A 100V line system sends audio at a higher voltage so one amplifier can feed many speakers over long cable runs. Each speaker has a small transformer with power taps (for example 3, 6 or 12 watts) that you set per speaker. The total of all taps must stay below the amplifier's rating. It suits shops, schools and hotels; for one small room with two speakers, ordinary low-impedance wiring is simpler.
Key takeaways
- One amplifier, many speakers, long cables.
- Each speaker has a transformer and a power tap.
- Add up the taps; stay below the amplifier rating.
- Speakers and amplifier must both be 100V (or both 70V).

04Frequently asked questions
Can I mix 100V and normal speakers?
Not directly. A normal 8-ohm speaker on a 100V line can be damaged. Use speakers with 100V transformers, or fit a transformer, on a 100V amplifier.
What is the difference between 70V and 100V?
They are two standards; many European and Asian products use 100V and many American ones use 70V. Match the amplifier and the speaker transformers.
How do I size the amplifier?
Add up the tap setting on every speaker, then choose an amplifier with 20 to 30 per cent more capacity.
