Microphone Option Jumper
A plug on jumper sets the option required. Plug across the two
pins to set. Plug on to just one pin to remove. This keeps the
jumper available to be re-used later in the future if needed.
Phantom power 30V phantom power is disabled when JP1
is fitted. This is the factory default setting. Plug the jumper on to
JP2 instead if you wish to turn phantom power on.
WARNING Do not connect unbalanced sources or
cables to the XLR input when phantom power is applied. To
avoid loud clicks always turn the mic level down before
plugging or unplugging phantom powered microphones.
