Passive inline audio device for adding input to audio channel?
I'm probably using a lot of the wrong words here, but I'm helping a friend who owns a gym add a wireless mic to their audio system so that when they're giving instructions they can be heard more easily, even while music is playing or while it's not playing.
Here's how the audio system currently works:
1. They control their music on an App from their Samsung tablet
2. The tablet controls their Sonos device. Audio does not stream to the Sonos, it originates on the Sonos.
3. The Sonos device is connected to a self-powered speaker on the wall via a stereo RCA to 3.5mm headphone jack wire.
4. This speaker is in turn daisy-chain connected to a second speaker a short distance away, also self-powered.
The Sonos device has an additional input, and you *can* plug a mic into it, but the Sonos device isn't capable of playing the music and the audio from the mic input simultaneously.
My current, best idea is for a device that I'm not sure exists, but I'm hoping people on this forum could tell me if it does. I'm looking for something that can sit inline between the Sonos and the powered speaker. This device can passively forward all audio it receives from Sonos and, if it receives any audio from an additional input, it could combine that audio. This secondary source of audio would be the input from the mic. Since the speakers are already powered it seems like any kind of miniature powered receiver might not work, not sure. Lastly, the final solution needs to give the user the ability to reduce the music volume, while keeping the mic volume constant, but this might just be something that could be controlled in the Sonos app, lower the volume on the app and that music volume would be reduced, but the mic volume would stay constant.
If it's of use to anyone, the Sonos model is the Sonos Connect and the speaker model is Electro-Voice ZLX-15P
Does anyone know of a device like this exists? I appreciate anyone's willingness to help.
