Found this switch in my cab today


New member
So I’ve found a switch in my 8ohm Carvin cab and wanted to try it out. It has a switch for Mono 8ohm, and Stereo 4ohm/4ohm. The cab itself has an input for left/mono, and a second one for right/extension. The amp I have has 2 parallel outputs, and can switch between 4/8/16 ohms.

The cab is switched to 4ohm/4ohm stereo, the 2 amp outputs are connected to both left and right inputs for the cab, while the amp is switched to 4ohm impedance.

The question is, am I plugging it in correctly with the correct impedance? I’m trying to use both loudspeaker outputs and the cab stereo inputs

The photos are for reference, taken at different times, and do not depict actual setting. Currently, the amp has 2 outputs connected to the 2 cab inputs at 4ohms and 4/4 stereo respectively.
