Experiencing distortion issues when trying to use multi-channel input into iPad.

We have discovered the potential for audio distortion when iConnectAUDIO4+ has more than 2 channels enabled for output from the USB Device Jack that an iOS device is connected to. By default, iConnectAUDIO4+ has 6 channels enabled per USB Device Jack.

We have determined that this is not an issue with the iConnectAUDIO4+ hardware or firmware but rather software elements within the iOS device. We are working towards identifying the issue to the other parties and towards a mutual solution.

In the meantime, under iConfig’s Audio Info section for the USB Device Jack which connected to the iOS device, we recommend lowering the USB Device Jack Output Channels to a maximum of 2 and saved to device memory. This setting is how many channels are made available to the iOS device through the USB Device Jack.
