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. <br /><br />Hope this helps.<br /><br />The rotary switch is from Mouser, part number 105-SR2511F-43FN.<br /><br /><img src="http://www.twistedpearaudio.com/user_gallery/_burning_dac/DSCN8942.JPG" alt="UserPostedImage" class="UserPostedImage" style="max-width:200px;max-height:200px" /></td></tr></table>2008-05-11T05:36:13-07:002008-05-11T05:36:13-07:00Brian Donegan<table class="content postContainer_Alt" width="100%"><tr><td>Hi Paul-<br /><br />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.
