  1. AC Infinity Coolers

    Home Theater Receivers | Processors | Amps
    Have an older set of Parasound HCA 1500A amplifiers which were getting uber hot with the Wisdom Audio Ribbon Speakers. Just installed these T-8 coolers from AC Infinity and amps stay cold now regardless of volume. Just thought I'd share.
  2. XLS2500 - Power output vs AC consumption

    Subwoofer Amps | High Pass Filters
    Hi guys. I need an ELI5! How does a power amplifier that is capable of an output of 2400W RMS, only consume (from the print at the rear of the amp) 425W? I'm going to assume Crown have not invented a free power device - what gives? I understand that a switch mode D class can be efficient; but...
  3. AC Power Conditioning Clarity

    DIY Audio
    Right now I have two interests: Balanced Power and Power Conditioning. I've seen tons of posts all over. Even on other forums. What I'd like to do is get some input on starting a DIY project. I understand that not many would want to post build information due to the dangers. However, advice and...
  4. My life's project to build an AC Cobra.

    Chat Box SWAMP
    Thought show some pictures of the project that has been a part of my life, because I celebrate 20 years of construction this fall. I know! It is not wise but construction has been a hobby ... With time there ... Money ... And desire ... it is not always the most parameters in stroke. New...
  5. DIY Balanced AC Power

    DIY Audio
    I could not help but notice a lack of discussion about power conditioning projects on HTS. Over the years I have tried various audiophile power conditioning devices with varying degrees of success, until coming across balanced AC power. Since 2004, when I tried my first DIY balanced AC power...

  7. AC turn on device

    Remotes | Cables | Accessories | Tweaks
    Hi all, I'm looking for an AC outlet/power bar that can be turned on via 12volt trigger or an IR remote. I currently have a Dayton 1000 watt plate amp for my subwoofers. I would normally use the auto turn on function, but the idle current when the amp is on standbye is quite high (24watts). Is...
  8. Balanced Power? Online UPS? Dedicated AC?

    Pro Audio
    I have my home studio in a 50-year-old apartment which has only 2 prong outlets that really drives me nuts ... and it hums or buzzes like crazy too.. I already have an isolation transformer but it does little for me... recordings still sound flat with floppy low end and weak attack, really...
  9. AC hum on Subwoofer

    System Setup and Connection
    Hi all, I'm having problems with a kit subwoofer. I was able to play it last year after some initial problems with humming (which were never properly diagnosed but somehow went away after enough fiddling), but took it apart to apply veneer. Now I've reassembled it but as soon as I turned it it...
  10. AC Cord UPgrade = Peace of mind

    Remotes | Cables | Accessories | Tweaks
    My new PIONEER SC35 came with an AC cord SOOO cheap I seriously would'nt plug it in until I got this PANGEA AC9 upgrade. Call me paranoid but I now have the peace of mind knowing that my $800 AVR wont be compromised by a $1 AC cord :) After a week of break-in I did some A/B comparisons and I...
  11. Samson S Convert 220v AC adapter needed

    DIY Subwoofers - General Discussion
    Hello, I live in Israel and since the S-Convert isn't sold here (no demand) I got my mother to buy it for me in the US. only problem is that the us version comes with a 110v AC adapter and I need the 220v version - so I went to the samson dealer who sells other samson "S" products which use the...
  12. 12V Trigger AC Outlet

    Home Theater Receivers | Processors | Amps
    I'm sure there are others who are dealing with the same issue. But I didn't want the EP2500 and DCX2496 on all the time. They don't have triggers on them, so there's no simple way to just make them turn on and off with your receiver or processor. But if you're like me and don't want them to be...
  13. DIY AC cords... NO FLAMES, just curious......

    Remotes | Cables | Accessories | Tweaks
    I have recently pulled 4 each 20 amp 120 VAC dedicated circuits in for my system (using 10 gauge home runs). 2 of my amplifiers come with 20 amp power cords and the owners manual recommends a 20 amp circuit per amplifier. After doing some reading and talking to one friend in particular (whose...
