Tapping Sound from church speakers as aux input for streaming
Our Small Church has a PA system with controls in the front of the church. Because of COVID-19 we have been streaming services. Our Streaming is set-up in the Choir Loft with no direct access to the PA System in the front. We have been using a separate wireless system for streaming with sporadic results. There are speakers in the Choir Loft on a 70 volt line. Is there a way to tap into that resource and convert voltage? wattage? ohms? to use as an Aux Input Line to our mini streaming mixer? The distance from the PA System to Choir Loft is 80ft. We have limited access to any controls because it cost an arm and left for the Audio People to come out and re-adjust. We can only control Master Volume and turn Microphone on or off. Need a suggestion, driving us crazy for the last 3 months.

70 volt to line levels is possible. Devices exist for that. This scenario is a known one. web search for ’70 volt to line level’. Some even have signal detection and do not tun the unit on until they catch a signal from the 70 volt line. Not an expensive device. $20 to $100. Eg, Pyle appears to make an inexpensive one. When doing long cable runs, watch for grounding problems. Try to get the devices so they are on the same AC power line, so ground lift/differential, and thus hum issues are avoided or mitigated. Try running a long speaker line at the 70 volt level, over to the signal reduction device you buy, and have the signal reduction device on the same AC power as the PA system that is trying to utilize said signal. To reiterate...a long 70volt speaker line, with the conversion device right next to the PA input, powered by the SAME AC power as the PA. This should avoid noise issues, like hum and whatnot.

Therefore any answer will contain errors, from massive ones to simple ones. Just like your incomplete question. The answer I have supplied will ONLY give you the signal that is coming in from the 70 volt speaker line, to be injected into a PA mixer or the like. As that is the question you asked an answer for. |
Thanks for the earlier reply. I need to reduce the impedance or sound coming from the 70v audio transformer. We want to plug directly into a video camera located in choir loft. If the 70v speaker line is connected to the 5w connection rather than the 25w does the sound automatically get reduced? If i place a volume control on the output side for 4 ohm or 8 ohm will this control volume to a minimum of very low since the camera is only looking to have very low voltage/watts/ohms/decibels???? |
