How to input from Apple iDevice to USB DAC input?

post #1 of 3
Thread Starter 
Does the Apple Lightening-To-USB camera connector enable me to hook the USB input of a portable DAC to the digital output of my Apple iPod?

I know that there are some devices, e.g., Sony PHA-1, Centrance HiFi M8, Fostex HP-!, and others, that give you a special jack and internal software to do this.

But for the majority of DAC/amps that do not have this stated capability, will any adapter cord such as the Apple camera connector mentioned above enable this direct transfer of bits out of Apple device into the DAC?

Thanks!

It depends on the DAC or DAC-HPamp. If it needs special drivers (usually for high res and DSD) or runs completely off the USB power, then it might not work since the mobile devices can't supply a lot of current.

 

As for the iDevice, iPhone5 and iPad2 and newer all running iOS7 or newer should work otherwise - it anything some iOS5.x and iOS6.x updates lowered the output limit on the USB power when used as a host device, but they got rid of it in iOS7.

 

Here's an iPad2 on an Apple dock with the CCK on the sync port, working with the USB input of a Meier Cantate.2
