Presets and Multiple
EF2201 Devices
If you have multiple devices in your system, save settings to a user preset (Presets 16-
47) on each device. Saving a preset will only save the preset on that particular unit.
Also, remember to set the P
OWER ON PRESET to the User Preset that you have saved
your settings to otherwise the device will revert back to Preset 0 (factory default) if
power is lost.

If you are connecting the EF2201 to a Vortex device, the default level of 0 dB should
give sufficient gain.
