INV 2488 The Rolls MX41 is a passive mono 4-channel mixer. It is small, less than the size of a standard guitar pedal, and it has 4 passive volume controls for the 4 inputs, and a single output. All of the connections are 1/4 inch. It feels and looks very solid, just like all Rolls products. When all the knobs are turned up, it can also be used backwards as a signal splitter.
