3. Connect Audio Destinations: Connect the Stereo Outputs (A, B, C, D - L/R RCA) on the rear panel of the LS-4 to your desired audio destinations (e.g., studio monitors, headphone amplifiers, effects processors).
4. Power On Equipment: Once all connections are secure, power on your audio equipment, starting with the source and ending with your amplifiers or active monitors.

6. Operation

The Black Lion Audio LS-4 is straightforward to operate:

• Single Output Selection: To send your stereo audio source to a single destination, press the corresponding channel select button (A, B, C, or D) on the front panel. Ensure only one button is engaged.

In this configuration, connect your four stereo sources to outputs A, B, C, D, and connect the main input to your desired destination. Then, press the corresponding button to select the active input.
