Item# DSA-LSP-3
The D San LSP-3 is a passive direct box; you may think of it as an "extension cord" for your crowded audio mixer. It provides 1/8" and 1/4" stereo TRS jacks to accept headphone-level computer or instrument audio with loop out RCA phono; 1/4" TRS mono jacks to accept low-level signals from instruments or media players; and an 1/8" stereo plug to capture headphone audio from computers, cell phones or media players.
There is volume control, and a selector switch for L, R or L+R combined...
