QSC K8 Powered Speaker Explanation

0:00 This is video number one on this speaker here from a company called QS

Alright guys, this is video number one on this speaker here from a company called QSC. It's rather difficult to see the size of it but what I'm going to do is I'll just grab a random CD and show you there. It's quite a diddy thing but it packs a mighty punch. It's from a company called QSC, it's from the K series and this is the K8. Inside here we have a compression driver and also an 8 inch bass driver, thus the name K8. From a company called QSC like I said and this is a 1 kilowatt powered speaker. The term used powered or why they call it powered is because it's a 1 kilowatt powered speaker. Because it has an internal amplifier or amplifiers inside the box itself. Passive is the term used for a speaker that does not have an internal amplifier.

Right, let's have a look in brief at the back. This is video one, there will be more to come. So what you see on the back here is pretty much identical if not identical except for of course the numbers on the K10 and the K12 as well. So you can have a 10 inch and a 12 inch. 12 inch driver as well. So the 10 and the 12, the only difference being of course is that the bass driver is bigger on from the 8. This is an 8 inch, the 10 is a 10 inch and the 12 of course is a 12 inch bass driver. So what can you do with this little baby? Well what I like about it is you can have two audio inputs. So let's imagine now you're not a DJ, let's imagine you are a guitarist on the road and you've got your guitar and a microphone.

2:00 Separate gain control, also volume control

Don't panic. Okay, so what we can do, you can go in here with a quarter inch jack and you can use your microphone via that input. Switch there from line up to mic and then this is your gain control for your mic. Then you can go if you want to via input on the other side with your guitar. And what I like about the K12 and the K8 and K10 is you've got then a set of inputs. So what I like about the K12 and the K8 and K10 is you've got then a set of inputs. Separate gain control, also volume control. Some people call them attenuators. That will increase the volume on your guitar so you can do a nice mix here. And of course then an output here, a line out for post-gain mix. So that will give you the complete signal that you've dealt with here. So this isn't a power output, this won't power any speakers. This just gives a signal. That's really important.

So for example, if you go from the output of, and again, let's imagine we've got the microphone here and you go out of that into another K8. You will only from here get the output of the microphone. If you go out from this side into another K8, you will only get the output of the guitar. But if you go from the output of here into another K8, you will get the volume of the microphone. And the guitar. Not only that, these gain controls will let you not only increase or decrease the power, the output from this speaker, these also act like small gain controls from the signal out from the post-gain mix out, which means that you can have the microphone higher or lower, the guitar higher or lower, and so on.

3:42 What I do like about these is a couple of settings you can have

And then however these volumes are set will of course mean that the volume output on the other speaker, if you use the line out post-gain mix line out, you will get that volume. Now what I do like about these is a couple of settings you can have. You've got one here, HF, vocal boost and flat. What that does, it just gives the top end a nice crystal. It's almost like a warmer kind of sound. Without being overpowering. Deep here, three settings on the LF low frequency. Deep is giving you that more warmth kind of bass sound and I'd recommend you use that if you're only going to be using the K8s by themselves. If you want to, you can set that to norm which is normal. EXT sub means external sub. So if you are using an external sub, I highly recommend you switch to that because it means as you change the volume, you'll get a different kind of sound.

So if you are using an external sub, I highly recommend you switch to that because it means as you change the volume, you'll get a different kind of sound. If you turned the volume up on the K8, you don't have to worry about the bass because the sub bass cab will be taking over the bass, which means, that this little baby here can concentrate more on mid and top. Which in turn means it will be more efficient candidates but get a better clarity of high end. Which in turn again means you'll get a better clarity of high end. Which in turn again means you'll get a better clarity of high end. Instead of setting it to deep and having a bass cab into a low octave Instead of setting it to deep and having a bass cab into a low octave

Completely defeats the object okay front LED PWR means that the LED at the front of the speaker will shine quite brightly limit it sort of dull down and then off means it's off you can also go RCA in so let's say you're a bedroom DJ and you want a good set of quality speakers that you can take on the road as well then you can use just from your mixer RCA in you've also got red red and white so if you want to if you just got the one you can go red sorry I'll start again you can go from the output of the mixer left and right in and you will get the left and right signal through 1k8 so you've almost like got a mono stereo sound you've got the stereo coming in but you'll only get the one sound coming out because even you've got the one speaker

Alternatively of course if you've got two k8s you can go in left and then on the other side you could even go in left as well because if you're using let's say for example you're going right output on your mixer you could go into right here if you're going left output of the mixer you could go into right just so long as you go into the other speaker because you're still getting a stereo signal from the mixer and again if you're using the audio signal from the mixer you're still getting a stereo signal you could go into the other speaker because you're still getting a stereo signal from the mixer and again if you're using left of hand input you just use your right hand side you could go in left and then on the right hand side

6:48 Powered base, input, male version

Below the RCA in make sure that you use the gain control on the right hand side below the RCA in so in a nutshell on the left hand side you can see the gain control is responsible for the left hand inputs and output here sorry auf right side sorry dyslexic on the right hand side on the left hand side the game control here is responsible for the input input and of course the output now very quickly as well if you're using an external base cab a powered base cab then you will go into the input of the powered base cab out of the output of the powered base cab to the input here on the k8 k10 or k12 so just bear that in mind all right now i i hope that's been a help i'm pretty sure actually we think you know that's uh just to confirm so i

Don't confuse everyone yeah actually that's the input yeah i do beg your pardon so two mistakes there but rectified during the course of this video so you will go in here that is the input and then of course you'll go output via the male version so the um this is the female and that's the male version of rca all right this really is a quick exercise explanation of the ins and outs of the k8 also you can see and you can hear doggy in the background to apologize you can see here we've got this small sort of exit hole here and there's a fan inside there that's for cooling purposes so the last thing you want to do is cover that over and on and off i highly recommend as well is make sure that's turned down turn on and then

Of course you can turn the speaker up so for example let's say you've just finished your set and the volumes are up the game controls are up what you don't want to do is turn that off first ideally you want to turn your gains down first and then turn off at the mains that's pretty much it this is the qsc k8 if you want any more information check out the link in the description to the qsc website and i'll finish off with practice and enjoy thank you very much
