Enabling 48 VDC Phantom Power (Analog Only)

Some microphones require external power to operate. The Fusion supplies the full power and current allowed by
the phantom power specification (48 VDC up to 1.0 A). The Fusion does not supply 12T power, which is required
by some older microphones. If you use microphones requiring 12T power, check with your local audio dealer for
phantom to 12T power converters.
To enable phantom power, perform the following:
1. Press the Channel button on the
The Analog Input (#) page
2. Press the 48V Off button. The text turns red and changes to 48V On indicating it is active.
IMPORTANT: To protect equipment from damage, the Fusion does not allow you to apply power to any
channel set as a line-level input.
