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
Input Configure page (Analog Inputs selected)
{
p.80
}.
The
Analog Input (#) page
{
p.82
} for that channel appears.
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.
Adjusting the Trim (Analog/Digital)
There are two ways to adjust the input trim on channels. If you have multiple inputs, the
Analog/Digital Input
Trim page
{
p.103
} allows you adjust all of them from a single page. However, if you are making individual
adjustments to channels, the trim can be adjusted using the on-screen fader in the
Analog Input (#) page
{
p.82
}.
Adjusting the Trim using the Analog/Digital Input Trim page

Press the
Adjust Trim
button
on the
Input Configure page (Analog Inputs selected)
{

}.
The
Analog/Digital Input Trim page
{
p.103

0 dB
by pressing the
Clear Trim
button
. A dialog appears after pressing the
Clear Trim
button
requesting confirmation that you want to clear all of the trim settings.
NOTE:
If all channels are going to be set at the same level, you can save time by changing them at the same time.
Press
Select All.
Any change made to the level is applied simultaneously to all of the channels.
Pressing either the
STOP
