Bringing All-Star Technology & Performance to a new audience
Antelope Audio’s Discrete 4 Microphone Preamp Interface brings a new level of sound quality and power to home studios and mobile recordists. It comes with 4 console-grade, 6-transistor discrete preamps, 121 db dynamic range conversion and rock-solid clocking. Discrete 4 features all of the Antelope Audio premier real-time FPGA FX, including authentic models of iconic gear from BAE, Lang, Gyraf Audio and many more.
The Antelope AFX platform is based on a rapidly expanding hardware modeling engine. Discrete 4 includes Accusonic microphone and preamp models, guitar amps, transformer and tube FX, and a huge selection of classic vintage gear, which are now accessible in the DAW via the new AFX2DAW Plugin.
Discrete 4 is a 14in/20out interface featuring 4 analog ins, 4 analog line outs, stereo monitor outs and 4 headphone outs. Digital connectivity comes on S/PDIF and ADAT.
An Entire Signal Path of Customizable Sonic Excellence
Discrete 4 was developed after an extensive research of legendary microphone preamp circuitry. Its console-grade and fully discrete preamps were hand designed to offer world-class sound. The powerful Antelope Audio FPGA engine can transform these already expensive sounding Accusonic preamps into classic units via Tube, Transformer and FET based circuitry. It's all happening real-time.
Both the engineer and the performer can instantly hear the authentic blends of 10 different mic preamps without any latency or annoying comb filtering. The microphone source can be recorded with and without Accusonic modeling. This allows the engineer to experiment with different preamp models during mixing. The entire signal path was designed for optimal sound with any microphone and it really shines with Antelope’s new Edge and Verge microphones. These new microphones were specially designed for the Discrete 4 preamps and feature matching discrete electronics.
The real-time FPGA platform offers a complete professional studio experience – Microphones, Preamps, Conversion, Compressors, EQs, Reverb and latency free Monitoring. All this backed up by Antelope's signature Clocking and combined into one unified system with instantly recallable Presets. You can even load AFX Presets from VIP Masters with their favorite combinations of FPGA FX that are used daily on their own award-winning mixes.
A Breakthrough Discrete Microphone Preamp Design
Traditionally, interface preamps are comprised of only 2 transistors, which makes them a hybrid between transistors and IC chips. Antelope Audio incorporates a fully discrete design consisting of 6 accurately matched transistors, yet maintaining the advantages of digital control and repeatability of gain levels. Field effect transistors add an expensive-sounding touch of warmth and naturalness to the sound. Bipolar transistors keep THD and noise extremely low, which is quite uncommon in a discrete design.
Antelope’s console grade 6-transistor discrete preamp is exceptional and unique. The Discrete 4 mic preamps were the first step of the device design process. Unlike other units where mic preamps are added to the interface, the Discrete 4 preamps are actually what the device is centered around.
Clocking Is The Center Of The Antelope Universe
For 25 years, Igor Levin has led the world in pro audio clocking technologies. His proprietary clocking techniques and secret jitter management algorithms have been at the core of the Antelope sound in all of their products.
The Discrete 4 is no exception. In fact, this mic preamp interface is a professional clocking solution in its own right. It features Antelope’s 4th Generation 64-bit Acoustically Focused Clocking (AFC) technology from the highly acclaimed Trinity, OCX HD, LiveClock, Pure2, Goliath, Orion, and Zen products. Two WC outputs allow you to distribute clock to your other digital gear. Discrete 4 will ensure all your gear is perfectly synced.
Expert Monitoring With Ease For Both Pros and Beginners
Discrete 4 has a comprehensive and easy to set up Monitoring and Talkback section. A band can have up to 4 individual monitoring mixes with FPGA FX included sent to its 4 Headphone Outs. The engineer can make custom headphone mixes for each performer. Effects can be included to allow artists to hear sound closer to what will be on the record.
Users can create custom presets to easily setup various tracking scenarios in a snap. The front panel features an assignable monitor volume knob to control level of the Stereo Outs and individual Headphone Outs. Metering is viewable on the front panel display, inside the Control Panel and also via the remote App.
A Rapidly Growing Audio Interface Platform
Discrete 4 can save and load AFX presets and exchange settings with the entire Antelope line of FPGA equipped pro audio interfaces. This means that you can share your own FX settings with other Antelope users and load professionally programmed stacks of FX from the Pros. This makes Discrete 4 a great option for both new users and existing Antelope owners, who use a second rig for touring or travel. This helps users leave their current studio untouched when on the road or doing session work outside their own facility.
Remote Control via IOS and Android Phones or Tablets
Use the Discrete 4 downloadable remote App to adjust all microphone input levels, Talkback levels, as well as Monitoring and Headphone volumes remotely. Musicians can control their own headphone volume with their phones and the engineer can check input levels from the tracking room.
