Yes you can, but the gain staging might be sub-optimal. If when you connect it up like this you find that at 100% volume setting on the TP it's louder than you'd ever want, you should add some passive attenuation. Have a look at these wiki pages: http://wiki.slimdevices.com/index.php/Connect_To_PowerAmp http://wiki.slimdevices.com/index.php/BalancedPowerAmps http://wiki.slimdevices.com/index.php/DIYPassiveAttenuation Ozz;442251 Wrote: > Next question: are the IR connections just 12V trigger for the amps? No. In their "native form" they send and receive IR codes to/from other equipment (with assistance from the IR Blaster plugin). If you want to get some kind of trigger signal to switch the power amps on/off with the TP, they can easily be arranged that way, using Felix's PowerSwitchII plugin (http://www.gwendesign.com/slimserver/dev_hard_and_software.htm#powerswitchii). What you get out of the IR socket using this plugin is a DC signal of about 3.2V, not 12V. If your amps have a 12V trigger input, then you can step it up using a transistor as described on Felix's page. Note that this requires an external power supply. However, what you say next changes things slightly...

Passive ATCs? - you heretic! :-) If you plan to get active ATCs, then (unless ATC have recently added a DC triggering facility), you'll need to switch the mains power. The most elegant way to do this is to use an opto-isolated triac (eg. MOC3020 or similar) switching a power relay with a mains voltage AC coil. This requires no external power supply (the mains power you're switching is itself the power for the relay coil). You'll need to add a resistor (about 75 ohms) to step the 3.2V down to about 1.2V, which is the voltage needed to switch the opto-triac. (This same arrangement can of course be used to switch the mains power to your Arcam monoblocks in the meantime). -- cliveb Transporter -> ATC SCM100A ------------------------------------------------------------------------ cliveb's Profile: http://forums.slimdevices.com/member.php?userid=348 View this thread: http://forums.slimdevices.com/showthread.php?t=64028 _______________________________________________ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/audiophiles
