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
Condenser microphones typically require power to operate. This is commonly known as
phantom power, or +48 volts. The Echo 2 can provide phantom power when one of the
inputs is set to MIC. To turn on phantom power, press the +48V button.
If there are two microphones connected, phantom power will be provided to both
simultaneously. To protect external equipment, phantom power is turned off whenever
an input is set to LINE or GUITAR. In addition, phantom power will be turned off when
the Echo 2 first powers up.
Again, please note that phantom power requires powering the Echo 2 with the external
power adapter.
If you're unsure how to set up your inputs, please refer to the following table:
