X1 USB to SPDIF Converter

    X1 Converter

    Upgrade your USB DAC to Asynchronous 24/192

    USB inputs on many DACs don’t support resolution beyond 16-bit/48kHz. The Peachtree Audio X1 USB to SPDIF Converter interfaces between your computer’s USB output and your DAC’s SPDIF input (coax or optical) to provide a high-resolution upgrade over your DAC's stock USB input.

    The X1 lets you fully enjoy the highest-resolution digital music available – all the way to 24-bit/192kHz resolution!

    If your computer's operating system is Windows XP, Windows 7 or Windows 8 you'll need a small easy-to-install driver to unlock the X1's 24-bit/192kHz resolution. No driver is needed for Mac OS X. Download WIndows Driver Now.


    • If you need to run a long USB cable (over 3 meters) from your computer to your audio system you'll likely experience dropouts. Instead, use an X1 with a 1.5M USB cable from the computer and a 1.5M 75Ω SPDIF cable to the system. The connection should now be rock solid.

    • The X1’s USB input is transformer-coupled so it is effective at isolating noise from the computer and preventing it from getting to the DAC. The transformer-coupled X1 can also assist in solving ground loop issues.

    High Resolution

    The Peachtree Audio X1 lets you fully enjoy the highest-resolution digital music available – all the way to 24/192 – and includes native support for the popular 88.2 and 176.4 sampling rates. USB inputs on many DACs don’t support resolution beyond 16-bit/48kHz. The X1 USB to SPDIF converter interfaces your computer’s USB port with your DAC’s coax or optical SPDIF input and provides an easy upgrade for your USB DAC.

    Asynchronous USB

    Asynchronous communication keeps digital distortion – timing errors known as jitter – at bay by not relying on the audio clock in the computer. This internal clock can get thrown off time by the thousands of processes running in your operating system’s background. With asynchronous USB, the precision audio clock in the X1 takes control of the flow of data coming from the computer, resulting in significantly lower incoming jitter and superior sound quality. Asynchronous benefits all of your digital music files – from MP3 to 24/192 high-res. If you don’t have an ESS Sabre based DAC, we highly recommend using asynchronous USB.

    Bit-perfect feed into your DAC up to 24/192

    The X1 uses two crystals for accurate playback of the various sampling rates of your digital files with native support for 16-bit and 24-bit: 44.1, 48, 88.2, 96, 176.4, and 192 kHz. Many USB inputs on DACs rely on a single crystal with native support for one sampling rate multiple. Using one crystal per sampling rate “family” results in superior timing and clearer sound than single crystal solutions.

    Transformer coupled digital output

    Computers are prime sources of electrical noise. Electrical noise can be an audio intrusion that you can’t hear directly which can mask fine details and distort the tone of music. A pulse transformer on the coax output isolates electrical noise so only the pure digital bitstream is fed to your DAC for noticeably quieter backgrounds. The optical connection is inherently isolated from electrical noise. Whenever possible, we recommend using the coaxial digital output for the best sound and for its superior bandwidth when dealing with sampling rates above 96kHz.

    USB Class 2.0 Compliant

    The X1 is USB Class 2.0 compliant making it plug-and-play on the Mac OS X operating system.

    For Windows (Windows XP, Windows 7 and Windows 8) a small easy-to-install driver is needed to unlock 24/192. Download Windows Driver Now.

    USB Bus-Powered

    The X1 is powered by your computer’s USB port. No awkward wall wart power supply needed.
