Amplifier vs. Preamp: What's the Difference?

Solved

Hello, here is everything in the title :)

2) I have two turntables connected to my system, so they use the speakers of my system:

- Why is the sound coming from the speakers when I use my turntables so low even when I turn the volume all the way up?

- Can I buy speakers independently of a system and connect them to my system?

Thank you very much, have a great day.

    Because the sampling frequency that comes from the turntables is much less powerful than that of the amplifiers, so you take the power from the turntables, that is, the least weak power...

      You need to put an amplifier between the turntables and the speakers...

    Every now and then the phono input on your amplifier is adjustable to .5 volts or .7 volts. I believe it's been a while since I last used it; there is a switch at the back of the amplifier. Otherwise, connect your turntables to an audio mixer that allows you to increase the audio signal. But connect the mixer to the auxiliary input of the amplifier.

    Very well, so in my case, my speakers are preamps and my amplifier is an amplifier :) ?

      Tes enceintes sont des transducteurs qui convertissent un signal audio en son. Elles ne sont pas un préampli. Il y a des enceintes qui sont munies d'un ampli intégré, donc il y a un préampli et un ampli à l'intérieur, et il faut les brancher à une prise de courant. Un préampli augmente l'amplitude d'un signal audio que l'on branche à son entrée, c'est donc un gain en tension ou voltage. Un ampli de puissance ou ampli reçoit le signal du préampli pour lui donner un gain en courant.

    Plugging in other speakers won't really solve your problem. The output signal from your turntables seems too low. Normally, home amplifiers have suitable phono inputs. If you're using a mixer, it can boost your input signal, but be careful—if you turn it up too much, your sound will come out loud, but you'll have distortion.

    But my speakers are amplifiers?

    Can I buy new speakers and replace the ones I already have and connect them to my system? Does it work if it's not the same brand?

    How to avoid distortion?

    What does an amp look like (I have a bass amp, but I doubt that's what I need to connect to my system....)

    What does a preamp look like?

    If your speakers are amplified, they are connected to your sound system with RCA cables (red and white). If they are connected with thick cables (No. 8, No. 6, or others), they are regular speakers. A home amplifier is a metal box with terminals.

    Il existe des systèmes d'amplification avec amplificateur de puissance intégré ou séparé. Un amplificateur de puissance intégré signifie que tout se trouve dans le même boîtier et sur la même carte de circuit. Un amplificateur séparé est soit dans deux boîtiers distincts, soit dans le même boîtier mais avec deux cartes de circuit séparées, une pour le pré-amplificateur et l'autre pour l'amplificateur de puissance.

    You can change your speaker system (speaker) to any brand as long as your connection cables are similar. Is your basic amplifier a home theater subwoofer?

    Well, for the moment I have:

    My turntables connected to my system (which includes 2 speakers) my system = MM-ZJ8 Samsung

    If I understand correctly, I need to add one or more amplifiers to be able to turn it up louder = add amplified speakers, is that right?

      I saw it on the internet, it's a mini stereo system. Everything is in one block with two speakers. Not much to do. A mixer might be a solution since it has an adjustable built-in preamp.
