[Music] [Applause] Hello, this is Sound Master. Now, people who do audio as a hobby probably don't have just one amp or speaker . So , as expected, I am piling up towers . Now, there are times when I want to hear a new sound by connecting different amps to each other . There may be times when you want to combine the warm and soft sound of a vacuum tube amp with the ample output of a TR amp, or when you want to listen using the digital input and Bluetooth function of a modern amp , and combine the sound with your existing vintage amp. So today , I will tell you how to connect the amplifier and the amplifier, whether there are cases where it is impossible to connect, and how to actually connect it, as well as the precautions . is a case that so many people ask . I think you might want to combine the soft, musical sound of a tube amplifier with the power of an existing tr amplifier. Most of the vacuum tube amps you have are probably in the form of an integrated amp. EL34, El84 , [music] 300b, 6N2 Most of these tube amps you have now are in the form of an integrated amp composed of a first tube, an output tube, and a rectifier tube. Unfortunately, this amplifier can not be connected to the front of the existing tr amplifier because this vacuum tube amplifier does not have a pre-out terminal or record-out terminal . As you can see in the picture, there is only one speaker output terminal and then an RCA input terminal on the back. Well, there are cases where there are multiple input terminals, anyway. Most of the vacuum tube amps I've seen have no pre-out or line-out .so you cannot connet it to other integrated amp. Tube pre-amo like marantz 7 can connec to integrated amp , because it's pre amp, so it has pre-out terminal Yes, so if you connect the preout terminal to the line input of the other integrated amplifier, you can now connect. Now, is there no such way? In this case, the reverse connection is possible. Now, put the TR amplifier in the front and connect the vacuum tube amplifier to the rear. Now, in this case, connect the line out or record out of the integrated amplifier to the input terminal of the RCA input of the tube amplifier. In this case, the tone control such as the volume or tone control of the integrated amplifier has no meaning anymore. In the end, the source is received as it is and passed on to the tube amplifier So, the int amp is just functioning like selector.and the tube amp amplifying the source as power amp. this case has some merits, you can receive digital sources via integrated amp like those bluetooth , DLNA, streaming music... . . However, the integrated amplifier at the front stage does not have any functions such as volume control, tone control, etc. in this case the int amp returns the source right just after coming in from the line in. Second, connecting pre-amp and Int-amp In this case, sometimes I bought a preamplifier later, but I like the tone so much that I want to connect it to the existing integrated. Now, in this case , there are two ways to connect depending on whether there is a main input terminal on the back of the integrated amplifier or not. It is divided two case. First, if there is a main terminal now, the out terminal of the pre-amp, the the pre-out must be connected to the main terminal at the rear so that it can function properly. If there is no main terminal now , you can connect line out to any line input terminal . If you connect it to the main terminal on the right side, it will now be connected to the main amplifier. If there is no such terminal, you can now connect the line input on the right side to the input terminal on CD DVD... . If you look at the terminal, there are two types. On the left, there is the small RCA terminal, which we often see, and on the right, there is a balanced terminal with three holes. I mainly use RCA jacks a lot now, I use them a lot, but now, when I look at some high-end amp models, they have a balance jack, so I can use both balanced and unbalanced, that is, RCA with one hole and the ground that surrounding part on the outer surface corresponds to the ground signal, and the terminal entering the hole in the middle is the part where the actual signal enters . Balance terminal The balance terminal you see on the right side has three wires. It has three holes, right. One is ground now , and the other two correspond to signal lines. Since the signal is completely separated and the signal is composed of two strands, it has the advantage of being able to separate various noises coming through the ground line. Since the ground line is separated, you can think of it as being virtually unaffected by noise coming from the ground. The second is the case of connecting the integrated amplifier and the integrated amplifier or now connecting the integrated amplifier and the receiver . I wonder if there is a case of connecting like this . There may be cases where you want to do this. Yes, even in this case, it is divided into two cases. It is divided into a case with and without an integrated amplifier or receiver at the rear stage. You can connect it to the line source. In this case, just because there is a main terminal, you should not connect the line source to the main terminal at the front end . I think you probably don't have one, but I'm telling you just in case. As I said before, the line -out or record-out of an integrated amplifier Because the source source is output at the maximum volume as it is, the volume cannot be adjusted. In other words, it is supposed to come out at the maximum volume of the source source . Now the sound comes out, and it will make a tremendous sound . You will be surprised, and if you do it wrong , the speaker can be damaged . Since there are many different types of amplifiers, I think it would be okay to try them by connecting them in a way that can be combined by taking advantage of the strengths of each . Now, I'm done with this video, and I'll see you next time with a better video. Thank you.
