Hi Greg, First of all my disclaimer ! You do any of this totally at your own risk a good knoledge of mains wiring practices and high voltage workings is nessesary for your own safety. If you do not posess these skills do not try any of this. Modifying your Hifiberry DAC+ like this will obviously void the warranty. Having said that... :) I have 3 systems that power on their poweramps via signals from the "squeeze player" 1. Bathroom. Squeezebox Classic to HifiMediy T2 (with analogue PSU (300VA Toroid)) 2. Bedroom. RPi2 running piCorePlayer with HifiBerry DAC+ to HifiMediy T2 (with SMPS300 PSU) all in one case 3. Lounge. RPi2 running piCorePlayer with HifiBerry DAC+ to HifiMediy T2 (with SMPS300 PSU) all in one case System 1 uses a LMS plugin called Powerswitch III to enable an SSR via the headphone output. http://www.gwendesign.com/slimserver/dev_hard_and_software.htm#powerswitchii http://forums.slimdevices.com/showthread.php?92432-Squeezebox-Touch-and-Power-Switch-II Systems 2 and 3 use a modified Hifiberry DAC+ to enable the SSR The DAC+ has an LED (D1) to indicate that the output is active I user 1/0.4 wire soldered into the vias circled in RED these two wire then go to the SSR 18988 The picture below shows the SSR's I have used, on the left is a Crydom 25A SSR these are around £40 each and rather OTT for this job. I only used the Crydoms as I had them to hand in my workplace, in unit 1 this have run fine for around 10 years. On the right is (almost certainly a fake) FOTEK 25A SSR these are £2-£3 on fleabay these have worked fine on units 2 and 3 for many months now. 18987 See this though http://www.instructables.com/id/The-inner-workings-of-Counterfeit-FOTEK-SSRs/ Sorry but as for the volume controls etc I use apps and PC to control mine so cant really help It might be possible to power a signal switching relay with the power control (with suitable isolation of course) +-------------------------------------------------------------------+ |Filename: HifiBerryDac+ModSmall.jpg | |Download: http://forums.slimdevices.com/attachment.php?attachmentid=18988| +-------------------------------------------------------------------+ *Players:* SliMP3, Squeezebox 3 x 3, Squeezebox Receiver, SqueezePlayer, PiCorePlayer on RPi 2 with Hifiberry DAC+ x 2 *Server:* Logitech Media Server Version: 7.9.0 - 1443766458 on Centos 7 VM *Plugins:* AutoRescan / BBCiPlayer / PlayHLS / PowerSave / PowerSwitchIII *Remotes:* iPeng8 / Orangesqueeze / PC *Music:* 383GB, 1269 albums with 17756 songs by 4381 artists mostly FLACs / Last FM / Soundcloud *Want a webapp ?* See http://forums.slimdevices.com/showthread.php?104305-Webapp-for-LMS ------------------------------------------------------------------------ Jeff07971's Profile: http://forums.slimdevices.com/member.php?userid=49290 View this thread: http://forums.slimdevices.com/showthread.php?t=104084
