Feeding Audio from Laptop into Chapel Sound Systems

#1

Post by brandonm35 »

I regularly Stream my Ward's Relief Society and Sunday School and am often asked to show videos during the lesson, I normally just grab one of the hand held mic's from the chapel and set near the tv speaker to pickup the audio, what would be the cheapest and most effective way to get the audio feed directly into the microphone hookups in the classroom (which are the same type as the chapel). so that the sound is good quality.

I know there are devices (Audio Mixers) of some sort but not sure which one would be best or most cost effective to use and have with me at all times just in case.

I usually play soft inspirational Sunday Music before the classes start as a way to bring the spirit in before the classes start and would love to be able to do it through the ceiling speakers easier than just using the hand held microphones.

Your meeting house should have a "crab box" that has a number of connectors that will adapt any headphone or line level out to an XLR microphone connector.

I'd suggest hunting the library, clerk's, and bishop's offices for a zippered case.

Example: EJ-10

Would something like this possibly work, to simply play audio through the ceiling speakers/Audio system in the classrooms via the mic input in the walls.

We do have a Crab Box of sorts but it's not available nearly every time I need to use it, if something like this would work instead I could have it on me at all times and be able to use it at the drop of a hat if needed for any class I happen to be streaming and they need audio from something played through the speakers in the celiing.

No. First of all, I think you'll find the 1/4 inch diameter plug far too big to connect to your laptop.

Second, if you switch to a 3.5 mm plug, you'd still need some kind of attenuator to step the laptop's headphone output down to mic level. Otherwise, you're going to get some loud noise that will ruin the mood.

Lastly, you probably want some kind of isolation to prevent introducing hum or buzz.

Looking over past threads, I see where people were looking at devices running $50-80.
