Zen Quadro Synergy Core

Account Creation, Product Activation and Software Installation

Please note that the mandatory device activation procedure requires an active Internet connection on your computer. Activating an Antelope Audio device offline is not possible. Your Zen Quadro Synergy Core must be activated online to work. This article contains the necessary instructions: 


1. Connect the Zen Quadro Synergy Core primary USB 1 port to a Windows or macOS computer using a USB type-C cable. 


Important: Zen Quadro Synergy Core is a USB-C bus-powered interface and therefore it requires steady power from the computer ports. It is recommended to use ports such as USB 3, USB 3.1/USB-C that are located on the motherboard. Even though USB 2.0 ports may still be used, some may not deliver enough power. In such a case, the secondary USB-C port can be used.

F.A.Q.

How to adjust the sample rate when using secondary USB 2 port?

Typically, you cannot change the sample rate of your mobile device, so you need to manually match the sample rate of the Zen Quadro SC. If you are using a mobile device (connected to USB 2 port) together with a computer (connected to a USB 1 port), you need to adjust the computer sample rate to match the mobile device sample rate (change your DAW Audio settings or OS Audio settings). The numbers of the two sample rates have to always match:

 

If you are using only the USB 2 port with a mobile device, you need to navigate to the CONTROL MENU by holding the GAIN button, then go to Sample Rate and choose the correct sample rate, shown in red. Unplug the USB cable and plug it back in to reboot and sync the communication in case there is distortion. 

Can you connect the Zen Quadro SC to a Thunderbolt port?

Yes – you can connect it to a Thunderbolt 3 or 4 port because they are USB-C compatible. The Quadro will still work as a USB device. Thunderbolt 2 ports are not compatible.

Is afx2daw available for Zen Quadro Synergy Core?

No - afx2daw is not available for Zen Quadro. To use your real-time FX in the DAW, please refer to this article, showing how to set them up as hardware inserts.

Can the dual USB be used for redundancy in live setups?

Yes - the playback and recording on the two USB ports are independent from one another, so if one computer stops recording, the other one will continue to record. It’s important that both systems use the sample sample rate.

Interrupting the power delivery to the primary USB 1 port may result in the Zen Quadro SC to reboot, which will interrupt the playback/recording process. 

Can I connect and use the OTG functionality with an iPhone / iPad with Lightning port? 

Yes - to connect to an iPhone with Lightning port, you need a Camera Kit adapter (not included), because the Lightning port does not support connections in which the Apple device acts as a host (OTG). Since most Apple products with Lightning ports cannot deliver enough power, the Primary USB 1 port must be connected to a USB port or an external power supply, providing at least 5V and at least 1.5A. while the Secondary USB 2 port is connected to the Apple device via the Camera kit adapter:



Can I connect and use the OTG functionality on an iPhone 15 / iPad with USB-C port?

Yes - with a USB-C to USB-C cable (included). iPhone 15 can provide enough power to run the Zen Quadro SC on itself, but in case of insufficient power delivery from the iPhone/iPad, you can connect the primary USB 1 port to to a USB port or an external power supply, providing at least 5V and at least 1.5A.

Can Synergy Core real-time FX be used in the DAW as plugins?

You can use Synergy Core real-time FX as hardware inserts in any DAW, in the same way you would route an external hardware outboard as an insert. Please check out this article for further instructions.

My Zen Quadro SC does not turn on, what should I do?

⦁    If you are using with a mobile device only

In case you are trying to use a mobile device only, first make sure you have connected it to the secondary USB 2 port. 

If the Zen Quadro SC still does not boot up or keeps restarting, connect the primary USB 1 port to a separate power supply adapter or to a computer USB port, delivering 5V and at least 1.5A. 

⦁    If you are using with a computer

Zen Quadro Synergy Core is a USB-C bus-powered interface and therefore it requires steady power from the computer ports. It is recommended to use cables no longer than 1.5m (shorter is better) and computer ports such as USB 3, USB 3.1/USB-C that are located on the motherboard, delivering 5V and at least 1.5A. Even though USB 2.0 ports may still be used, some may not deliver enough power. In such a case, the secondary USB 2 port can be used for additional power supply, connecting it to another USB port or a separate power supply adapter.
