About the Sony RSX-GS9
Audiophile sound for the automotive enthusiast
Audiophile sound for the automotive enthusiast
If you're into digital music, you're probably used to settling for "lossy" sound when you play your favorite tunes in the car. Well, you don't have to settle anymore. Sony's High-Resolution Audio system lets you enjoy the songs you love in all the glorious detail the artists intended. The system includes this RSX-GS9 receiver, plus speakers, amps and subs (sold separately or in packages - see below) that are designed to work together to produce stunning, audiophile-quality sound in your car.
Superior components and construction
Designed for the serious audiophile, Sony's RSX-GS9 hi-res digital media receiver brings true high-resolution performance to the automotive environment. The digital and analog sections live in two separate layers inside an incredibly rigid chassis, so noise caused by vibration and interference is virtually eliminated. Sony uses superior components found in their high-end home audio products to ensure that your music is delivered with the highest possible fidelity. You'll hear your music with all the clarity and punch you expect, whether your hi-res files are on your phone or a compatible media player (like a Sony Hi-Res Walkman).
A system designed for serious listeners
The RSX-GS9 will play a vast array of digital file types, including WMA, MP3, AAC, FLAC, and DSD. High-res files will sound as wonderful as you expect them too, but you'll also be amazed at what Sony's Digital Sound Enhancement Engine does to your old, non-high-res tunes. They won't sound totally high-res, but they'll still sound better than ever after the receiver automatically upscales them for you. You can even adjust the time alignment to create the ideal sound stage for your vehicle.
This premium digital-to-analog converter translates your files with unerring accuracy.
The RSX-GS9 works with Apple® or Android® smartphones, so you can play your music using the built-in Bluetooth®, NFC, or Sony's SongPal app, which lets you browse a wide variety of streaming services. SongPal also lets you control your receiver's settings from your phone. You can plug your iPod, iPhone, or Android phone into the receiver's front USB input for direct control and playback of your music.
Sony's High Resolution Audio System
This audiophile-quality receiver is just one part of Sony's impressive High Resolution Audio System. It's designed to work with Sony's unique series of incredibly advanced speakers, amps, and subs that are optimized for high-res performance.

ESS DAC w/ High-Precision Clock Generator: Experience the same caliber of sound usually reserved for high-end home audio products, thanks to the ESS DAC chip (ES9018S); an industry-leading 32-bit D/A converter that provides optimum quality from all your digital music files. A high-precision clock generator works to improve digital-to-analog conversion accuracy. The clock generator further refines digital-to-analog conversion for precise, stable sound.
High Rigidity Chassis & Aluminum Front-Panel: The RSX-GS9 High-res digital media receiver has a high rigidity receiver chassis. This minimizes internal and external vibrations, achieving ultra-low distortion even in harsh in-car environments. Its machined aluminum front-panel offers a sophisticated design and minimizes unwanted resonance even further.
Separate Chassis Blocks: The dual-layer design of the chassis separates analog and digital circuitry, preventing noise and interference for uncompromised sound quality. Each component bock has its own dedicated circuit to optimize performance.
High-End Operation Amp & Audio Capacitors: High-end operation amp components (MUSE8920) are used in the RSX-GS9's analog circuits for greater depth of sound and audio realism. Sony's specialized audio capacitors work to deliver high-fidelity sound with a bright, full-bodied tone
6ch/5V Preamp Outputs: The Sony RSX-GS9 Hi-Res digital media receiver is equipped with 5-volt Front, Rear, & Sub pre-amp outputs giving you the ability to connect external amplifiers to your car stereo system. The unit's subwoofer preamp output is non-fading.
Note: This unit is not equipped with a built-in amplifier. You will need to purchase an external amplifier(s). The Sony XM-GS4 amplifier supports Hi-Res audio.
Optical Output: The head unit's Optical (Toslink) digital output is designed for connecting a power amplifier with an optical digital input. When the optical connection is made, the volume controls on the front panel or remote commander are bypassed. Other settings, such as Subwoofer, Pos Custom, Pos Preset, EQ10 Preset, Balance, Fader, and DSEE HX are automatically set to Off.
DSEE HX Upscaling: DSEE HX technology injects more life into your music, upscaling compressed files to near High-Resolution Audio quality. Restoring the subtleties of the original recording gets you closer to the sound of a live performance. This feature can only be accessed from the SongPal app on your Apple iOS or Android device.
High-Pass & Low-Pass Filters: The front & rear preamp outputs offer a selectable high-pass crossover frequency of 50Hz, 63Hz, 79Hz, 99Hz, 125Hz, 158Hz, 198Hz, 250Hz, or Off. You can also adjust the slope (-12, -24, -36, or -48 dB/oct) of the high-pass crossover. The subwoofer preamp output features a low pass filter with a selectable cut-off frequency of 50Hz, 63Hz, 79Hz, 99Hz, 125Hz, 158Hz, 198Hz, 250Hz, or Off. You can also adjust the slope (-12, -24, -36, or -48 dB/oct) of the low-pass crossover. These HP & LP filter settings can be controlled from the included IR remote or SongPal app.
Sub Control: You can adjust the subwoofer preamp output's volume level (-10 to +10dB) independently from the head unit's main volume control. In addition, you can select the phase of the subwoofer output from Normal or Reverse. Sub controls can be adjusted from the included IR remote or SongPal app.
EQ10: R&B, Rock, Pop, Dance, Hip-Hop, Electronic, Jazz, Soul, Country, Custom, or Off (Flat). The Custom mode allows you to make your own equalizer settings. You can adjust the level (+/-6dB) of 10 different frequency bands - Band1 (32Hz), Band2 (63Hz), Band3 (125Hz), Band4 (250Hz), Band5 (500Hz), Band6 (1khz), Band7 (2khz), Band8 (4kHz), Band9 (8kHz), and Band10 (16kHz). The equalizer curve setting can be memorized for each source. The EQ presets can be selected from the remote, while the custom EQ has to be configured from the SongPal app on your Apple iOS or Android device.
Listening Position: This unit can change the localization of sound by delaying the sound output from each speaker to suit your position, and simulate a natural sound field with the feeling of being in the center of it wherever you sit in the car. You can choose from Front Right, Front Left, Front, Center (All), or Off. You can also set the subwoofer distance of the subwoofer to Near, Normal, or Far. You can even manually set the distance from each speaker to your desired position from 0' to 11.5'. These time-alignment settings can be controlled from the included IR remote or SongPal app.
Loudness: The Loudness feature reinforces bass and treble for clear sound at low volume levels. Loudness is controlled from the included IR remote or SongPal app on your mobile device.
