bandwidth of the amplifier ensures a lossless audio reproduction of High-Resolution audio content to provide the best possible sound in studio quality.
