External Power
When connecting to a Mac, both versions of ONE are
easily powered by any available USB port; there’s no
need to connect an external DC power supply.!
When connected to iPad, iPod Touch, or iPhone, external
power is required. Here are the options for DC power:!
ONE for Mac (Silver)!
1.
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.!
2.
Install two AA batteries (not included) in ONE for
iPad & Mac’s battery compartment as shown to the
right. The iOS device runs from its internal battery
while ONE for iPad & Mac runs from the AA
batteries. This allows the entire system to be
completely mobile. !
To install 2 AA batteries, use a coin or screwdriver to
remove ONE for iPad & Mac’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.
 !
When powering ONE for iPad & Mac from two AA
batteries, it is highly recommended to use NiMH
rechargeable batteries for the best battery life when
recording and playing back audio. Approximate battery
life is shown below for minimal and maximum load
conditions when using standard and rechargeable NiMH
batteries. !
About 5-10 minutes before ONE for iPad & Mac shuts down, the level meters’ red LEDs will flash to warn of the
approaching loss of power under most conditions. (see Note 1 below).!
After changing batteries, it is necessary to power cycle ONE for iPad & Mac by removing and then re-inserting the USB
connector.!
Note - & Max load condition is as follows: Input 1 set to Ext 48v Mic with a 10mA phantom power load, Input 2
accepts a 1kHz tone at -1 dBfs, output set to maximum. Unit is set to 96kHz sample rate. !
