Experience digital music to the fullest with High-Resolution Audio. By capturing music at a higher rate than CD, increasing both audio samples per second and the bitrate accuracy of each sample, High-Resolution Audio offers an uncompromised rendition of an artist's music. Savor every breath and subtle movement for a truly emotional experience.
Direct Stream Digital (DSD) playback for High-Resolution Audio
Enjoy studio-quality sound, thanks to the Direct Stream Digital (DSD) audio codec-designed specifically for High-Resolution Audio. This 1-bit format utilizes a stream of very high frequency 1s and 0s to recreate audio waveforms at a higher resolution than conventional codecs. The result is clearer, crisper, High-Resolution Audio quality.
ESS digital-to-analog converter for high performance
The highly acclaimed ES9018S digital-to-analog converter (DAC) makes sure you enjoy distortion-free signal processing and unmatched audio clarity. Powered by its own dedicated power circuit path, and with an unprecedented dynamic range, everything about the ES9018S is optimized to deliver clear, ultra-detailed audio.
Operation amplifier for depth of sound
Enjoy versatile, realistic audio thanks to circuitry from the MUSES 8920E high-end operation amp. Integrated into the RSX-GS9's analog circuits, this component provides authentic depth and detail for everything you listen to, across a wide range of musical styles and genres.
DSEE HX upscaling restores fine detail
DSEE HX (Digital Sound Enhancement Engine) technology upgrades the quality of your compressed music files. When an original music source is compressed, you lose the high-frequency elements in the music. DSEE HX restores them to produce high-quality sound that's closer to the original recording.
Rigid dual-layer chassis for clean, distortion-free sound
The RSX-GS9's chassis boasts four times the rigidity of conventional head units, making sure that external vibrations do not cause distortion. The digital and analog circuits are mounted in separate layers as far apart as possible, preventing the noise that can result from electromagnetic interference and ensuring premium in-car sound quality.
Enjoy pure High-Resolution Audio via front micro USB
Experiencing the highest quality playback on the RSX-GS9 is easy: just connect your High-Resolution Audio capable smartphone or player to the front-facing micro USB port and you're ready to go. This connection makes sure audio signals pass directly through the industry-leading ESS D/A converter, so you can enjoy great-sounding lossless DSD and linear PCM playback.
Sony original capacitors
Designed especially for use in high-end audio products, our premium capacitors provide high-fidelity sound with a bright tone.
Clock generator for high-quality playback
For high-quality sound without compromise. Our 80-MHz, high-precision clock generator sits beside the digital-to-analog converter to reduce vibrations and jitters, improving conversion accuracy and overall audio stability.
Wireless streaming with Bluetooth
Wirelessly stream your favorite tracks with Bluetooth®. Pair your smartphone or tablet with the RSX-GS9 and you can enjoy your music and even control playlists and volume right from your device.
Wide codec support for listening convenience
Enjoy more music freedom, thanks to the RSX-GS9's wide codec compatibility . You can play audio from a host of different file types, compressed or uncompressed, so you can compile the perfect playlist for your road trip.
NFC One-touch for instant connectivity
Near Field Communication (NFC) technology makes complex set-up sequences a thing of the past. Simply touch selected NFC-enabled devices to the on-body N-mark for a quick, seamless connection, then start streaming content via Bluetooth®. No NFC" No problem. You can still manually connect to Bluetooth using your device's settings menu.
Get the most out of Bluetooth® with LDAC
LDAC is a codec developed by Sony for the highest quality Bluetooth® audio streaming. It supports: up to three times higher bitrates than typical Bluetooth® streaming; sampling rates up to 96 kHz; and more efficient coding. The result is superior audio with less compression, enabling better-than-CD quality wireless sound.
