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 ;)

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

Many Thanks. I just easily connected a Bogen C 60 P.A. amp to my 12" Celestion 70 / 80 guitar speaker and ....suddenly : Music🎼🎼🎼🇨🇦🍁

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.

Question:
0:50 Does the 100v line cause electric shock if someone touches the 100v terminal screw ? Thanks for the video.

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.

Why are the speaker wires not connected to the “OHM” conn and either the 4 or 8 terminals..? Is that an 8 ohm speaker. Thanks

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?

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

[alexyfrancis]

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

[graypaul]

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

[kermets]

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

[jonathankeenan]

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

[rafaelrivera]

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

[Midelle]

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?

[jazzmood]

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

[IntelligentElephant]

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

Connecting a 70/ 100 volt #speaker to a public address #amplifier can be a real problem if you don't know which terminals to use. This is a short instruction video shows you where to make the connection. #Constant-voltage speakers need to be carefully wired so you don't overload the amplifier.

[Simone-qrmq]

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?

[jazzmood]

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.
