Why shops, hotels and schools wire speakers on a 100V line, and when 8-ohm wiring is simpler. Bad sound makes good speakers sound unprepared. Read on: it takes a few minutes and could save you a lot more than that. **In this guide you will see:** - One amplifier, many speakers, long cables. - Each speaker has a transformer and a power tap. - Add up the taps; stay below the amplifier rating. Quick answer 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.

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. ## Why customers choose Qyvea **Genuine brands**: Manufacturer warranty on what we sell, so you are not gambling on the box. **One team, start to finish**: The people who advise you also install and support it. **Fast answers**: WhatsApp replies usually within 30 minutes, and delivery within 24 hours in Nairobi. **Easy to buy**: Pay by M-Pesa, bank transfer or card.
