DC Power
Duet is easily powered by any available USB port on
your Mac in most applications. However there may be
scenarios where connecting the external AC power
adaptor is preferred or required.
There are two factors contributing to increased
power consumption:
•
Output volume into low impedance headphones
•
Phantom power for condenser mics.
This will appear on the OLED if the external
power is necessary with Mac
If you have Duet set at a reasonable volume, you are
not drawing a significant amount of power over the
USB bus and will be able to connect any microphones
that require phantom power. When you are using low
impedance headphones and your volume is very high,
you are drawing more power over the USB bus and
may need the AC adaptor to use power hungry
condenser mics.
When connected to iPad, iPod Touch, or iPhone, the
DC power supply for Duet MUST be used. Duet will
charge your iPad while you record so your work will
not be interrupted.
USB
Duet includes a single connection with two included
cables, providing connectivity to either a USB port on
your Mac or to a 30-pin connection on your iPad/iOS
device. Connection to iOS devices with Apple’s
Lightning connector requires Apple’s Lightning to 30-
pin adapter. Sold separately.
