Connect the amplifier to 70/ 100 volt speakers

I have bought a MISTUBA

  the transformer inside has been burnet, could you tell me what is the rated output power,voltage of the transformer used so I can buy.

I have some old Argos intercom speakers with transformers attached to the speakers like the one you show. I build my own low power amps for mandolin and acoustic guitars. I have hooked up my amps outputs directly to the speakers. I have been unable to use transformer. Is this because I need an amplifier with the proper 70/100 volt outputs? Any way to take advantage of the output transformer? I typically have a 12v power supply feeding a LM386 or LM380. 1 to 3 watts output. Standard mono output.

I have a ADS 120 w mixer amp with 100v and 70v. Everything works on the 4ohm -16ohm speakers post. But I'm wondering about the 70 and 100v terminals. I didn't feel any jolt or anything nor did it indicate anything on the my Volt meter. I haven't hooked up my 100v speakers to anything yet, but shouldn't that 100v be live all the time? Or does it need a speaker hooked up to it?

Hi Gary, my question is, I have 10 toa pc-1869 ceiling speakers and I want to install them in the patio ceiling, now I have a Sony STR-DG510, can I wire them to this avr or do I need a 70/100V amplifier. Thank you for your time Gary.

If i connect a speaker to the 70V line can i still use the 4Ω-8Ω-16Ω outputs?

Sir AMC 60 Australian monitor how can connect speaker

Good video

Hi Gary, Does connecting the + and - the wrong way round cause any issues?

Hi, is the ACM120 and 1 or 2 channel output amp ? could i run hifi speakers on it....cheers

Por favor como conecto 2 bocinas jbl 8128 a mi amplificador? Mil gracias por su valiosa respuesta.

How to connect the ampilifier to the mixer

Hello sir
How to make 100volt amplifiers

Nice explanation, thanks!

Hi.i have 20wats speaker then mention 500ohms/500ohms. So where i have to connect. How many ohms

Thanks

Hi Sir, what is the differences between 70v and 100v line...

When to connect with com 4 ohm/8ohm and when to connect with com 70v /100 v i don't know

How to connect for 2 100v speaker?

HI, I bought 4 jbl 26CT 70v / 100v speakers, I want them for my audiovisual room at my house, which amplifier will you recomend me?

is it possible to buy a 70 or 100v out put transformer and connect it to an hi fi amplifier to allow it to drive 70 or 100v speakers?

how do you connect additional speakers?

how can i hook up a 70v speaker to a professional type amp example (qsc RMX1450 amp)

so where do I go to learn how to connect regular 8 ohm house speakers to the 8 ohm side? what if I want to connect more than one speaker

thank you!

how would you wire a SNOM device on the back of the bogen AMP?

Many thanks for you very basic and useful video. Expecting more video from you.

I have one full operational 1959's Philips tube amplifier type EL 6425 but there is no available information about the polarity of the line output transformer (70/100 volts). The original output connector was lost long time ago and the internal cables don't give me a clue about that. Neither the transformer or the internal output impedance selector. I can't find a clear back image of one original amplifier and check it. How can i recognize the polarity of the output transformer, without using special tools? I believe firmly in correct phasing of loudspeakers but in this case it's hard to know exactly what i'm doing. Is it my imagination or i saw somewhere written on the web that says that this type of transformer doesn't require to pay attention to that detail? Thanks in advance. Macedo Pinto, Portugal.

Gary: I need one information. Could you please help me?

hi would you please help me to connect 8 speakers in the same amplifier (100v)
thank you

hi there can you tell me how to output xlr to 100v line speaker.what pins on the xlr are needed to be connected

are those plastic terminal covers necessary for 70 volt installs I have an amp without those so do you need them

pls , how can i connect an amplifier to another amplifier in a paging system? in a distance about 90yds, both are work in 70volt connection and locally works perfectly with a mike  locally, but i connect in paralel the microphone an the distortion is very high.....thanks for your videos...............

Great video, thanks Gary.

Another great video, and the production is improved too. Good job Gary - if Apple is looking for somewhere to film their iPhone 6 videos, I'll point them your way ;)
