AK4458VN 115dB 768kHz/32-bit 8ch Next Generation Premium Multi-channel DAC Series
2016-04-01 | Return
The AK4458VN is a new generation of premium 32-bit DAC, with 8-channels of AKM’s VELVET SOUND architecture that has been widely adopted by well-established high-end audio companies. This technology realizes fine sound details with its low-distortion architecture in addition to 32-bit resolution digital filter processing. The digital input supports up to 768 kHz PCM and 11.2 MHz DSD (Direct Stream Digital), suitable for high-resolution audio source playback. This premium multi-channel DAC series provides a simple and best solution to wide range of applications with a TDM interface and up to 8-channel variations.
● Dynamic sound play back with large amount of playback information:
- AKMs VELVET SOUND architecture is utilized.
- Low-distortion technology achieves industry’s best performance of -107dB as a DAC with 115dB S/N characteristic.
- OSRD (Over Sampling Ratio Doubler) technology greatly reduces out of band noise.
- IRD (Impulse Response Designed) filters are integrated with 32-bit processing to reproduces detailed natural sound.
- Five different digital filters types are selectable according to the user audio and system preferences.
● Supporting High Resolution Data
- The digital input supports up to 768 kHz PCM and 11.2 MHz DSD (Direct Stream Digital), recreating high-resolution sound that is as close as possible to the original acoustic source.
- It is suitable for high-resolution sound source playback that is becoming popular with Network Audio, USB DACs and Car Audio Systems.
● System Extensibility
2ch/4ch/6ch/8ch lineups provide best sound solution for the system. The digital input supports TDM (Time Division), realizing daisy chain connection. A multichannel playback system such as AV surround receivers and audio interfaces can be easily designed with these premium DACs.
● Maximum Sampling Frequency, Bit Rate: PCM768kHz, 32-bit / DSD256 (11.2MHz), 1-bit
● SNR: 115dB ● THD+N: -107dB ● Sound Color Digital Filter: 5types
