[QUOTE="Taipan, post: 22042, member: 11681"] Hi Mark, That's exactly my sentiments, too! - which is why I have built all the electronics into the sub-woofer box, so my entire hi-fi system/media centre is just a small case containing the PC and MediaPortal, a DLP projector and the 5.1 loudspeakers. And it is all controlled by one remote control - a MCE remote. Its all DIY, including the speakers. The current power-amplifiers are my own 50W discrete design, and there are a total of 9 power amplifiers. There are 2 amps powering the sub-woofer (with an active cross-over that splits the signal to the sub-woofer), 2 amps powering each front satellite (which each have an active cross-over to split the signal between mid-bass and tweeter), and 1 amp for each of the centre, left-rear and right-rear speakers. I have a little module containg a PIC microprocessor that receives the RS232 signal from the PC to turn the power-amps on and off, and to control the mute on the power-amps. This module is also built into the sub-woofer box, but is separately powered so that it is always on (so it can constantly monitor the RS232 lines). I use the PC's sound card to decode the digital sound (stereo, AC3, DTS etc) and feed the analogue outputs directly to the power-amps. Apart from the active cross-overs, there is no pre-amplifier or any other knobs and whistles! All the control of the sound is done from within MediaPortal and Windows. I use [url=http://www.byremote.com.au/downloads/default.asp?SCLASS=UTILITIES]COM Controller[/url] to output the appropriate RS232 commands from the PC, and the COM Controller command-line script is executed by PVR Scheduler after a "Resume" or before a "Standby". At the moment, if the PC is resumed for a scheduled recording, or to grab the EPG, the power-amps come on too - which is unnecessary - but STSC (the author of PVR Scheduler) is going to add an option to disable the scripts when the PC is resumed by a Scheduled Event. My next challenge is to also control the DLP projector from the PC, and I am upgrading the discrete power-amps to a new (more compact) design based on the National Semiconductor's LM4780 & LM3886 power amplifier ICs. I am happy to share as much detail as you require, but being DIY, there is not much that I have documented! PM me if you would like more specific info.... :) [/QUOTE]
