Signal flow & the console

Through the next few pages I will identify and describe the different areas of a mixing console and their possible use/ uses in a studio environment.

The prefixes opposite will be used in the following diagrams to show the functions of parts and show what the diagram should represent

The long column on the left hand side of the diagram above would be just one channel taken from a 24 track mixing console made by behringer. From the top of the channel the inputs are shown first.

On this diagram the switch (1) is to change the initial input into the channel from mic/line depending on which input is being used on this particular channel

Switch (1a) is used to drop the volume of the mic input by 20dB

The dial P2 is used to control the volume of the incoming signal into the channel and so therefore turning it to the right offers a volume increase whereas to the left offers a volume decrease.

This is the next section down in a channel as it is directly below the input settings and it is known as the Eq section. This is where the input sound can be altered through the desk by increasing/ decreasing the amount of bass/ mid /treble boost that are altered through the desk.

P (4) &P (5) are the higher end of the sounds and so moving one of these dials to the right would boost the hi end of the output sound and so would increase the hi-hats etc and generally make the sound more tinny.

P(5) & P(6) & P(7) & P(8) are the available dials to alter the mid range although this is a very wide mid range and so the P(5) would be more on the higher end of the frequencies and so would alter high notes although not a greatly as the P(4). P (8) is the same as P(5) but changes the lower end in comparison and so would be used to bring out a bass guitar etc. P (9) would boost the lowest of the bass end in the largest way and so would bring a bass noise right out or away in the mix. S (10) offers the user of the desk to bi-pass the eq section to give the original sound; this could be useful if in a mix you want to remove the eq that was boosting the bass quickly without the pitch change audible. S (11) is a low cut filter and can be used to cut off the lower bass end from a mix this can be used to cut the bass rumble etc.

This section on the mixing console comes just below the eq section (shown above) on each channel on the mixing console. It is used to add to the Sound input into this channel. The aux sends could be used to add an effect to the sound through an effects unit or a gate etc.
P (12) is the first dial in the aux send and would be routed to the first aux send/return section on the console and so the effect could be used on every channel if all dials of P (12) had be turned to ...
