Hi all.
I recently built a 5 channel audio mixer. Inputs are all unbalanced. It has Left & right output jacks on the rear.
All jack sockets are steel Switchcraft types.
Unit has an internal transformer power supply with mains safety earth tied to the chassis.
My question is, will it be OK to connect the input &output socket grounds directly to the chassis or will I need to isolate all the sockets from the steel chassis?
To be honest, I have already mounted them directly without any audible issues. Im just curious about the proper way of doing this and the theory behind it. The output of the mixer is connected to my audio power amp and speakers. Any help appreciated!
As a side note, I have noticed that many commercial audio mixers on the market, have all the input jack sockets (line inputs) grounded via their mounting nuts etc.
