Setup
The UNSTINCER RCA L/R Audio Switch supports two primary configurations: 1-Input-2-Output and 2-Input-1-Output. Ensure all devices are powered off before making connections.
1. 1-Input-2-Output Configuration:
This setup allows one audio source to be routed to two different output devices (e.g., a computer to speakers and headphones).
- Connect your audio source (e.g., PC, Blu-ray player) to the "IN/OUT" RCA ports on the front of the switch.
- Connect your first output device (e.g., speakers) to the "IN/OUT 1" RCA ports on the rear of the switch.
- Connect your second output device (e.g., headphones) to the "IN/OUT 2" RCA ports on the rear of the switch.
- Use the "1/2" selector button to choose between output 1 or output 2.
2. 2-Input-1-Output Configuration:
This setup allows two audio sources to be routed to one output device (e.g., a phone and a computer to a single set of speakers).
- Connect your first audio source (e.g., MP3 player) to the "IN/OUT 1" RCA ports on the rear of the switch.
- Connect your second audio source (e.g., Smart Phone) to the "IN/OUT 2" RCA ports on the rear of the switch.
- Connect your output device (e.g., speakers, headphones) to the "IN/OUT" RCA ports on the front of the switch.
- Use the "1/2" selector button to choose between input 1 or input 2.
