I recently had an issue with my media center; the 90s AIWA stereo I used only offered two RCA inputs and I needed four. Sure, it’s probably time to upgrade to something more recent with more inputs, but I couldn’t justify buying a whole new receiver when I’m about to move out anyway. Instead, I decided to build an RCA switch box.
The design of the switch box was simple enough. It consists of a three pole, four position rotary switch and 5 pairs of RCA jacks wired accordingly. The jacks and switch were ordered from DIGIKEY, while the enclosure and knob came from Radioshack. For wiring, I salvaged the inner wires of a broken MONOPRICE TRS audio cable. The color coding proved useful in discerning left from right channels.
- Four inputs for one
- Complete control over quality
- Looks awesome
- No audible crosstalk
- Ground didn’t need to be switched. I could have used a two pole five or six position switch instead, giving me even more inputs.
- The cables tip the box backward unless there is a weight on top of it.
- Have to get up to switch sources
- Much more expensive than cheapo made in China switches
- Heck yes.
