On smaller mixers the inputs are on the left of the mixing board and the master controls are on the right. In larger mixers, the master controls are in the center with inputs on both sides. The audio level meters may be above the input and master sections or they may be integrated into the input and master sections themselves
Channel input strip
The input strip is usually separated into these sections:
Dynamics processing (e.g. dynamic range compression, gating) Routing including direct outs, aux-sends, panning control and subgroup assignments Input Faders
On many consoles, these sections are color-coded for quick identification by the operator. Each signal that is input into the mixer has its own channel. Depending on the specific mixer, each channel is stereo or monaural. On most mixers, each channel has an XLR input, and many have RCA or quarter-inch TRS phone connector line inputs.
Basic input controls
Below each input, there are usually several rotary controls (knobs, pots). The first is typically a trim or gain control. The inputs buffer the signal from the external device and this controls the amount of amplification or attenuation needed to bring the signal to a nominal level for processing. This stage is where most noise of interference is picked up, due to the high gains involved (around +50 dB, for a microphone). Balanced inputs and connectors, such as XLR or phone connectors, reduce interference problems.
There may be insert points after the buffer/gain stage, which send to and return from external processors which should only affect the signal of that particular channel. Effects that operate on multiple channels are connected to the auxiliary sends (below).
