Hardware & signal path
Mixer channel
A channel is one vertical strip on the mixer and everything one source passes through: input select, trim, EQ, filter, cue, and the fader at the bottom. The controls act in that order from top to bottom.
In practice
A channel strip reads top to bottom in signal order. Fix a problem at the stage that caused it, not at the fader.
Build the habit of loading, setting trim against the meters with the fader down, then bringing the fader up — in that order, every time. It takes three seconds and it removes most level surprises. Use the filter for movement and the EQ for balance rather than the other way round, and keep the fader itself in its top third so you have somewhere to go in both directions when a transition needs it.

Why it matters
The top-to-bottom layout is not decoration — it is the signal order, and reading it that way makes the mixer explain itself. Trim corrects how the record was mastered, EQ shapes it, filter sweeps it, cue listens to it, and the fader decides how much of the finished result reaches the room. Anything you do lower down cannot undo what happened higher up.
That is why a distorted channel cannot be fixed at the fader. Once the trim has driven the strip into clipping, everything below is a level control on a broken signal, and the only real repair is several inches further up.
Frequently asked
Why is one channel quieter than the others?+
Usually trim rather than the fader: the records were mastered at different levels and the trim is what corrects for it. Set each one against the meters as it loads.
Should the fader be at the top?+
In the top third, not pinned. Leaving a little travel above means you can push a record slightly without touching the master, and travel below means you can duck without a jump.
Does the filter come before or after the EQ?+
On most club mixers the filter sits after the EQ in the strip, so a filter sweep acts on the already-EQ’d signal. It is worth knowing when a bass-killed channel still sounds full under a low-pass.

Channel fader
A channel fader is the vertical level control for one deck. The crossfader chooses between two sources; the channel faders decide how much of each is in the room, which is where most club mixing actually happens.
Gain
Gain sets how hot a track arrives at the channel before anything else touches it. Most club mixers label the same control trim. It is a correction for how a record was mastered, not a volume control for the room.
Signal chain
The signal chain is the ordered path a sound takes from file to room: player, mixer channel, master, amplifier, speaker. Each stage has its own level and can only pass on what the last one delivered.
Two-channel vs four-channel mixer
A two-channel mixer takes two sources and is built around the crossfader; a four-channel takes four and is built around the channel faders. The choice is about how many things you want playing at once, not about quality.
