Can an old fashioned extender come with speakers? Can an old fashioned tape recorder be converted in

Can the teacher's frame mount have a stereo? I feel like I can just take it up for an hour.

Yes, as long as they can be connected to each other, the output of the signal can be realized, and there is no technical problem.

The common one is a passive speaker, that is, one without an amplifier, and one with an amplifier is called an active speaker, that is, if there is a power cord, it is an active speaker with an amplifier.

Can an old-fashioned amplifier have speakers? But yes, all of the related interfaces are an interface within a range that can be used.

The old dual-card recorder also has an audio output jack, which should have a line output or headphone output jack or something, and the socket is also a standard stereo pin jack, both of which can be connected to a computer or an active speaker.

Yes, but the impedance mismatch affects the output power.

If you use a 16 ohm file, it is better to use two 8 ohm speakers in series, so that the impedance is matched.

The 250 euro range is not needed. This gear is set up for long-distance broadcasting. It can only be used by impedance transformation.

If you are an old-fashioned ATM, you should be able to talk about the impression of the first time.

Yes, the teacher's amplifier can be equipped with a speaker, which can further improve the function of the attack.

Generally, you can, but some require a plug change.

Hello:——1、Whether it is an old-fashioned TV or an LCD TV, it cannot directly drive (directly with) the speaker. Because the TV does not have a power output jack,Only line output,Models with headphone output function,The power is also very small,Nor can it be directly with speakers。

2. The correct way is to use the amplifier to drive the speaker. The source is taken from the TV's audio line output.

3. For speakers with low power, you can use the audio amplifier of the TV to promote the speaker playback. However, you will need to install an outlet on your TV yourself.

There are several power amplification power tubes, and if it is 8 high power tubes, it may be more than 100wx2 (8 ohms) of output power.

If there are only 4 high-power tubes, the output power is not 100wx2 (8 ohms) but 50w-80w (8 ohm output power. It can only be equipped with 30-40W rated power speakers - impedance 4 ohms - 8 ohms.

The maximum power of the speaker is the power that needs to be --- power amplifier, 100wx2-8 ohm power amplifier can be equipped with 40-60W rated power speakers. The speaker is rated at 40W, and the maximum is 80WRated at 60W, the maximum is 120W

The rated power of the speaker is 50W - the maximum power is 100W, with 100Wx2 (4 ohms and 8 ohms power amplifier corresponding to the impedance matching is very good).

Except for large stage professional speakers, it can be equipped with all home floor speakers, KTV private room speakers, and small bookshelf boxes. When equipped with a small speaker,Turn the volume to the minimum before turning on,Gradually amplify the sound,Not a special professional speaker does not need to look at the power。

You can use any speaker at will, just don't be too big.

I'm going to test it, and I'm going to use a universal meter to repair electrical appliances.

It can be changed. If there is a line input socket, it is best to do it, just connect it directly. If you don't have it, you need to know a little bit about circuits, and it's very simple.

1. If it is a cassette recorder and find the transfer switch for radio and playback, the signal is converted from here and then sent to the power amplifier.

2. The easiest way: find the volume potentiometer and put the signal cable directly to the potentiometer input.

Find the tape recorder amplifier manifold, note down the model, go to the Internet to find a pin definition, find the input terminal, disconnect the input terminal from the pre-circuit terminal, lead out the left and right channels and ground wire from the input terminal to connect a headphone plug, and fix a tape recorder housing, with two male wires can be connected.

Find the volume potentiometer, put the signal cable directly to the potentiometer input, and cut the other end with a wallpaper knife (printed line), otherwise there will be noise.

If you change the amplifier circuit of an old radio, it will also make the audio signal input part.

It seems that you are not a welder faction, it is more difficult!!

It can be changed completely! But I recommend not using the power amplifier circuit inside, the old power amplifier effect is not necessarily good.

I suggest that all the speakers inside be removed, and the speaker cabinet should be designed and made from the wood of the original cassette recorder, and then a good crossover should be designed and debugged. Go to the electronics market or buy a power amplifier board with enough power. Combine it to create your own set of speakers.

I had this idea at first, but then I found out that the speaker in the tape recorder had broken and the paper tray had broken. So later, I didn't use anything in it, but bought a few sets of speakers again, designed a pair of three-way passive speakers by myself, and it took 2 months to debug the crossover (now the pair is in the living room, with a volume of 29x45x69cm). It's just that in order to be this pair, it seems that I spent more money and energy than buying a pair of speakers, and the copper wires used in the crossover are more than 100.

Are you going to make a 130w one? First of all, I'll give you a 30W mono OTL power amplifier circuit diagram, which is generally available at home Dual channels add up to 60W, and the components are still easy to find, buy a multi-purpose board to make it

You want ready-made words.

It's not that kind of low-power amplifier.

But I'll tell you a solution.

Buy an active speaker with a channel channel.

There are two outputs.

Swap those two little speakers for your Pioneer speakers.

No, it's fine.

Of course, there are 100 to several thousand active speakers** for the channel.

Look at what you buy for yourself.

Buy a *** with an amplifier, go to the mall to see, ** not expensive, just replace the two small speakers with it.

With Zhongshen 99B power amplifier, the effect is very good, if you want to connect ***, you can buy a lotus.

You can remove the horn to see if there is a logo at the magnet, if you don't see how many inches your horn is, there are several such speakers in a box, generally the power of the 6-inch speaker is about 50w, and the 8-inch is about 60 to 100w.

It's not as delicate as it says, it's pretty much fine. If the power is not indicated, you can estimate the power of the speaker by looking at the total power on the back of the machine (this must be there), or look at the size of the speaker to estimate the power. The power of the power amplifier should be greater than the power of the horn.

Your speaker speaker can be detached to see how many watts of power is behind the speaker? How many ohms is the impedance?

If there are no parameters, just look at what is the diameter of the magnet of the horn?

This is a stage amplifier, with a large output power, with 200-300w 8 ohms 15-inch stage speakers are better, the sound quality is slightly coarse, ** cheaper, the new 400wx2 8 ohm professional stage amplifier can be bought for about 1,000 yuan.

Professional stage amplifiers do not have good sound quality of home HIFI amplifiers, 100WX2 8 ohms of home HIFI amplifiers cost more than 1,000 yuan, and 200WX2 8 ohms cost more than 2,000 yuan.

There is no 400wx2 8 ohm amplifier for home amplifiers.

In addition, you can't buy a home speaker 15-inch professional stage speaker,That speaker is a stage singing speaker,Good midrange,Poor bass。 The sound quality is rough. But it's good with a stage amplifier == suitable for singing and propaganda work in the square and on stage.

Combined power amplifier, the power is very high, and the speaker within 300 watts is no problem.

The power of the satellite box is a bit small, and it is estimated that the power of the main box will not be too large, so you can consider buying an active subwoofer with an amplifier to use it.
