I'm looking for a selector switch to allow three inputs to a preamp, I think I saw that you had one on an Opus Dac build that you posted a while back. If my memory is correct could you tell me where you got it from ?

Hi Paul-

In the DAC I used one of the 3-position/4-pole rotary switches from our Darwin kits to control an OTTO prototype, resulting in a two-source selector + off. I did not run any analog of digital audio signals through the switch. I simply ran Vbus from the USB module (5V when USB connected) to the switch, then to the OTTO. I also ran AC power to one of the switch poles. In the Off position, everything was disconnected. In S/PDIF and USB positions, the system was powered up. Since the OTTO was being powered by Vbus, if no USB source was connected, the OTTO coudl not turn on, so S/PDIF was always active, regardless of whether the selector was set for USB or S/PDIF. Once Vbus was available (there was a USB source), selecting USB would enable the USB via the OTTO. I also used small bi-color LEDs, switching them with yet another switch pole, to indicate which sources were available.

Hope this helps.

The rotary switch is from Mouser, part number 105-SR2511F-43FN.
