We have about 60 pcs tiny speakers strung up to 800+FT in our church Monastery. They were installed ages ago. Badly wired because the speaker wires are bundled with the 24 VDC wires. Changing wires will be prohibitive due to labor and cost. Can we use a Bi-polar capacitor in each speaker to block the DC in case the DC wires gets shorted to the speaker wires ?
Powered by a high powered car amp.
DC wires are about 3/4 " thick and the audio wires are #10 AWG or larger.
Using matching transformers to block DC is also labor and cost prohibitive.
Anybody have a suggestion other than replacing the wires and separating the 24 VDC wires ?
What do you think about about using Bi-polar capacitors to block the DC ?
Value will be around 100 uF @ 50 VDC to pass audio 400 HZ - 8 KHZ.
