Excellent Audio Function Supporting High-resolution Sources
Released October 2016
Featuring High Quality Sound Technology with High-resolution Source Playbacks
The MDV-Z904W/Z904/Z704W/Z704 integrates Asahi Kasei Microdevices Corporation's (AKM) 32-bit premium audio D/A converter. This DAC is developed with VELVET SOUND technology realizing a high-tolerance design for noise while providing high-resolution 32-bit data processing.
The high-resolution DAC can reproduce even the minutest details in the music including atmosphere that the artist intended by recreating high-resolution sound sources in high-fidelity.
Digital data of non-high-resolution sources are up-converted to higher resolution of 192kH/32-bit digital data by DSP process, and it is played by AKM's 32-bit premium DAC. Not only music source but also video source playbacks can be experienced in high quality sound.
The MDV-Z904W/Z904/Z704W/Z704 adopts AKM's triple core floating point arithmetic DSP for high speed and high accuracy audio signal processing such as sound quality adjustment. This DSP realizes accurate and efficient data processing while achieving high quality sound.
* The MDV-Z904W/Z904 integrates a high-end premium D/A converter, the AK4490. The MDV-Z704W/Z704 integrates a premium D/A converter, the AK4452. And both systems integrate an audio & voice processor, the AK7738.
