ROOM (3)

knob for more room ambience, or decrease for a drier close-mic tone.
When ROOM is adjusted, the RIG LED illuminates in amber, indicating the ROOM
amount is different than the value stored in the active RIG preset.
ROOM sounds are heard in the LINE / MON, HEADPHONE, and S/PDIF outputs, but not
in the TO SPEAKER output.
Tip: ROOM settings can be edited and stored with the OX software app.
