Antelope Audio Discrete 4 Synergy Core - Under the Hood

Synergy Core Processing with DSP + FPGA processing

Under the hood, the Discrete 4 Synergy Core is loaded with twin DSP chips plus an FPGA processor that work in tandem to run Antelope Audio's vast collection of vintage-inspired effects plug-ins - with no hit to 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, thus extending the lifecycle of your existing Mac or PC. With Synergy Core, you don't have to upgrade to a latest-spec computer just to run all your preferred 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. These processors 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, such as time-based delays, choruses, flangers, and beyond. Your Discrete 4 Synergy Core arrives loaded with 36 Antelope FX included free. You get 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!

Synergy Core benefits:

  • Offload FX processing to reduce buffer size, record with sub-millisecond latency & monitor in real-time.
  • FPGA dynamically recreates studio effects & mic models on the circuit and component level.
  • Industry-standard DSP brings a wider variety of effects to an efficient real-time, low-latency platform.
  • Improves your computer's stability when handling CPU-heavy synths, samplers and FX.
  • Future-proof and configurable architecture lets us design each product for optimal performance.
  • FPGA eliminates the issue of latency stacking which is common with DSP-only units.

Four console-grade, fully discrete preamps

In the world of pro-audio design, there are certain recording consoles that stand apart from the rest based on their preamps alone. Rather than designing textbook generic preamps as are found in most audio interfaces, Antelope engineers took their inspiration from the circuitry of microphone preamps that have stood the test of time. However, the Discrete 4's preamps had to do more than stand on their own, they also “get out of the way” for the FPGA preamp models to shine through without any additional hype altering the performance of the models. After extensive research into both classic and modern preamp design, Antelope developed the Accusonic preamp; a Class-A, 6-transistor discrete preamp born of the great console designs. Not only do the Discrete 4's preamps sound stellar on their own, they can take on the sonic characteristics of a variety of classic preamps via the Antelope Audio FPGA engine - plus, it happens in real-time and with as authentic a response as possible.

Why use discrete transistor circuitry?

As we mentioned, the Discrete 4's preamps have to “get out of the way” for the FPGA models to work to their maximum capability. In order to achieve that, the best possible noise and distortion performance is essential. Discrete bi-polar transistors can outperform IC op-amps, (integrated circuit chips), particularly with low source resistances. The open-loop gain (for linearity) and load-driving capability provided by op-amps may have less than respectable performance specs, which ties into the second requirement of low distortion. Most op-amps have Class-B or Class–AB output stages, many of which show crossover artifacts on the distortion residual. A discrete op-amp (transistor) can dissipate more power than an IC, and thus can have a Class-A output stage, avoiding the crossover issue completely.

In essence, discrete transistor circuitry offers the lowest noise and distortion specs possible, enabling the FPGA FX preamp models to shine through without any uncharacteristic noise and distortion, which are also modeled to provide the true performance of the modeled preamp. Additional noise and distortion would turn the model into a different preamp, and not necessarily a better one. (Too much information? We at Pro Audio Design think not.)  

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.

Expandable FX Library

Tame peaks, give punch and add color to your tracks with an arsenal of vintage and modern compressors. Each one is a faithful reincarnation of a fabled unit that's been serving studios around the globe for decades - with the exception of Antelope's own Feed-Forward compressors, which we believe you will find quite powerful, yet transparent.
