Power
The Echo 2 may be powered either from a computer over the USB cable, or from the
included power adapter. The adapter plugs into the DC power jack on the right side as
shown below:
Phantom power (+48V) can require more power than your computer’s USB port can
deliver. Late-model Macintosh computers or PCs with USB 3.0 ports may provide more
power. Echo recommends using the external AC adapter whenever phantom power is
switched on.
USB power can be noisy, resulting in audible ground hum, or decreased audio
performance. If you are experiencing these problems, try using the external power
adapter.
USB
When used for digital audio recording and playback, the Echo 2 connects to a computer
using the USB mini-B jack on the rear of the case. The Echo 2 requires a cable that
has been certified for USB 2.0 high-speed operation.
