2. Introduction

Thank you for purchasing Discrete 8 from Antelope Audio.
Discrete 8 was developed after an extensive research of legendary microphone preamp circuitry. The Antelope Audio FPGA engine can transform its already expensive sounding Accusonic preamps into a plethora of classic units real-time. The microphone source can be recorded with and without Accusonic modeling. This allows the engineer to choose between preamp models during mixing.
Plug а guitar into one of the Hi-Z enabled inputs and sculpt your tone with the most iconic guitar amps and cabinets. Add vintage compression, EQ and AuraVerb to hear a finished studio quality result with real-time responsiveness. Perform and record either with FX or process later using the integrated guitar effects. The Discrete 8 ReAmp outputs will allow you to use any outboard gear and record the sound back in your DAW of choice.
Discrete 8 is designed as a professional clocking solution in its own right. It features Antelope’s 4th Generation 64-bit Acoustically Focused Clocking (AFC) technology from highly acclaimed clock units like Trinity, OCX HD, LiveClock and Pure2. Discrete 8 comes with a Word Clock (WC) Input that can de-jitter and distribute an external clock signal. Two WC outputs allow you to distribute clock to your other digital gear and mic preamps in your setup connected via ADAT and S/PDIF. Discrete 8 will make sure all your gear is perfectly sync”d.
The Monitoring and Talkback sections in Discrete 8 are easy to set. Up to 3 individual monitoring mixes can be sent to Headphones or Monitor Outputs, with or without FPGA FX. Custom headphone mixes might be tailored for each performer. Vintage EQ, Compression and guitar amps allow the artists to hear a sound as close to the final product as possible.
Discrete 8 can save and load AFX presets and exchange settings with the entire Antelope line of FPGA equipped pro audio interfaces. Share your own FX settings with other Antelope users or see how the pros are setting up their sessions.
The Discrete 8 downloadable remote App allows you to adjust all microphone input levels, Talkback levels, as well as Monitoring and Headphone volumes. Musicians can now control their own headphone volume through their phones. The engineer can check input levels from the tracking room. The device can be accessed from different computers connected to the same network.

6.2.11. DAW

 This section is dedicated to the Discrete 8 analog outputs – Line Out 1 & 2 and ReAmp (Line Out 3 & 4). Simply use the drop-down menu to choose which channel you want routed to which output. Use the Gain knobs to adjust output volume. Feel free to link the Line Outs for convenience.

6.3 AFX Rack

The AFX Rack is where you insert effects into a mixer channel, forming a Channel Strip to process audio with. It’s accessible by clicking inside the empty fields below the mixer’s BP buttons (in 8-channel view) or clicking the FX button (in 32-channel view).

The Antelope Audio AFX collection is vast, comprising an Equalizer, Compressor, the PowerGate noise gate, the AuraVerb reverb, 21 Vintage EQs, 13 Vintage Compressors, 10 Guitar Amps and 10 Guitar Cabinets. Additionally, our Mic Emulations currently number 11 models for the Edge large-diaphragm modeling mic, and 5 models for the Verge small-diaphragm modeling mic. We aren’t stopping here, our team is working hard to expand the AFX and Mic Emulations suites with more models of coveted studio gear!

We are confident you will find our emulations sound and behave incredibly lifelike. That’s because they are all happening in real time on the Discrete 8’s FPGA (field-programmable gate array) chip. FPGA technology lets us provide authentic, circuit-level emulations of classic studio hardware. Rather than “describe” circuitry in abstract DSP code, we dynamically re-configure the chip to behave exactly like it.

That’s right – we recreate all this rare vintage equipment on an actual hardware circuit, piece by piece. This way, the FPGA literally takes on the personality of the same circuitry and components that forged the sounds of countless classic records. It’s a bit of a marvel, really!

There are some limitations in place, however. The number of effects you can apply simultaneously depends on which Discrete 8 bundle you purchased. Here’s the breakdown:

  • Discrete 8 Basic – 2 channel strips with 4 FX instances each & all 50+ Antelope Audio real time FPGA FX emulations + Mic Emulations.
  • Discrete 8 Premium – 8 channel strips with 4 FX instances each & up to 16 channel strips using the upcoming AFX2DAW plug-in and all 50+ Antelope Audio real time FPGA FX emulations + Mic Emulations.

With this out of the way, let’s jump into the AFX Rack!

6.5 Routing System

With the EasyPanel Control Panel, we managed to greatly simplify our routing system without sacrificing any of its flexibility. When you become acquainted with with the Discrete 8 inputs and outputs, routing is simply a matter of navigating through a few drop-down menus!

6.5.1 Discrete 8 Inputs and Outputs

In the routing system, the inputs and outputs of the Discrete 8 are organized as follows:

  • General
  • Digital Outs
  • Analog Outs
  • DAW


These are the 8 Discrete Mic Preamps.


This is the signal affected by mic emulation.


These are your DAW outputs, up to 16 channels.


These are the 8 ADAT digital inputs.



