Description BRAX DSP – The Pinnacle of Digital Sound Processing Overview The BRAX DSP represents the ultimate in digital sound processing, developed over seven years from its inception in 2011 to release in late 2018. This groundbreaking product is the most sophisticated DSP ever created by Audiotec Fischer, setting new standards in sound quality, modularity, and engineering excellence. Equipped with three ultra-powerful 64-bit Sigma350 DSPs, the BRAX DSP delivers 3.6 billion MAC operations per second, operating natively at 192 kHz and offering audio bandwidth up to 80 kHz. Combined with Asahi Kasei’s industry-leading “Velvet Sound” converters, this DSP is designed for the most demanding audiophiles and professional installations. Key Features Three Sigma350 64-bit DSPsProcessing power of 3.6 billion MAC operations per second for real-time, high-resolution performance. Asahi Kasei A/D and D/A Converters32-bit "Velvet Sound" converters deliver outstanding signal-to-noise and THD performance. Native 192 kHz Sample RateEnsures ultra high-resolution sound with frequency response up to 80 kHz. Modular I/O ConceptConfigure 8-channel input / 12-channel output via analog (RCA/Highlevel) or digital (SPDIF optical/coaxial) modules. Output Sampling Rate SelectionSwitchable between 48 / 96 / 192 kHz for flexibility in system design. DiSAC Volume ControlLossless, analog volume control in conjunction with the BRAX MX4 PRO amplifier. Advanced Control CoProcessor (ACO)Manages all operations and enables high-speed communication and setup switching. 55 Voltage RegulatorsEnsures ultra-clean power supply and start-stop capability. Solid Mechanical DesignCNC-machined aluminum housing, massive heatsinks, and solid-milled RCA jacks showcase unparalleled build quality. Exclusive DSP Sound Features RealCenterCreates a dynamically controlled center image for an immersive stereo field that remains balanced for both driver and passenger. Augmented Bass ProcessingIncludes: Dynamic Bass Enhancement: Adaptive bass gain with subsonic filter management. SubXpander: Adds subharmonic tones for richer, deeper bass. StageXpanderSignificantly increases stereo width without compromising localization accuracy. ClarityXpanderEnhances high-frequency detail and brilliance, with adjustable levels for front and center channels.
