AKM's AK4495SEQ is a premium, high performance, 32-bit stereo digital-to-analog converter (DAC) that achieves 123 dB dynamic range for stereo and 126 dB for mono outputs (with optional 7 V analog power supply). This is a flagship addition to AKM’s VERITA series of product in the Audio 4 Pro™ family with two channels of AKM’s VELVET SOUND™ technology. An innovative design technique utilizing a symmetrical layout for the left and right channels prevents signal quality deterioration and a 32-bit digital operation block provides full 32-bit processing.

Five digital filters are integrated into the AK4495S providing a choice, making it ideal for a wide range of applications.  The five digital filters that are integrated into the DAC are a short delay, sharp roll-off filter and a short delay, slow roll-off filter for minimum delay, a sharp roll-off filter and a slow roll-off filter for no phase shifting, and an integrated super slow roll-off filter having emphasized characteristics.

The AK4495SEQ supports 2.8 MHz and 5.6 MHz direct stream digital (DSD) input and PCM data input. Volume pass mode bypasses the volume control block and the delta sigma modulator when play back DSD data. It is suitable for applications which have most priority to the sound quality. Since the AK4495SEQ contains an integrated low-pass filter only for DSD data, the required performance in the SACD format book (scarlet book) can be easily realized with a simple external analog filter. The output level is the same for either PCM or DSD input data, as well as for external digital filter input. Volume control is independent of the input data format. Supporting both PCM and DSD audio data, the AK4495S is ideal for high-end audio equipment, including high-end Blu-Ray, DVD-Audio and SACD players, AV receivers, and digital mixers. It is housed in a 44-pin LQFP package.