These are the two S/PDIF digital inputs.


Enjoy the silence.

Oscillator O1 & O2

The two oscillators in your Discrete 8 can be routed to the interface’s outputs for testing purposes.

6.5.2 Example Routings

We believe learning by doing is the best approach to understanding our routing system. Hence, we came up with example routings to illustrate how several common recording scenarios will look inside the routing panel.
Considering the system's flexibility and the abundance of connectivity on the Discrete 8 — not to mention those great-sounding preamps and rock-solid clocking — we are confident our product can handle any recording task from the comfort of your desk. Let's begin!

Having troubles hearing any playback from Discrete 8?

⦁ Go to the Monitors & Headphones tab.

⦁ Head to the Monitor 1/2 or HP 1/2 section.

⦁ Route Computer Play channels 1 and 2 to a pair of mixer channels of your choice.

⦁ Pan the channels Left and Right accordingly, adjust the volume level with the fader, and consider linking them for your convenience.

⦁ You should be able to hear playback from your main monitors or headphones. If not, adjust the main HP or Monitor volume. 

Recording a microphone.

⦁  Connect the microphone to one of the preamps using an XLR connection.

⦁  If you are using a condenser mic, make sure you have rurned on the Phantom power (48V) from the software control panel. 

⦁  Adjust the gain of the preamps to get the proper signal level

⦁  Select the preamp you want to record into the DAW section on some of the channel strips in order to be able to record the signal inside your DAW

⦁  If you want to monitor the signal from the preamp, select the preamp you want to monitor into the Monitor/HP sections and adjust the volume and panning.

⦁  If you are recording a dual capsule microphone (for example Edge Duo), you need to use 2 preamps, which you can link, in order to have e

Recording an electric guitar.

⦁  Connect the guitar to one of the preamps  on the front panel using an TRS/TS connection.

⦁  Make sure you have selected Hi-z from the software control panel

⦁  Adjust the gain of the preamps to get the proper signal level

⦁  Select the preamp you want to record(preamp 1 or preamp 2) into the DAW section on some of the channel strips in order to be able to record the signal inside your DAW

⦁  If you want to monitor the signal from the preamp, select the preamp you want to monitor into the Monitor/HP sections and adjust the volume and panning.

⦁  You can add effects on the Monitor/HP or DAW section in order to monitor and record the guitar signal with our FPGA effects.

7. Advanced User Tips

Ground Loop Hum and Noise
The design of Discrete 8 minimizes the possibility of ground loop hum and noise. However, we recommend the use of shorter, shielded cables and balanced connections for all the audio signals of your system. All power cables of the system should be connected to a dedicated outlet box or power conditioner unit to avoid ground current noise affecting the audio signal path. It is also advisable to keep the layout of your signal and power cables separate.

ReAmp Outputs
The Discrete 8 ReAmp outputs are designed to be used with external effects whose outputs you would have to connect back into any inputs of the interface. Think of the ReAmps as separate outputs that you can use for external processing. They emulate the signal levels of an electric guitar in order to match the input of a guitar amp perfectly – hence the name ReAmp outputs. You can, however, adjust the output level yourself so you can control how “hot” you are going into an effect.

8. Troubleshooting

Start up and Sound Issues

Are you running the latest control panel and driver?
If not, please update your control panel and firmware.

Are you correctly routing the audio signal via the routing panel?
To hear playback, route the Computer Play channels to the Discrete 8 main outputs.

Have you set the correct sample rates?
On a Mac, first check that the sample rate is correct in the Audio & Midi set-up panel. Proceed to check in the DAW and finally, check the Discrete 8 sample rate. Everything should match.
For Windows, go to Playback Devices, right-click on Discrete 8, then click Properties. Move to the Advanced tab and select the correct sample rate. Proceed to check in the DAW and finally, check the Discrete 8 sample rate. Everything should match.

If you believe there is no sound being routed to an input or delivered from an output:

⦁ Check your source. Is there a signal being transmitted from the source? Is your source in the correct sample rate for the Discrete 8 to receive?
⦁ Check what clocking mode you are in.
⦁ Are you receiving clock signal from the source?
⦁ Check that the relevant lock light on the control panel of the Discrete 8 is lit.
⦁ Try a different cable and another source if available.
⦁ Check the routing on the control panel. Have you routed the signal path correctly?
⦁ If you have routed signals to the routing mixer, check their corresponding fader is up.
⦁ Check the relevant peak meters of the control panel by selecting them in the drop down menu to see if the relevant signal is being received or is being outputted.


What buffer size is your DAW set to?
⦁ If it’s significantly low, i.e. lower than 128 samples, try increasing it from the Discrete 8 control panel (Windows-only).
⦁ Is the input and output routing correct in your DAW? Is the Discrete 8 device selected in the relevant sound card section of your DAW’s preferences?
⦁ If the Discrete 8 doesn’t show up in your DAW, try unplugging and plugging back the USB 2.0 cable. Then, try restarting your computer. Finally, try re-installing the firmware, drivers and control panel.
