Is FX send the same as aux send?
Aux sends are sometimes labeled with different names such as “effects send,” “FX send,” MON (short for “monitor”) or even “foldback,” but they all work the same way: They serve as a secondary output from a channel that routes the signal to a place other than the main left and right speakers.
Is FX send mono or stereo?
The bus appears at the console’s FX send output and can be fed from there to an external effects device. The return from the effects unit is then brought back into the console on the stereo channels. Each FX send is mono and features up to +15 dB gain.
What are sub outputs on a mixer?
A Subgroup is a mix bus destination where you can route channel outputs. The audio channels can be processed at that point with effects like EQ and Compression. Each mixer is going to be a little different in how many subgroups they may have.
Are aux sends stereo or mono?
Each aux output is a mono send. The effects returns are stereo returns. This is quite normal because, typically, you’d be patching a stereo reverb across them: taking a mono input to the reverb and creating a stereo return signal, for example.
What does AUX mean on a mixer?
An “Aux Send” is a type of output used on most live sound and recording mixers. It allows you to create an “auxiliary” mix in which you have individual level control over each input channel on your mixer to your “Aux Send” output.
What is FX send used for?
Why do subwoofers have 2 inputs?
Dual input allows the subwoofer an extra sensitivity adjustment. Normally, it would be enough to use a mono LFE subwoofer signal from its processor. By using both inputs with the same mono signal doubles the subwoofer sensitivity. This means that there is now only half the signal strength to drive it to full output.
How do you put a sub in a mixer?
To connect a subwoofer to your mixer you’ll need a crossover. So you’ll need to crossover the full range main mix outputs. Connect the main mix outputs to the crossover inputs. Select the crossover frequency.
Can you turn a mono signal into stereo?
One of the best ways to create fake stereo from mono is to make an M&S (Middle and Sides) stereo mix from the mono source. Take an aux output of the mono signal and route it to a digital delay.
