French term or phrase: équipé en 3 voix
Hello again, I've looked everywhere for this but don't know what the term is for "en 3 voix". Could it be channels?
(I know it must seem that I'm not an expert on sound systems (which indeed I'm not) but this is a small part of a much larger document.)
Any help much appreciated (especially from the sound expert).

"Le système doit être en stéréo et alimenté par des amplificateurs de qualité, équipé en 3 voix et renforcé dans les sub-basses."

3-way system
Explanation:
With a home stereo, the power output from the one and only amplifier is divided (by something called a crossover) inside the speaker box so that the low frequencies go to the larger speaker and the high frequencies go to the smaller one (the infamous woofer and tweeter respectively). In a very fancy stereo, it may be split across 3 (or even more) speakers.

In a large PA system, the signal is split before the amplifiers (also by a crossover, but this one is an active crossover) and each speaker has its own amplifier. This obviously requires more amplifiers but a major system will have up to a hundred or so anyway. The advantage is that you only need one crossover (actually, two - one for left & right) and it works at the much lower amplifier input voltage so it doesn't absorb any of the amplifier's power.

This is actually a fairly mild technical rider - the requirements seem reasonable and reasonably flexible. You should see some of the one's I've had to deal with :)

Wait until you get to the bit about the brown M&Ms and no pork products to be present on site!

Notes to answerer
Asker: My goodness, thanks so much (once again) and for the most helpful explanation. I certainly know more about sound systems now and I'm sure all these future entries into the glossary will help some other lost soul.

Asker: Thanks for that info - "voix" is the spelling in the French text - not very helpful when trying to translate...

agree  Philippe Etienne: Should read "3 voies"

  -> That's right - I didn't even notice. I sense a Word automatic correction at work!

agree  Tony M: Absolutely! / fair comment

  -> No pro system uses passive crossovers. A 3-way system is active. I think the "system" here is the PA system. It has to be in stereo whereas the speakers themselves are not.
