This Symetrix Jupiter 12 offers 12 analog inputs and 4 analog outputs, along with 2 control inputs and 4 logic outputs. Note that it doesn't come with a power supply. The first two mic input connectors are dented, but the inputs still work and phoenix connectors can be installed.

Using the Symetrix Jupiter 12 is straightforward. Connect your audio sources to the 12 analog inputs and your output devices to the 4 analog outputs. Use the 2 control inputs for custom control set - ups and the 4 logic outputs for logic - based operations. Remember, you'll need to provide your own power supply as it's not included. When it comes to the dented mic input connectors, don't worry as they still function well. Just be gentle when installing phoenix connectors. For maintenance, keep the unit in a dry and clean environment. Regularly check the connections to ensure they are secure. If you encounter any performance issues, first check the power supply and all the connections.
