Use for 2nd pair of input terminals on PA speakers?

Hi guys,

I recently bought a pair of SLS LS8695 speakers. These are passive 2-way speakers with a column of ribbons (hifreq) and a column of woofers (lowfreq) in a single box. They were originally marketed as PA speakers. I'm not familiiar with pro-gear and I had initially expected two sets of speaker bindings, one for high and one for low. Instead, I found that there are two sets of NL4 connectors.

I can't find the manual for these speakers online and I can't understand why there are two sets of NL4 as each NL4 connector is 4 pin. I would have thought that one NL4 is good enough to carry a high/low pair. Can anyone comment on what the second set of NL4 would be good for and how (not) to use them?

Thanks,

Zhao
 

I saw found this "manual" as well, but it's actually a brochure and I wasn't able to get a sense of how to use the 2nd terminal from it.

When you mean daisy chain, do you mean that both inputs are wired to the same lines inside the box? So if I have two speakers A & B; I stick the amp(s) into terminal 1 of speaker A, (daisy-chain) link terminal 2 of speaker A into terminal 1 of speaker B, the amp is now seeing seeing two speakers in parallel?

Thanks for your help.

Yes.

PA speakers are often used in multiples, in parallel, so the extra pair of connectors simplifies setup.

They must sound good, but I have strong reservations about possible sensitivity and max SPL achievable.

Enough for home use, no doubt, but not so sure about a regular large space venue.
