NEW LEVEL STUDIO POWER
Expensive-sounding discrete mic preamps and vintage gear emulation
The Antelope Audio Discrete 4 console-grade discrete microphone preamp interface comes with four 6-transistor discrete
preamps, 121dB dynamic range conversion, and rock-solid clocking. Discrete 4 also features the Antelope Audio premier
real time FPGA FX modeling of iconic studio gear from BAE, Lang, Gyraf Audio, FET, and many more.
1. Safety Notes
To reduce the risk of electrical shocks, fire, and related hazards:
Do not remove screws, cover, or cabinet. There are no user serviceable parts inside. Refer servicing to qualified
service personnel.
Do not expose the device to rain, moisture or spillover of liquid of any kind. Should any form of liquid or a foreign
object enter the device, do not use it. Switch off the device and unplug it from the power source.
Do not use the device until the foreign object is removed or the liquid has completely dried and its residues fully
cleaned up. If in doubt, please consult with the manufacturer.
Do not handle the power cables with wet hands! Make sure the device is switched off when plugging and
unplugging it from the power source.
Avoid placing any objects on the cabinet or using the device in a narrow and poorly ventilated place. Doing so
could affect its operation or the operation of other closely located components. If anything goes wrong, turn off the
device first and unplug the power.
Do not attempt to repair the device yourself: consult authorized service personnel or your dealer.
Do not install the unit near any heat sources such as radiators, stoves, or other apparatus (including amplifiers) that
produce heat.
Do not use harsh chemicals to clean your Unit. Clean only with specialized cleaners for electronics equipment.
Connect all your devices before powering your Unit. This unit is connected via its power cord to the mains safety
earth. Never operate the unit without this earth connection.
Power supply cable should be routed so that it is not likely to be walked on or squeezed by items placed upon or
against it.
To completely turn off the device, unplug the power cable first from the outlet and then from the rear panel of the
unit.
Both, occasional and continued exposure to high sound pressure levels can cause permanent ear damage via
headphones and monitors.
The device is designed to operate in a temperate environment, with a correct Operating Temperature of: 0-50 °C, 32- 122
°F
2. Introduction
Thank you for purchasing Discrete 4 from Antelope Audio.
Discrete 4 was developed after an extensive research of legendary microphone preamp circuitry. While they sound great
on their own, the Antelope Audio FPGA engine is able to transform them into several classic units. It all happens in real
time and with as authentic responsiveness as possible!
Discrete 4 includes Accusonic 3D microphone and preamp models, guitar amp sims, transformer & tube FX, and a huge
selection of classic vintage gear
Although Discrete 4 was designed to work with any microphone, it really shines with the Antelope Audio Edge and Verge
modeling mics. They are designed to exclusively match the discrete preamp architecture of the interface, though they
perform very well with other products.
Furthermore, the Antelope Audio real time FPGA platform is now extended to a complete professional studio experience,
boasting a selection of classic Microphones, Preamps, Conversion, Compressors, EQs, Guitar Amps & Cabinets, and our
AuraVerb reverb. Use them within the Discrete 4 Control Panel, or in your favorite DAW.
Perform and record in real time with the FX, or apply them during production.
Like most Antelope products, Discrete 4 is a rock-solid clocking solution itself. It borrows our 4th Generation 64-bit
Acoustically Focused Clocking (AFC) technology you may know from Antelope classics like the Trinity & OCX HD master
clocks, or the Pure2 mastering converter. With two Word Clock outputs, the Discrete 4 is an exemplary master clock in
itself, letting you distribute its clock signal across your studio.
The Monitoring features in Discrete 4 are very flexible and a breeze to set up. Create up to 4 individual monitoring mixes
and send them to Headphones or Monitor Outputs, with or without FPGA FX. Our Vintage EQ, Compression, and
authentic Guitar Amp emulations let recording artists experience fully convincing sound that comes as close to the real
thing as possible.
With Discrete 4, users can save and load AFX presets and exchange settings with all Antelope Audio FPGA-equipped
interfaces. Sharing your own FX settings with other devices and users is quick and easy.
What’s more, the free-to-download Discrete 4 Remote App (Android & iOS) lets you adjust all microphone input levels and
grants full control over Monitoring, and Headphone volumes. For the first time, musicians can control their own
headphone volumes through their smartphones, too.
We hope you enjoy working with the Discrete 4 and take full advantage of all the possibilities it has to offer!

Enjoy working with Discrete 4!
All the best,
The Antelope Team
