Mixing Desks

Definition Of The Mixing Desk; The mixing desk brings multiple sound source's/signals together to be mixed.

There are a few different types of mixing desks, Inline, Live, Split, Broadcast, and Matrix.

We shall take a look at each different type of mixing desk.

Inline Desk;

Inputs/Outputs and Monitor section are all in line (All in one channel strip).

In Record mode the channel fader receives mic or line input, and the monitor section receives the tape returns.

In Mixdown mode the channel fader receives the tape returns, and the monitor section receives mic or line input.

Basically vice-versa of the Record Mode situation.

Here are a few things that can be found in each specific section of an inline mixing desk.

Input Section;
Pan, Phantom power, Attenuate Switch, EQ, Unity Gain, Mic/Line Switch, Phase Reverse, etc.

Output Section;
Channel fader, Multitrack Assign, L+R Assign, etc.

Monitor Section;
Pan, Solo, Mute, EQ, L+R Assign, Output to Tape, Tape Return signal (Lets you monitor what is coming from tape), Monitor Source Select, Monitor fader, etc.

Master Section;
Master Source Select (Level of what you are listening to), Headphone source, Control room level, Auxiliary master level, Separate headphone level, Oscillator (Generates a tone to calibrate external devices such as a tape deck meter, compact disc meter, DAT machine meter, etc.) Master Fader (Controls the level going to the 2 track mastering device/s), Talkback microphone (For Communication to the live room, etc.), Auxiliary Master 1+2/3+4.

Benefits and Use's;
Can come in a wide variety of sizes from big to small, they are very versatile, and are mostly used in professional and home built studio's.

Live Desk;
A Live desk has no monitoring section or no tape return's.

It has got an input section, an output section, an auxiliary section and has group faders.

It only has one mode so record mode is the same as mix. So basically what you would be hearing live is what you would be recording.

Benefits and Use's;
A live desk is exactly that, it allows you to record exactly what you are mixing/hearing, it is used for live PA's at festivals, live gigs and concerts, etc.

They are usually pretty basic, and straight forward to use.

Split Desk;
On a Split Desk the monitor section receives the Mic and Line feeds (Returns).

In Mixdown mode the channel inputs will be receiving the tape returns.

On a split desk the inputs/outputs on the monitor section are separate with the inputs on the left and the outputs and the monitor section on the right.

Benefits and Use's;
More complex than an inline mixing desk, also a lot bigger than an Inline mixing desk and are mostly used in the more professional studio's. They are also very expensive to buy.

Benefits and Use's;
Usually lightweight, very basic and easy to use. They are mostly used in Television studio's, Night clubs, etc.
