AKM introduces a next generation multichannel high-end premium analog-to-digital converter (ADC) with their VERITA AK557X series. The AK557X captures incredible detailed and the true sound expression with its high-resolution 32-bit processing by AKM’s proprietary VELVET SOUND architecture, which has been widely adopted by well-established high-end audio companies. This high-resolution processing and noise tolerance design of the AK557X realize a low distortion recording.
Digital output supports unsurpassed high-resolution sound; up to 768 kHz PCM and 11.2 MHz DSD output is available for the first time as an ADC. This two-, four-, six-, or eight-channel line-up provides a simple and optimal solution to any multichannel system by adopting the flexible TDM interface.
- Dynamic sound recording a large amount of information
- Utilizes AKM’s VELVET SOUND architecture
- Low-distortion technology achieves the industry’s best performance of -112 dB as an ADC with 121 dB S/N characteristic
- Channel summation improves the dynamic range up to 130 dB S/N (AK5578EN:8-to-1 mode)
- Four different impulse response designed (IRD) digital filters types are selectable
- Supports high-resolution data
- The digital output supports up to 768 kHz PCM and 11.2 MHz direct stream digital (DSD), recording high-resolution sound that is as close as possible to the original acoustic source
- It is suitable for high-resolution sound source recording that is becoming popular with network audio and USB DACs
- System extensibility
- Two-, four-, six-, or eight-channel lineups provide the best sound solution for the system
- The digital input supports time division (TDM), realizing daisy-chain connection
- A multichannel system, such as multichannel recorders and mixers, can be easily designed with these premium ADCs
