Your iD interface LED ring will continually flash if the interface is not receiving enough power.
The iD4+ requires a 5V/3A (15W) power supply to operate. This elevated power requirement is necessary to drive the high-performance AD/DA converters, HMX circuitry, and headphone amplifiers.
Bus Power Requirements
To bus-power the iD4+, you must use a standard USB-C to USB-C cable connected directly to a host computer’s USB-C port capable of delivering 3A. For optimal performance, a direct connection to the host is highly recommended.
Using a USB Hub & External Power
If you are connecting the iD4+ via a USB hub, you must use an external power source. Please note the following external power requirements:
- Cable Type: The power source must deliver 5V/3A via a USB-C to USB-C connection. A USB-A to USB-C cable cannot be used for external power delivery, regardless of the power supply's amperage rating.
- Automatic Switching: When an external supply is connected, the device automatically bypasses bus power and seamlessly switches to the external source.
- Data Transfer: Once the unit is powered externally, you may safely use a USB-A to USB-C cable for data transfer via the main USB port on the rear panel.
When using external power please check the USB socket to ensure it is delivering 3A.
