At the righthand side of the interface, FabFilter Pro-MB offers a high-resolution output level
meter. At the top of the meter, the maximum output level is displayed together with a clipping
indicator. Simply click the level reading to reset it. Note that the level meter uses the gray
display scale, ranging from -100 to 0 dB.
At the right bottom of the interface, you'll find the bypass, mix, input level and output
level controls, all accessed via a single output button. As soon as you hover the mouse above the
output button, a panel will pop up, giving you access to the following settings:
The InputLevel/Pan knob at the left adjusts the level and L/R
panning of the input signal before any processing is applied. You can use this as an
alternative to changing the threshold of all bands.
The OutputLevel/Pan knob at the right adjusts the level and L/R
panning of the final output signal. This lets you compensate globally for any gain added or
removed by dynamics processing.
The Global Bypass toggle button to the left of the Mix button bypasses the
entire plugin. While most hosts already provide the ability to bypass plug-ins, our internal
global bypass feature is guaranteed to correctly compensate the latency of the plug-in and it
also applies soft bypassing to avoid clicks. While the plug-in is bypassed, the display dims
and a red light glows in the bypass button itself. The top of the output button in the bottom
bar is also highlighted in red.
The Mix slider enables you to mix between the dry and processed signals,
scaling the overall dynamic and static gain changes for all bands. Because the Mix slider
ranges from 0% to 200%, you can also choose to increase overall gain processing instead of
fading it out!
Tips
You can directly adjust the mix, input gain or output gain by clicking and dragging the
button text vertically. You can also double-click the button text to directly enter a value
using the keyboard.
If desired, you can make the output options panel 'sticky' by clicking the output button
once. Click it again to hide the panel.
By holding down the Alt key while dragging, input and output level can be adjusted
simultaneously in the opposite direction.
You can reset the level meter peak read-outs by clicking them.
