Description

Premium SRCs Premium SRC AK4136
VELVET SOUNDThe AK4136 is a 2ch digital sampling rate converter (SRC). The input sampling rate ranges from 8kHz to 384kHz. The output sampling rate is from 8kHz to 384kHz. The AK4136 has an internal Oscillator. Therefor it does not need any external master clocks and simplifies a system configuration. The AK4136 is suitable for the application interfacing to different sampling rates such as Automotive Audio Systems.

● Dynamic sound playback with large amount of playback information

- AKMs VELVET SOUND architecture is utilized.
- Low-distortion technology achieves industry’s best performance of -140dB as an SRC with 176dB D/R (A-weighted) characteristic.
- IRD (Impulse Response Designed) filters are integrated with 32-bit processing to reproduces detailed natural sound.
- Four different digital filters types are selectable according to the user audio and system preferences.

● Supporting High Resolution Data

- The digital input supports up to 384kHz PCM, 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 and USB DACs.

● Sampling Rate Conversion

- The AK4136 supports a PCM to PCM format sampling rate conversion.
