Infinity PS-12 Subwoofer clicking in and out of standby

I have an Infinity PS12 Subwoofer that is clicking in and out of standby after it warms up. I am running it in the inputs that take the line-level inputs and have the LFE turned about half-way up. Any ideas of what I could check?

    I have a similar problem. The sound coming from my PS-12 is very quiet during movies or TV. It actually seems to work right away and fade quickly. I too have mine hooked up into the LFE port. When I run a "test tone" from my receiver each speaker outputs white noise, along with the sub. (although it is much lower and quieter, but I assume that is typical)



    My PS-12 also "chirps" at me occasionally. It seems to happen when it recognizes audio input. Normal? I may have to call Infinity.

    I have the problem exactly as stated, after it warms up it clicks on and off, forgot where I bought on line, looking for someone to repair.

    I have the same problem, the speaker is clicking on and off and nothing appears to rectify (unplug, cycle power switch, clean terminals, let it cool down). I bought the sub from ultimate electronics without extended warranty and don't know who to take it to for diagnosis. Sad thing is the unit is only about a year and a half old.

Hello,
Unfortunately your subwoofers amplifier circuitry will need to be repaired ,the amplifier is bad and kicking in to protect mode. This mode is designed for safety of the unit and user and sub should not be operated until repaired as it may incur more damage to the components. I hope this helps.

    This is a common problem with the power supply and the unit IS NOT going into protect mode.

  • Steve Jul 12, 2012

    No, the unit is not entering "protect mode". There is a known problem with the power supply overheating and capacitor(s) burning.

I've got the same problem with my PS-10 from Infinity. It works great for about 30-45 minutes, then click in and out of standby mode. It sounds to me like a overheating safety fault. When I take off the amp panel (unplugged), it feels quite warm, and you can see that there is really no way for heat the escape. I tried running it briefly with the amp panel outside and it seemed to work fine! Since I'm out of warranty, I think I'll try cutting some ventilation holes. I noted there are 2 oval shaped holes near the bottom (just above amp), but covered with the panel sticker. I'll try cutting those open first.

Same problem-I had my PS-12 repaired about 1 year ago under warranty. Problem was identified as- repaired power supply by replacing two capacitors. There was sign of circuit overheating. Problem has reoccured. Looking for larger voltage capacitors to R/R. My assumption, great speaker but bad design by Infinity. I need schamatic to have better idea for repairs, could be something else burning the caps. Any ideas!

    I have cut-out the label over the two holes and glued some thin foam rubber over them to keep the dust out. I also drilled some 1/4 inch holes along the edge and top of the plastic cover. This helped cool the power supply and after I replaced a burned capacitor, it worked for a while longer but I think there may be a weak transistor the drops out when hot.

How do i fix my infinity entra 10 inch 150 watt powered subwoofer. fuse is good, green led is on so it is getting power


Best to start at the beginning. You have it connected properly? Are you using the line level, direct or speaker inputs? What output on your receiver are you using?
Have you adjusted the volume control?
If you have everything correct, are you the original owner? It's an older model so if you are the original owner what happened when it stopped working? Noises, fade out, just wouldn't turn on one day.

Are you capable of doing some minor electrical work? Can you read a schematic? Can you recognise electrical parts? If the answer to any of these last three questions is no, you need to take it to someone that has the ability to do electrical repairs. If the answer to all three is yes you can fix this yourself.

Need help connecting Velodyne VAX Series (1995) to new Denon AVR X2000


If your subwoofer has a line level input (RCA-style plug), see page 24 of this link: http://www.audioproducts.com.au/downloadcenter/products/Denon/AVRX2000BK/Manuals/AVRX2000E2_ENG_CD-ROM_IM_v00.pdf

Run a cable from that to the line level input on the subwoofer. If I understood you correctly, here's a link to the owner's manual: http://velodyne.com/vx-11.html

Apart from the "line input"


input and output are for low level ( as with RCA cable connectors) ,, the speaker connections are for high input, (red and black connections. ) you can run the mains to the (rca) from your receiver to run the sub woofers, and from that use the speaker wire connections, to go to the left right speakers, (out only not in) this is done if you want to run the subs and the Rt/lt/ speakers , eliminating the speaker connections coming from the receiver. which you could use for 2 additional speakers if you want

How do u hook up the infinity entra sub it has speaker level(input and output) that look like these red and black spots r for spearker wires and then line level input so I connect my music to the rca plugs...


Maybe if you described the setup with exact model numbers for everything involved we might be able to answer with specifics.

You could poke around her for the Entra Manual for YOUR model.

http://manuals.harman.com/INF/Hom/Owner's%20Manual/

What they do NOT explicitly tell you is that the amp in the sub is not for your other speakers running off it's Speaker Level outputs. They're just there as a pass-through if you use Speaker Level from your own amp.

Line Level (RCA) IN to the sub will NOT pass anything out those Speaker level outputs.

Is it possible to hook the infinity bu-1 subwoofer to a home theater system where the subwoofer output is straight power say it"s like 25 watts coming out of that one channel and before the original...


In general higher speaker impedance is safer than lower impedance for the amp. Don't expect anything impressive re: audio output from a passive (unpowered) sub if your HTS says it pushes only 25 watts. Without frequency bandwidth and distortion noted the spec is virtually useless as a comparison.

The BU-1 is a powered sub that accepts either RCA Line Level or HIGH LEVEL amplifier power. If you use the latter, impedance is a non-issue because the input feeds the BU-1's internal amp, not the speaker directly. You should be okay.

Perhaps if we knew some specifics about the HTS we could do more than guess.

Which is the best way to hook up a Subwoofer?


Last two questions first - YES, use an RCA splitter to share sub line level out between two subs and use one at the subwoofer end to share that line with both inputs on the sub.

Either attachment scheme you describe would work.

Not being a big fan of conversion/deconversion for no real purpose, I would avoid stepping the high-level input down to line level for use by the sub's internal amp, run RCA to the sub(s) and keep them physically and electrically independent of anything else unless cable routing is facilitated somehow by daisy-chaining other speakers from the sub(s).

Connect powered subwoofer


  • If your receiver has a dedicated subwoofer line level output, we recommend connecting your subwoofer to this jack. Most receivers will have just one (mono) subwoofer output, while quite a few subs require two inputs. You can use an RCA "Y" adapter cord , which is a cable with one female RCA jack at one end, and two male RCA plugs at the other. Some receivers require menu settings (such as "sub-on" or "front speakers-small") that must be made before the sub output will be active.

    Have an existing ts-1100 home theatre infinity speakers


    You cannot use this system with one that does not have a Subwoofer or LFE (Low Frequency Effect) output. Unfortunately, this sub doesn't have a line-level (speaker wire) input. Sorry.
