[SlimDevices: Audiophiles] Please help me understand attenuation issues
I read the wiki articles on connecting to a poweramp from a squeezebox and I am confused. I don't have any knowledge of electricity or electronics. I am worried about the attenuation issues. I plan to buy a pair of QSC HPR153i 15 3-way Powered Loudspeakers. Why do I want these mammoth beasts for my modest home? Well I also play the guitar through a Line6 Pod (a guitar amp modeler), which is a live sound application, in addition to my squeezebox which is a prerecorded sound application. Both of these sound sources offer line level outputs. I may connect them both to the speakers via my Mackie UNpowered mixer (1202 VLZ). My question: Can a kind reader please read the specs for the speakers (they are available on the QSC website) and tell me what issues I should be aware of in this proposed system.

Thanks The Mackie is your preamp in this scenario and will be perfect for performing all your attenuation duties. If you intend to control the volume of the squeezebox with the squeezebox remote then you'll want to set your levels by doing the following: 1) Run the squeezebox at full volume 2) Adjust the gain/trim knob on the input you're using on the mackie to a bit below clipping (leave some headroom here as some songs will inevitably be louder than others) 3) Crank the fader on that channel of the mackie up until the volume level is a bit louder than you imagine yourself ever wanting to listen 4) Turn the volume on the squeezebox down to a comfortable level. You can now use the squeezebox's volume control safely and get the best use of its volume range. Don't change any of the settings for that channel on the mackie. If you intend to control the volume of the squeezebox from the Mackie board you'll still do steps 1-3 from above but then you'll leave the volume of the squeezebox itself at 100% and just regulate the volume from the Mackie fader for that channel. -- azinck3 azinck3's Profile: http://forums.slimdevices.com/member.php?userid=3967 View this thread: http://forums.slimdevices.com/showthread.php?t=34260 ___ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles

Thanks for the help. I have a follow up question. The QSC's have gain controls as well. Should the QSC gain controls be set in any specific way. And the fact that the QSC's have gain controls mean they have built in preamps? -- mortslim mortslim's Profile: http://forums.slimdevices.com/member.php?userid=11039 View this thread: http://forums.slimdevices.com/showthread.php?t=34260 ___ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles

Your best bet will generally be to run the gain at unity and just accept whatever level the Mackie outputs. -- azinck3 azinck3's Profile: http://forums.slimdevices.com/member.php?userid=3967 View this thread: http://forums.slimdevices.com/showthread.php?t=34260 ___ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles
