Video: Channel strips

Okay, let's take a look at the Channel Strips section, and I call the channel strips section, because like the inputs it's one set of controls repeated for each track. So once you know this one set of controls, you know the whole board in terms of the channels. So let's just take one and break it down. We will start with what we call Auxiliary sends. On this board there are two and they are color coated to be red. You can use this to send the sound in this channel to another destination, you want to set up like a headphone mix of the incoming signals, send them out to a separate output, and you want to use kind of a different sets of balances, you have your drums, your snares, your vocals.

Channel strips

Okay, let's take a look at the Channel Strips section, and I call the channel strips section, because like the inputs it's one set of controls repeated for each track. So once you know this one set of controls, you know the whole board in terms of the channels. So let's just take one and break it down. We will start with what we call Auxiliary sends. On this board there are two and they are color coated to be red. You can use this to send the sound in this channel to another destination, you want to set up like a headphone mix of the incoming signals, send them out to a separate output, and you want to use kind of a different sets of balances, you have your drums, your snares, your vocals.

You can use these to send that out to a small headphone amplifier, then give all your musician's headphones, and we can set up a different mix than the levels we are using to record with so that's convenient. You can also use Auxiliary sends to send to delay in it, some reverb in it, if you want to add some effects to the overall mix, so it's convenient that way. But these send things to different outputs. Next we have the EQ section, on this there are three dials, the High, a Mid, and a Low Frequency. Basically you can boost or cut, and it tells you what frequency that boost are cuts at, here on the High it's 12k, 2.5k on the Mids, and 80 hertz on the Low.

Dead center on these knobs is what they have a U, which is Unity, which means that you are not adding or decreasing anything. It's right there, the signal is just passing through and being unaffected. If you kind of get to the right, you are boosting that frequency, if you kind of get to the left, you are cutting that frequency. And then it shows the maximum you can boost, the cut here, it's -15db or +15db. So you can use this to EQ your sounds as they go through the board, it's very convenient, use this before you record, use it when you are playing back different tracks and things like that.

That's the EQ section. Now we have the PAN and the MUTE section, PAN is balance, it's the right channel and the left channel. So if you want to set up a stereo mix, and you want to set up a situation where you are only hearing certain instruments and certain sides of the stereo mix, you can use these to PAN things, you can bring two tracks in, like two guitar tracks and PAN them hard left and right and they will sound great, you do an electric on side and an acoustic on the other. So that's what panning is. Then there is a MUTE button, and that when you push it in, silences the channel, no matter where any of the other controls are, that makes all the sound that's flowing through this channel to stop, and it cuts it off.

SOLO is the opposite, push that in, and it silences all of the other channels and makes only this channel audible at that moment. Finally, there is the Fader. Now the fader is not exactly a volume control, it's more or like a pass through device, and on this board you will see again a U and kind of a center section. When the fader is placed at that U or Unity Gain, that means the level of the signal coming through here isn't being increased or decreased. But this kind of affects how much gets through, and using this is how you do your mixes and set your levels.

That's pretty much it for the Channel Strip Section. Now we will take a look at the Master Section.
