Pastor Jim Posted January 24, 2022 Share Posted January 24, 2022 Can I wire our Klipsch AW 650's directly up to our church's 70.7v distributed sound system, or will I need a step down transformer to bring it down to 25v? Thx! Jim 1 Quote Link to comment Share on other sites More sharing options...
captainbeefheart Posted January 24, 2022 Share Posted January 24, 2022 You need to wire the constant voltage PA system through one of these: Secondary: Red to Black for 8 ohms wire to the Speaker Primary: White to Black wired to the 70v line Tape off all other connections and don't allow them to touch each other. https://www.parts-express.com/70V-15W-Line-Matching-Transformer-300-039 Quote Link to comment Share on other sites More sharing options...
Pastor Jim Posted January 24, 2022 Author Share Posted January 24, 2022 Thank you, Captain Beefheart! Someone said we'd "fry the speakers" if we just hooked them straight up. But isn't the incoming voltage controlled by the sound mixers outputs? Quote Link to comment Share on other sites More sharing options...

If your amplifier is a 70v constant voltage output your speakers wouldn't be happy with a direct connection, you cannot just directly hook it up to a normal 8 ohm speaker or damage will most likely ensue. If it's for just vocal PA uses and very light music then you can purchase the one I linked above. It sounds like you may be pushing music though these with the same system? If so and you plan to want to be able to crank the speakers to louder music volumes then you might want to get a higher powered one like this: https://www.parts-express.com/70V-100W-High-Power-Line-Matching-Transformer-300-225 Quote Link to comment Share on other sites More sharing options...
Pastor Jim Posted January 24, 2022 Author Share Posted January 24, 2022 Yeah, we push some healthy music volumes from the live band in the sanctuary. These will be going in the foyer so sound quality is important. Thank you SO MUCH for your helpful input and suggestions, my friend! May God bless you richly for your service to His Church!

Pastor Jim Ok then I suggest purchasing the 100 watt transformers, it will sound very full and detailed with those transformers as they are rated for full power between 40-20kHz which is really good, you will be very happy. God Bless you and your whole congregation and enjoy the music! Quote Link to comment Share on other sites More sharing options...
captainbeefheart Posted January 24, 2022 Share Posted January 24, 2022 Oh I forgot, the 100 watt model is really easy to install as there are only two primary wires which go to the 70v amplifier side and there are 3 wires for the secondary, use the two marked '0' and '8' to connect to the speakers and you will be all set.

Thx! Jim No you can’t. Aw 650 do not have a step down transformer. The ca-650’s do. You can buy 60 of 100 watt transformers from klipsch that will not degrade the sound.

Pastor Jim Posted January 25, 2022 Author Share Posted January 25, 2022 Thank you Chief Bonehead! I am such a novice at this tuff but knew our church needed WAY better foyer speakers than 50-year old Altas 8" boxes! Thank you and God bless!
