Echo 2 Connections
Audio connections are made using the four jacks on the rear of the Echo 2:
Inputs
The Echo 2 has two ¼” TRS (Tip-Ring-Shield) balanced input jacks labeled
“IN1” and “IN2”. You can connect virtually any type of analog signal to
these jacks, such as guitars, keyboards, microphones, line level signals, or
mixer boards. Each input has a built-in acoustically transparent, quiet,
studio-grade preamp.
You can plug a microphone directly into the Echo 2 without using an
external preamp. The Echo 2 can provide phantom power. If your
microphone has an XLR connector, you can use the included adapter
cable.
You can also connect guitars, keyboards, or other equipment using
¼”cables. Whenever possible, use balanced, shielded cables to limit
external interference. Unbalanced signals such as those from RCA
connectors and guitars should be connected using cables with mono plugs.
Once you have connected the inputs, set the appropriate mode for the
input using the touch panel. This will set up the internal preamp to match
the incoming signal.
If you prefer to use an external preamp, simply connect the preamp directly
to the Echo 2’s input, and set it for line level with unity gain. This will
preserve any unique sonic coloration or nuance.

Main Outputs
There are two output jacks labeled “OUT L” and “OUT R”. These are
standard low impedance, balanced outputs that can be connected directly
to a mixer board or powered speaker.
Headphone Output
A high quality stereo headphone output is provided by the front jack:
You can set the headphone volume using the touch panel.
For more information on operating the touch panel, please refer to that section of this
user guide.

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.

Touch Panel
The touch panel gives easy access to virtually all of Echo 2’s functionality. The panel
uses capacitive touch technology to sense the touch of a finger. A light touch is all that
is needed; the panel can’t differentiate between a light or hard press. The active area
for each touch control is in the center of the rounded gray rectangle to the right of the
LED indicator. For the slider, the active area is directly beneath the horizontal gray
lines.
To avoid accidental activation, each control must be touched for approximately half a
second before the touch will be recognized. Some functions, such as EZ trim, are
activated by a “long” touch of approximately two seconds.
The front panel is very scratch resistant, but can be scratched by hard or sharp objects.
Care should be taken to protect it. Clean only with a soft, damp cloth.

Input Selection
Each input can be switched between one of three modes. Pressing either input button
will cycle between MIC, LINE, and GUITAR. The default input type is LINE. Any time a
cable is unplugged from the input jack, the input will revert to this setting.
Changing the input type resets the input gain to 0 dB to avoid any potential audio
feedback.
Phantom Power
Phantom power (+48V) can be turned on when one of the inputs is set to MIC. If there
are two microphones connected, phantom power will be provided to both
simultaneously. To protect external equipment, this phantom power is disabled
whenever an input is set to LINE or GUITAR. In addition, phantom power will be turned
off when the Echo 2 first powers up.
Please note that the use of phantom power may require powering your Echo 2 with the
external power adapter instead of relying on computer USB power. Further details are
provided in the “Power”section of the manual above.
