Apogee ONE | User’s Guide for Windows 
External Power 
Both versions of ONE are capable of being powered completely by the USB bus power provided by 
the computer’s USB port. However some Windows PC’s may not provide adequate bus power. In this 
case, connect the ONE’s DC power supply to guarantee proper performance. 
When connected to iPad, iPod Touch, or iPhone, external power is required. 
Here are the options for DC power: 
ONE for Mac (Silver) 
Connect ONE for Mac’s power supply (sold separately) to power ONE for Mac and charge the iOS 
device. 
ONE for iPad & Mac (Black) 
1. Connect ONE’s for iPad & Mac’s power supply (included) to power ONE for iPad & Mac and 
charge the iOS device 
OR 
2. Install two AA batteries (not included) in ONE’s battery compartment as shown. The iOS 
device runs from it’s internal battery while ONE runs from the AA batteries. This allows the 
entire system to be completely mobile. 
To install AA batteries, use a coin or screwdriver to remove ONE’s battery compartment door. 
Orient the 2 batteries as shown below so that the batteries’ minus (-) terminals are installed against 
the compartment’s springs. Once batteries are installed, replace the compartment door.
