Yes. When the mode switch is set to "A+B MIX ↔ BYPASS," the signals fed to RETURN jack A and RETURN jack B are mixed and output from the OUTPUT jack.
The volume for each signal fed into RETURN jack A and RETURN jack B can be adjusted independently with level knobs A and B, respectively.
Note:
- When using this connection method, a dummy plug must be inserted into the INPUT jack to turn on the power of the LS-2.
- A guitar can be connected directly to RETURN jacks A and B.
- This connection method is not well suited for mixing low-level signals, such as microphones. It is best used for guitar or line-level outputs.
