Okay, let's take look at a digital audio interface. This is a 10-In/10-Out 24-bit/192 kHz capable interface. So, we've got a preamp section here with inputs, with these combo jacks that you can use microphone XLR cables for, or quarter-inch inputs, and then a Sensitivity, or gain control. So, once you have your microphone plugged in there, you can turn up the signal so that you get enough signals. You can also on this one, switch it from Hi to Lo-Z, so if you want to plug your guitar right into here, you can switch that so that it's at Hi-Z and plug your guitar right in there.
For other things like keyboard, synthesizer or drum machine, you can leave it at the Lo-Z. On the front, we actually have some digital Ins and Outs, and this is that ADAT Lightpipe input, which if you haven't seen, looks like this, and there's some Ins and some Outs. More or less, you hook this up here, and whatever your source that has that is you put this to the other end. This is nice, because it can transfer a lot of channels digitally at a high sample rate at that 192 kHz sample rate, which is exciting.
Then we can also select the actual sample rate we are working with here on the dial. There's also a monitor MIX if you want to determine how much the volume going to your monitor speakers in your studios just so you can turn up and down where you can quickly do kind of a pad which would probably turn it down to 10 dB, or so, just to make the room quiet for a minute. You can switch it to MONO, if you have to see if what you're mixing sounds good in MONO. You can switch the outputs that are normally are listening in stereo, you can just quickly jump to MONO and make sure everything in phase is okay.
Finally, there's a headphone output and a volume control for that headphone. So, let's go to the back, this is where we will see some kind of really interesting things, newer things. Obviously, you'll have power supply, which is going here, from, I guess, the left to right for you. We have the MIDI In and Out, and this is what you'll use to hook up MIDI equipment, which we don't have that cable around right now, but if I did, I could plug it in, it's that five thin cable with the funny holes that goes in and out. You can use this to go, send information in from like a keyboard controller, and back out to a keyboard controller, like a sampler.
MIDI is cool, we'll talk about that more in a different section. Then we have the FireWire in and out, which is how this interface connects to your computer via a magical FireWire cable. Then actually we'll go back and forth, there is actually two here, which is nice. I think you can probably run that in series. So, that's how this interface connects to your computer, and that's cool. FireWire is nice and fast, the new 800 is faster than USB 2, it's very cool.
Then you have Main Outs, the right and left, these would be what you would use to feed your monitor speakers. Again, those are controls on the front, and this knob here, more or less, and these kinds of options, are affecting these Main Outs here. Then you have a bunch of line Inputs and line Outputs as well, so if you have things like synthesizers, keyboards, drum machines, or line level devices, you can come into the Inputs, and you can also go out of the Outputs, which is nice.
So, if you are using this in conjunction with a mixing board, you can send signals in, go through the FireWire out to your computer, work, come back out through the FireWire, and then back out through these outputs into your mixing board to mix in an analog way, or to send signals out to a headphone mixer, really cool. So, that's the basic gist kind of features and functionality of a digital audio interface, this is a pretty cool. We also have a really pretty simple one, this is an M-Audio interface that really on the front it has a few things.
Input adjustment, which will adjust your microphone input, on the back there is a line input for guitar or line, switchable. These are your outputs, RCA's out to speakers. This is probably intended for not real super high level studio monitors, because most studio monitors, once you get in to kind of the more, midrange won't use an RCA input. So, if you have like a home computer system or kind of some slightly better computer speakers, this will work great for that.
On the front again, a headphone input and a master adjustment for that in a mix, between what's coming in and what's going out, and finally a Stereo and Mono button to change your output selection. So, you can get pretty simple devices or you can get more complex devices. There's lots of options out there, and it's exciting to see what you can do with them.
