1. Ask the tech stores for a mini jack (3.5mm) — 2x 1/4″ (stereo) jack cable.
Plug the mini jack into your laptop (or other audio device) headphone out.
Plug the 2 jack connectors into SPL IN Left and SPL IN Right on the patchbay.
Note: If you are wanting to represent your audio in stereo, ensure you connect to the SPL jack ports correctly. Remember white is left and red is right.
SPL Monitor Controller Setup:
2. Press the Surround Stereo button in.
3. Turn up the volume on the SPL monitor controller.
You will now hear audio coming through if it’s playing.
