Put Antelope Audio's pristine AD/DA conversion and massive effects processing
power on your desktop with the Discrete 4 Synergy Core audio interface. A hot-
rodded upgrade to Antelope's popular Discrete 4 audio interface, the Discrete
4 Synergy Core gives you dual DSP chips plus an FPGA processor working in
harmony to run Antelope's expansive library of effects, as well as 3rd-party
effects joining the Synergy Core platform. The Antelope Audio Discrete 4
Synergy Core interface offers 4 console-grade discrete mic preamps, 14 total
inputs and 16 outputs, renowned Antelope digital clocking, and both
Thunderbolt and USB connectivity for your Mac or PC. Best of all, the Discrete
4 Synergy Core comes with $3,000+ of Antelope's top effects plug-ins included
free, so you can record, monitor, mix, and master your projects with world-
class sound from start to finish.

With a price-to-performance ratio that goes toe-to-toe with any Thunderbolt or
USB audio interface available, the Antelope Audio Discrete 4 is ideal for
musicians, artists and producers who need a compact, road-ready recording
setup that unlocks unprecedented power to create.

Synergy Core Processing: Future-Proof Your DAW with DSP + FPGA processing

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.
