The large VU meter displays the output level as VU value (energy) and peak value (peak level).
To visualize levels above +5 dB, the sensitivity can be reduced by -10 dB.
The VU meter can be switched to display the gain reduction of the compressor.
External Inputs
Each Frontliner module has its own balanced inputs and outputs. Thanks to a sophisticated circuit logic, you can integrate all elements of the Frontliner like single devices into a studio environment. However, you can also group them as you wish or define insertion points at each interface.
If you think of the respective Frontliner modules as analog plugins, the added value becomes clear, which makes the Frontliner a versatile analog processing station in addition to the classic recording channel: DAW-based studios in particular are enriched with a first-class recording front-end and can also access high-end analog processors for the essential signal processing during mixing.
