So I wanted to do a little video on pre-fade listen, I’ve already explained it another video that pre-fade is anything before anything’s affected by the fader.
The gain of an input is adjusted by two controls, Trim and Fader. This two-stage architecture is identical to the topology of large mixing consoles and provides a great deal of control. Trim is often thought of as a coarse gain control and the Fader as the fine gain control.
The Fader is the primary control used while mixing, and it affects the level of input signal routed to all post-fade destinations. Use the Fader control to make fine gain adjustments.
This answer will change drastically depending on your line of work but for me I can have the all in one unit solution a then if i need to expand i can put a mixer in front to interface with it as a recorder.
I haven’t had much real world experience with them but i think for the price I would air more on the side of investing the the Sennheiser G3 set. For the expense and amount of uses from them I don’t think that much of them.
