Hi willhindson,
you're reffering to this adapter, right?
https://www.amazon.com/Apple-MK0W2AM-Lightning-Camera-Adapter/dp/B01F7KJDIMdon't have such device at the office , i only have the standard lightning camera connection kit.
I assume you're using the AudioFuse in full power mode(PSU + USB connection). Then i would kike to know that if you change AudioFuse power mode (green , mixdown, mixdown green), does it save the Ipad power in a better way?
as a reminder :
On green mode, you'll have access to all AudioFuse features, but max level for I/O will be +18dB (instead of +24dB when in full power)
On mixdown, you'll have access to outputs only, with max level of +24dB (and +18dB in mixdown green)
you can set the power mode in AudioFuse control center settings . "Auto" will equal to full power mode when connected with PSU+USB, or will equal to green mode if connected with USB only.
if you don't wan't to use AudioFuse control center , we've got a special trick for this!
while powering up the unit hold some buttons this way :
auto : hold phone 1 "mono" button while powering
green : hold phone 1 "cue" while powering
mixdown : hold "talkback" while powering
mixdown green : hold phone 2 while powering.
Hope this helps
best regards,
