USING THE ITRACK ONE PRE
Power considerations
The iTrack One Pre requires no batteries or separate power supply (but read on!).
When in use, it is powered from the iOS device to which is connected. Because the iTrack One Pre is
an active device, the battery in your iOS device will run down at a faster rate than it does in the device
alone, but this shouldn’t cause you any problems; it is simply good practice to make sure that there
is plenty of battery life in the device before you start recording.
The iTrack One Pre can also supply 48 V phantom power to a condenser (capacitor) microphone.
A condenser microphone consumes power itself, so remember that using one will further affect
the rate at which your battery runs down. Many modern condenser mics will work straightaway,
but some older or professional studio mics may require more current than the iTrack One Pre can
supply from your iOS device. You will know if this is the case because the 48V status LED will turn
from green to red. If this happens, you can power the iTrack One Pre from a standard household USB
power adaptor (e.g., an iPhone charger) using the USB cable supplied.
NOTE: Using an external USB PSU to power the iTrack One Pre does NOT charge the battery in your
iOS device.
To summarise:
• Your iTrack One Pre will normally be powered by your iPhone or iPad
• Use an external USB power supply only if:
• The 48V LED turns red when you connect a condenser mic, or
• Your iPhone or iPad has low battery life
