    Product Description

    Here’s What Antelope Audio Say About the Synergy Core Galaxy 64

    Unprecedented solution for the most demanding recording environments

    GALAXY 64 SYNERGY CORE is a high-end recording system that connects your entire studio within a 2U rack space while providing high-fidelity audio and onboard plugin processing for your most demanding projects. With Dante, HDX and Thunderbolt connectivity, the world’s first 64-channel AD/DA converter offers unbeatable flexibility when moving sound around your high-profile production facility, live stage, broadcast, or other enterprise applications.

    Simultaneous Use Of All Digital Ports

    Galaxy 64 Synergy Core is the only interface to offer two Dante® ports for audio networking, four HDX ports for a full array of 128 channels at 192kHz sample rate in Pro Tools as well as Thunderbolt™ connectivity. These features can be used simultaneously with multiple systems for easy adaptation to different workflows with preferred DAW applications. This is all made possible by utilizing our exclusive FPGA configuration and advanced digital routing.

    High-Fidelity Audio Performance

    High-spec AD/DA converters provide low total harmonic distortion and signal-to-noise ratio for artifact-free recording sessions. Signature clocking technology helps deliver accurate width, separation, and detail in musical performances.

    36 Real-Time Synergy Core Plugins Included

    The collection is largely composed of software emulations of vintage analog gear found in world-renowned facilities. The onboard Synergy Core offloads all processing to the interface while allowing direct monitoring with plugins in real-time with no perceived latency – a feature widely used in live performances.

    World’s First 64-Channel AD/DA Converter in 2U Rack Space

    GALAXY 64 SYNERGY CORE fits 64 channels of analog I/O in just 2U of rack space. The interface is designed to be the hub of your entire recording environment that eliminates the need for any external modules & expansion cards, thus centralizing your entire setup.

    Dante® audio over IP

    The audio networking choice of nearly all professional audio manufacturers, Dante® audio networking uses standard IP networks to transmit high-quality, uncompressed audio with near-zero latency.

    The ease of installation, affordable cabling and glitch-free transmission make Dante® the optimal choice for installations, live events, production facilities and any situation where large volumes of high-definition digital audio must be reliably transferred over large distances.

    Galaxy 64 Synergy Core joins the expansive Dante® ecosystem with dual RJ-45 ports, each carrying 64 channels of 24-bit/192kHz audio. This configuration provides straightforward integration and reliable redundancy, with the secondary RJ-45 port serving as a backup 64-channel Dante® route.


    Galaxy 64 Synergy Core is the only interface to offer four HDX ports. Each is a primary port, that enables interfacing to two HDX cards simultaneously for a primary/secondary recording setup or a full array of 128 channels ready to interface across multiple Pro Tools sessions through several hosts. What is especially impressive about our exclusive FPGA configuration is that it allows this channel count to be maintained at high sample rates such as 192kHz.


    Dual Thunderbolt™ 3 ports and custom drivers for Windows and macOS guarantee optimal cross-platform operation for the Galaxy 64 Synergy Core. Developed from the ground up and field-tested for low latency and stability at high sample rates, the Antelope Thunderbolt™ driver works behind the scenes to carry 64 channels of 192kHz audio wherever you want them to go – on both PC and Mac setups based around any market-leading DAW. The left Thunderbolt™ port enables USB-C connection to a secondary computer for remote control purposes. This is the first Antelope Audio interface featuring two Thunderbolt™ 3 ports that enable daisy-chaining.

    High-fidelity audio performance

    GALAXY 64 SYNERGY CORE employs high quality converters, providing low total harmonic distortion and signal-to-noise ratio. The dedicated monitor converter is of the same kind as those built into specialized mastering converters. This way, the Galaxy 64 Synergy Core does not require external converters for monitoring and facilitates critical listening without coloration or signal degradation.

    Internally, Antelope’s proprietary 64-bit Acoustically Focused Clocking & Jitter Management systems ensure the kind of audio quality that set apart the legendary Trinity OCX master clock - still employed in the most prestigious studios and production facilities.

    Synergy Core

    The Synergy Core real-time plugin processing platform employs 12 × ARM DSP and 2 × FPGA processors in a custom configuration, engineered to process tens of input/output audio streams and hundreds of low latency studio plugins in real-time.

    A single Galaxy 64 Synergy Core can handle large sessions with hundreds of plugin instances applied across 64 individual audio channels. Each channel strip can load up to 8 plugins at once in a “virtual rack” format, functioning as a standalone plugin processor per single channel. This allows for 64 “virtual racks” at once, with different plugin chains which operate simultaneously and enable multiple instances of your favorite signal processors.

    The interface includes a massive library of 36 real-time audio plugins powered by Antelope’s exclusive Synergy Core real-time plugin processing platform. Out of the box, this plugins library stretches beyond the essentials needed at any production stage, both studio and live, with 18 Equalizers, 12 Compressors & Limiters, 2 Preamps & Channel Strips, 1 AutoWah Pedal, 1 Tremolo, 1 De-Esser and 1 Reverb.
