PC Recording from AMP (Sound System) - Reduce Static/Volume

[mh348]

We busy with a Project where we have to record & stream Audio from a Sound system. There's currently 2 locations that we need to setup, One is going to be recording the sound using a Raspberry Pi and the Other a Normal Windows PC. So far on the location with the Pi we connected the sound from the Sound System (AMP) but because of the volume it's causing static/noise on the recording.. We can't adjust the volume on the sound system as that will affect the speakers, so we need a way to only lower the sound on the line connected to the Raspberry Pi.

Any suggestions on how this can be done? Maybe a small mixer or a stereo cable with volume control? will this work?

What output from the amp do you have the Pi connected to?

Look for the pre-amp outputs and do not connect directly to the speaker outputs.

How is it connected to the Pi? It's my understanding it doesn't have audio input.

Either way I'd just use an external USB recording interface, PC's are awfully noisy (rf noise).

What sound desk do you have?

If you have a digital desk with spare outputs, you can always duplicate your output and record directly from that instead of from the AMP. This is how I do it at our church and it works great. I do have to mention that we have an external interface (M-Audio Delta 66) and we can set the input level on the PC.
