  1. Art cleanbox for turntable.

    Two Channel Audio
    Hi guy's. I have a Kenwood KD-550 TT and it doesn't have the output that the Project debut carbon that I sold to get the 550 had. I have to turn up the attenuation on my pre amp quite a bit more to get the same volume as I was getting with the PDC. I know this happens allot but I was wondering...

  3. ART Cleanbox Pro Set-up

    Electronic Processing/Equalization Devices
    My search fu skills are not what they used to be. I am looking for instructions on how to best set-up a ART cleanbox pro. I am running a Yammy AVR into a QSC RMX 2450. Of course, the Yammy does not have the power to drive the pro-amp, so I added a ART CBP to the mix. Thanks in advance.
  4. ART cleanbox pro question

    Subwoofer Amps | High Pass Filters
    I have had other direct boxes and its always pretty straight forward. But I am trying to primarily use the box for unbalanced to unbalanced gain only. And to clean up alittle static noise out of my 1/8" out on my IMac to the amps powering my L/R and sub. Seems to me that the box is intended...
  5. Anyone experienced with the ART cleanbox pro ?

    DIY Subwoofers - General Discussion
    I just hooked up this unit to a new Behringer EP4000 and somethings amiss. I cannot turn the cleanbox's gain controls up beyond about 5% of the dials travel without hum and buzzing through both channels. If I stop just short of the interference point, I then have to turn up my processor sub gain...
  6. Cleanbox picking up radio stations?

    Subwoofer Amps | High Pass Filters
    I have had my cleanbox for about 9 months or so and recently I have been having an issue with it picking up an AM radio station (1510 to be exact). When I first got it I did the capacitor mod and haven't had any problems up to this point. I have checked my solder joints and they are good...
  7. Have ART Cleanbox, looking for better route...

    DIY Subwoofers - General Discussion
    One year ago, [I] purchased a QSC RMX 2450 pro amp. I used a RCA TO QUARTER INCH JACK with lack of full power. Then after reading a few threads on this site, decided to get an ART Clean box. Currently I have been thinking about upgrading this device. Was thinking if a mixing board would work if...
  8. Art Cleanbox Question

    AV Home Theater
    I decided to retry using the cleanbox (it started tuning in radio broadcasts last time I used it). This time, I ran the xlr out channel 1 on the cleanbox into the xlr back in on channel 2 on the cleanbox and then used rca to 1/4 for the pro amp. This seems noise free and it definitely gives me...

  10. ART Cleanbox DC power supply

    AV Home Theater
    What are the power supply requirements for the "wallwart" that comes with the cleanbox? I got a cleanbox for a few bucks used and it is missing the dc powersupply. All I know is that it is 12 volt.

  12. Cleanbox or Cleanbox II?

    DIY Subwoofers - General Discussion
    Does it matter which one I buy? I'm looking for something to clean the hum between a commercial a/v receiver and pro-amp, as well as boost the signal. I've got the majority of my hum removed by using cheater plugs and ground cable from chassis to chassis. Can't seem to get rid of that last...

  14. Cleanbox mod question

    DIY Subwoofers - General Discussion
    I just got back form my local electronic component store and picked up some new caps for my cleanbox. I bought two types because I forgot which ones are better. The first is a 63V 1uF Metal Polyester Box Capacitor that was 3 bucks for 2. The second is a 50V 1uF Ceramic Cap that was 5 bucks...
  15. Will BFD increase input sensitivty similar to what a CleanBox does?

    Electronic Processing/Equalization Devices
    I just finished my 14 cu foot IXL18.4 LLT sub tuned to 14hz. I am currently powering it with a Behringer EP2500 lead from a Panasonic XR-55 receiver. I am connecting my receiver to the EP2500 using the sub out (RCA) from my XR-55 into a 1/4 TS adapter into the EP2500. It's pretty apparent...

  17. Art Cleanbox or what else?

    DIY Subwoofers - General Discussion
    well as i thought, im not getting enough to the amp to have the sub keep up with the mains, and i know the cleanbox has a roll off, and i also saw the mods to it is there another device that will do the same thing? for cheap too i also had to buy a ground loop isolator, if i get a clean box or...

    EDIT I re-did the measurements, and found them to be quite flat. See this post http://www.hometheatershack.com/forums/bfd-forum/6228-art-cleanbox-ii-fr.html#post49929 Thanks Jim Hello all, been too long. I've seen the Cleanbox threads, but I haven't seen anything for the CleanBox II, ao I...
  19. ART Cleanbox mod thread

    DIY Subwoofers - General Discussion
    I am always interested in moding devices to improve their performance. and with the release of the info that the Cleanbox is really killing the low end I think that we all need to pool our knowledge to mod them to improve where it is lacking. I personally have no real technical knowledge of...
  20. ART Cleanbox frequency response

    Subwoofer Amps | High Pass Filters
    Since the ART Cleanbox is often recommended to those having low signal level problems with their pro amps, I thought to try it out. For my disappointment, it turned out to be less than adequate for my needs. Here's its frequency response (measuring system is flat). As you can see, its FR...
