Sound Pure's Take

The Antelope Audio Galaxy 64 Synergy Core represents the pinnacle of high-density conversion and studio routing. Designed for high-end recording facilities, scoring stages, broadcast environments, and large hybrid mix rooms, this 2U powerstation achieves what previously required racks of separate equipment: 64 channels of pristine analog I/O alongside multi-protocol digital connectivity across Dante, HDX, and Thunderbolt 3.

Beyond its massive channel count, the Galaxy 64 serves as an active processing hub. Equipped with Antelope's Synergy Core engine—which combines 12 ARM DSP cores and 6 FPGA chips—it offloads massive signal processing tasks from your host computer, running real-time low-latency vintage FX modeling across dozens of channels simultaneously. Driven by sub-millisecond conversion and Antelope's reference-grade 64-bit Acoustically Focused Clocking (AFC), it sets the benchmark for enterprise-level audio interfaces.

From Antelope Audio

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. 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.

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 options can be used simultaneously with multiple systems for easy adaptation to different workflows with preferred DAW applications. This is all made possible by utilizing Antelope’s exclusive FPGA configuration and advanced digital routing.

The interface comes with 36 real-time plugins in a collection largely composed of software emulations of vintage analog gear found in the world’s most 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.

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 two 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.

 

128 CHANNELS IN PRO TOOLS

Galaxy 64 Synergy Core is the only interface to offer four HDX ports. Each a primary port, they enable 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 Antelope Audio’s exclusive FPGA configuration is that it allows this channel count to be maintained at high sample rates such as 192kHz.

 

CROSS-PLATFORM INTERFACE

Two 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 Panel configurations. 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 numbers are at 124dB of dynamic range on the AD stage, 128dB at the DA stage and a dedicated monitor converter with 130db - the highest dynamic range in the system and in devices of this kind. The monitor converter is of the same kind as the ones 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 Isochrone Trinity master clock - still employed in the most prestigious studios and production facilities.

 

SYNERGY CORE REAL-TIME PLUGIN PROCESSING PLATFORM

The Synergy Core real-time plugin processing platform employs 12x ARM DSP and 2x FPGA processors in a custom configuration, engineered to process tens of input/output audio streams and hundreds of low latency plugins in real-time with imperceptible latency while placing zero load on your computer’s CPU. 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. There is no other singular platform that lets you place this many instances of legendary equalizers, compressors, Auto-Tune™ and other studio processors across this many audio channels. Galaxy 64 Synergy Core contains the audio and plugins processing power of a complex multi-rack setup at the potential cost of hundreds of thousands of dollars in purchase, installation, maintenance and support bills.

 

36 SYNERGY CORE PLUGINS INCLUDED

The interface includes a massive library of 36 real-time plugin emulations of vintage analog gear found in world-renowned studios. Find not only the most reputed units of the industry, but also some of the rarer pieces of hardware that are difficult to find. Out of the box, this plugins library stretches beyond the essentials needed at any production stage, both studio and live. Need more plugins?
