    Console-grade and fully discrete preamps for best-in-class sound.
    Discrete 4 was developed after an extensive research of legendary microphone preamp circuitry. The Antelope Audio FPGA engine transforms its already expensive sounding Accusonic preamps into several classic units. It's all happening real-time and with as authentic responsiveness as possible.

    Enjoy the sound of legendary FX gear in your DAW
    The Antelope Audio real-time FPGA platform is now extended to a complete professional studio experience - Microphones, Preamps, Conversion, Compressors, EQs, and Reverb. Use them within the Discrete 4 EasyPanel or in your preferred DAW via the new AFX2DAW Plugin. Perform and record either with FX or process in post-production.

    Transform Edge & Verge into vintage replicas
    Inside the Discrete 4 FPGA Accusonic 3D modeling engine you can transform both Edge and Verge into vintage replicas giving you complete control over proximity effect, off-axis response and even allow you to change polar patterns during or after recording. Choose from a collection of classic and expensive microphones and track the results as you monitor live, bringing out a musician's best possible performance.

    Proprietary jitter management technologies
    Like all things Antelope Audio, Discrete 4 is a rock-solid clocking solution itself. It comes packed with the 4th Generation 64-bit Acoustically Focused Clocking (AFC) technology you already know from Antelope classics like Trinity, OCX HD and Pure2. Two Word Clock outputs allow you to distribute clock signal to your other digital gear.

    Maintain multiple mixes and exchange presets
    Monitoring and Talkback features in Discrete 4 are super flexible and a breeze to set up. Create up to 4 individual monitoring mixes. Send them to Headphones or Monitor Outputs with or without the FPGA FX you've stacked. Vintage EQ, Compression and authentic guitar amp emulations will allow the recording artists to experience convincing sound, which is as close to the final product as possible.

    With Discrete 4 users can save and load AFX presets and exchange settings with all Antelope Audio FPGA-equipped interfaces. Share your own FX settings with other devices and users.

    Control Discrete 4 with free desktop and mobile apps
    The free to download Discrete 4 remote App allows you to adjust all microphone input levels. It grants you full control over the Talkback levels, Monitoring and Headphone volumes. Musicians can now control their own headphone volume through their smartphones.

    Edge features dual edge-terminated capsules for a smooth/natural sound reproducing the expressiveness and character of expensive classic microphones. Antelope founder Igor Levin designed groundbreaking fully discrete electronics. Hand selected capsules encased in a carefully crafted enclosure with contours and shape for optimal sonic performance. Edge is an exquisite large diaphragm microphone with excellent transient response and capable of multiple polar patterns.
