How to connect Zen Go to an iOS device
The Zen Go Synergy Core is class-compliant with modern mobile devices and connects to them for use with playback and recording apps. However, mobile devices do not supply USB bus power. The interface needs to be powered from an external USB power source, such as adapter, power bank, or powered USB hub and the device needs to be connected through an OTG Adapter for the connection to be successful.
Here's how to do this:
1. Connect the Zen Go Synergy Core to your mobile device using the USB-C port marked 'AUSB'.
2. Connect the USB power source to the Power USB-C port on the interface. 
3. Press and hold the 'HP/MON' button on the interface's top panel to enter the System Menu.
4. Turn the rotary control to select the 'Power Source' menu entry. Press the rotary control to enter.
5. Turn the rotary control to select the 'Power B' option. Press the rotary control to confirm.
6. Press the 'Antelope' button on the interface's top panel to exit the menu.
Note: Make sure the USB power source outputs at least 1A of electric current.

1. Connect the Zen Go Synergy Core to your mobile device using the USB-C port marked 'AUSB'.
2. Connect the USB power source to the Power USB-C port on the interface.
3. Press and hold the 'HP/MON' button on the interface's top panel to enter the System Menu.
4. Turn the rotary control to select the 'Power Source' menu entry. Press the rotary control to enter.
5. Turn the rotary control to select the ' Charge device A from B’ option. Press the rotary control to confirm.
6. Press the 'Antelope' button on the interface's top panel to exit the menu.

In both scenarios the device clock source needs to be set to USBCC
1. Press and hold 'Gain' to enter the Control Menu.
2. Turn the rotary control to navigate to Clock Source
3. Choose the clock source - USBCC
Note: *USB Class Compliant – when set on this clock source the device will work with
Android/Linux-based systems without drivers.
Note: Due to the vast amount of 3rd party products and specifications on the market, Antelope Audio cannot guarantee compatibility with Android and iOS devices. Zen Go Synergy Core does not come with any dedicated software for iOS or Android, and it can work only as a class-compliant device for playback and recording. Make sure the USB power source outputs at least 1A of electric current.
