Brax DSP – Output Analog AKM

Brax DSP – Output Analog AKM – stereo analog output module

This analog output module for the modular BRAX DSP is aimed at listeners who prioritise natural, detailed reproduction. It provides one stereo RCA output pair for the CORE Model, is compatible only with that model and is available exclusively as part of the initial configuration, integrated at the factory in Germany.

It pairs the Asahi Kasei AK4490REQ, a 32-bit two-channel high-end D/A converter associated with Velvet Sound technology, with a TI/BurrBrown OPA1656 op-amp with SoundPlus technology in the analog stage, a combination intended for transparent, uncoloured sound.
