The Antelope Audio Discrete 4 Pro Synergy Core is a 14x20 Thunderbolt 3 and USB 2.0 audio interface with top-quality sound that offers a variety of connectivity options. Antelopes state-of-the-art hardware also includeds 37 analog-modeled real-time effects, which are powered by the onboard DSP and FPGA chips to ensure ultralow latency and no burden on your computer's CPU.
 
Each of the four Antelope Discrete mic preamps has its own phantom power and up to 65 dB of gain, so the interface is primed and ready for recording all sorts of microphones, instruments, or even line-level signals from outboard gear. Equipped with four independently adjustable headphone outputs, balanced monitor outs, and four DC-coupled line outputs, the Discrete 4 Pro Synergy Core can act as your studio's hub for multiple sets of headphones, mixes, monitor feeds, and more. Its ADAT and S/PDIF digital I/O ports are perfect for expanding your setup with digital gear such as external converters, and the wordclock outputs ensure professional synchronization with other interfaces and clocks.
 
Pro Model Updates
Compared to the Discrete 4 Synergy Core, the Discrete 4 Pro Synergy Core delivers improved performance with greater dynamic range, less total harmonic distortion and noise, and quadruple the available channel strips for effects processing. Also, it replaces Thunderbolt 2 connectivity with Thunderbolt 3 (in addition to USB 2.0) and offers adaptive on-screen metering plus extended routing capabilities.
 
Conversion and Clocking
The Discrete 4 Pro has been upgraded with studio-ready 192 kHz converters (up to 130 dB of headroom) and Antelope Audio's proprietary 64-bit AFC clocking. With the interface in your rack, you can experience a new level of detail in your recordings, and enjoy a wider soundstage for an exceptional stereo image in audio playback.
 
Preamps
Designed using a combination of transistors, the Discrete 6-transistor preamps result in high gain (up to 65 dB), minimal noise, and precise sound capture for pristine, transparent recordings.
 
Connectivity
The Discrete 4 Pro Synergy Core offers impressive analog and digital I/O in a compact, half-rack enclosure. Four mic/line inputs, two instrument inputs, four DC-coupled line outputs, a pair of monitor outputs, four headphone outputs, plus 8-channel ADAT and stereo S/PDIF I/O are at your disposal. For your computer connection, you have USB 2.0 and Thunderbolt 3 ports. All I/O is available at any time and can be used simultaneously without the need to change setups, making it easy to work on multiple sessions.
 
Hi-Z
Plug in your guitar directly to one of the two Hi-Z enabled inputs, and instantly sculpt your tone with guitar amps and cabinet models. Add compression, EQ, and AuraVerb while playing through your preferred amp, cabinet, and microphone combination.
 
Word Clock
Two wordclock outputs let you distribute the interface's highly stable clock signal across your studio.
 
Control Panel
A virtual routing patch bay on the Discrete 4 Pro Synergy Core streamlines the routing process and even adds creative possibilities. Apart from the intuitive routing, the software control panel allows you to create presets, quickly configure mixes with four fully independent 32-channel virtual mixers, and more. 
 
The FX 
The 37 effects included with Discrete 4 Pro are modeled after iconic studio equipment and can be applied in real time during monitoring, postproduction, and live recording. Aside from the exclusive compressors, EQs, and preamps, the interface comes with 22 guitar amps and cabs, a guitar tuner, and a signature reverb that are processed with near-zero latency entirely inside the interface, putting zero load on your host CPU.
 
Session Recall
For every individual recording scenario, you can save session files and create exact snapshots of your effect chains, so you can load them later without losing your progress.
 
Mic Modeling
The interface's Modeling Engine is ready to be paired with the Edge line of microphones for real-time use of vintage microphone emulations.
 
37 Real-Time Effects
The collection of 37 Synergy Core effects is powered by the Synergy Core proprietary onboard platform, which uses two DSP chips and one FPGA chip for real-time effects processing with imperceptible latency.
