High quality sound Advanced AL32 Processing and high precision 32 bit D/A converter Equipped with Advanced AL32 Processing, Denon’s unique analog wave reproduction technology. Reproducibility of weak signals is increased by expanding the 16-bit digital data to 32 bits. Additionally, the unit is equipped with a 192 kHz/32-bit compatible high performance D/A converter for converting the digital data expanded by Advanced AL32 Processing into analog signals. High sound quality operational amplifier + current buffer The unit is equipped with a low noise, high sound quality operational amplifier. The output level features a discrete current buffer circuit for fully driving the headphones. Low phase noise crystal Two low phase noise crystals (22.5792 MHz, 24.576 MHz) are used for the master clock. The crystals remove jitter from the master clock and faithfully reproduce the high resolution sound source by syncing with and switching the sampling frequency. High performance Equipped with a USB-DAC function to support playback of highresolution sound sources This unit supports the playback of high resolution audio formats such as DSD (2.8/5.6 MHz) and PCM files up to 192 kHz/24 bits. It provides high quality playback of high resolution files. GAIN switch Switching the gain enables optimum driving of various types of headphones that have different impedances.
