1 x analog input module with AKM converter
Precise A/D conversion for maximum musicality
The BRAX DSP – Input Analog AKM module provides two analog stereo inputs, selectable via RCA or highlevel. Thanks to the continuously adjustable input sensitivity from 1 to 8 volts (RCA) or 3.5 to 30 volts (highlevel), the module can be precisely matched to the output voltage of the connected signal source. This ensures optimal level adjustment and, as a result, the best possible sound quality.
At the heart of the module is the AKM AK5572EN – a high-end 32 Bit, 2-channel A/D converter with Velvet Sound technology, enabling an unaltered and highly detailed conversion of the original signal. It is complemented by the high-quality LME49720 Dual High Performance OpAmp from Texas Instruments, ensuring maximum precision in the analog signal path.
Four software-configurable digital input filters with selectable characteristics provide additional options for sound tuning. The highlevel input is also equipped with the ADEP.3 circuit, which reliably bypasses radio diagnostic systems. In addition, the module features an Auto Turn-On function, allowing the DSP to be switched on automatically via the highlevel input.
Important: The BRAX DSP – Input Analog AKM module is available exclusively as part of the initial BRAX DSP CORE Model configuration and is integrated at the factory – Made in Germany.
