Synergy Core Processing: Future-Proof Your DAW

Under the hood, the Discrete 4 Synergy Core is loaded with twin DSP chips plus an FPGA processor that work together to run Antelope Audio's vast collection of vintage-inspired effects plug-ins -- without sapping power from your host Mac or PC. Synergy Core increases your recording rig's stability by offloading audio effects processing to your Discrete interface's dedicated chips. Adding the Discrete 4 Synergy Core to your system means your DAW can make more efficient use of available CPU power -- extending the life cycle of your existing Mac or PC, so you don't have to upgrade to a latest-spec computer just to run all your favorite plug-ins. With Antelope effects running on Antelope hardware, your system is optimized right out of the box -- allowing you to shorten your audio buffer size, reduce latency, eliminate clicks and pops, and free up your host computer to run CPU-heavy VST synths, samplers, and native time-based effects.

1 FPGA + 2 DSP = More Effects, More Variety

Antelope Audio's industry-leading FPGA audio processing platform gives you lower latency in effects chains, allowing you to stack effects while adding mere microseconds, not milliseconds, to your signal. The Discrete 4 Synergy Core fuses both FPGA + DSP chips in one Antelope audio interface, harnessing the parallel processing power of FPGA alongside the latest-generation state-of-the-art ARM DSP chips developed for cloud computing and mobile tech -- processors that deliver a faster clock rate than other DSP chips used in the audio interface market. This exclusive hybrid architecture offers computing power synergies unique to Antelope Audio, greatly expanding the variety of Antelope effects that can be developed -- including time-based delays, choruses, flangers, and beyond. Your Discrete 4 Synergy Core arrives loaded with 36 Antelope FX included free -- classic compressors, studio EQs, must-have reverbs, tube guitar amp models based on iconic vintage gear -- and all the processing power you need to run them!

Uncompromising Analog-to-Digital and Digital-to-Analog Conversion Quality

A-to-D and D-to-A converters are at the heart of every DAW-based audio recording and playback system -- and your converters can make or break your studio. That's why the Antelope Audio Discrete 4 Synergy Core is loaded with proven, best-in-class AD/DA with 121 dB of dynamic range on the analog inputs and monitor outputs -- so you can capture and monitor your sound with Antelope clarity at up to 192 kHz/24-bit resolution.

Comprehensive I/O in a Portable Desktop Audio Interface

The Discrete 4 Synergy Core offers all the same I/O as Antelope's hit original Discrete 4 interface. With both USB and Thunderbolt I/O, the Discrete 4 Synergy Core lets you choose how you want to connect to your Mac or Windows PC. On the front panel, you'll find two XLR-1/4" combi inputs with switchable mic/line/instrument preamps, and four independent headphone outputs -- enough for you and all the artists you're recording. Take a look at the back panel, and you'll see two more XLR-1/4" combi inputs, two 1/4" outputs to feed your monitors plus 4 more line outs to connect to outboard gear, ADAT and S/PDIF digital I/O via optical TOSlink, and two Word Clock outputs to get your studio in sync with Antelope's legendary digital clocking. Hand-built by Antelope engineers to give you extensive analog and digital I/O in a robust, compact unit, the Discrete 4 Synergy Core gives you serious bang for your I/O buck.

Antelope Audio's Proven Clocking Technology

Top recording studios, film and broadcast facilities, and massive live productions rely on Antelope Audio master clocks like the OCX HD and Pure2 to maintain stability and sonic integrity in PCM digital audio. A reliable master clock lies at the heart of every pro studio, and the Discrete 4 Synergy Core wouldn't be an Antelope Audio interface if it didn't offer rock-solid clocking. Loaded with Antelope's 4th-Generation 64-bit Acoustically Focused Clocking (AFC) jitter management algorithm, the Discrete 4 Synergy Core offers two 75-ohm BNC Word Clock outputs so you can expand your studio with more digital gear and clock it all to the Discrete 4 Synergy Core. Add Antelope's industry-leading digital clocking to your studio, and capture recordings with greater clarity, dimension and detail.

"Very Happy With Product"
Overall: 10 out of 10 stars
Verified Customer zZounds has verified that this reviewer made a purchase from us.
I bought this unit to be a pre amp and mic combo for my current DAW setup. I am very happy with the various quick mic setups that come with the unit. I was unaware of the additional $50 dongle needed for setup - dongle not included - also needs to be ver 2 or better. Likewise, using Wind 10 OS, cannot have both say MOTU and Antelope being used at the same time as you can if using a Mac OS. Also important to note, that you can use the SPDIF link between two ADC/DACs (for example, I have the MOTU interface).. and to save an audio input to the MOTU from the antelope preamp analog input, I use the SPDIF clocked output to the MOTU input... THese are more setup/integration issues I came across... but main thing is the quality and the ease of getting a main vocals mic setup quickly and with variation when needed and the processing is not done on the PC. Support was very good.. used them 3 times and they returned my call the same day.
