    Hi Karl

    What you are describing is not normal nor what is expected of the PULSE. It is likely defective. You mentioned you purchased it second hand so as a result you likely are not eligible for any warranty or after warranty options. Please check out www.bluesound.com/stored and click the link to view Distributors. Depending on your country, some of our regional distributors (but not all) may offer repair options. The PULSE however, being an all in one product is sealed so any possible repairs may not be worth it compared to re-purchasing.

    I am sorry to hear about your predicament but this could be an example of why it may be best to stick to an authorised re-seller.

    Thank you for replying.
    My hope here was to glean some actual information about the product and how the amplifier topography is arranged. My hope was that something might be done to reduce the noise, either by filtering the power input in some way or by a software fix.

    Bluesound products has a good reputation in Sweden where I am located and I would expect the components in them to last longer than five years, at the price point they are at. In my opinion, a good quality product should be able to handle a couple of owners and getting good quality products second hand is usually a very good option resource wise, for both consumer and from a waste standpoint. I find that most companies that do sincerely back up their products will still be helpful when issues arise, even if they have been re-sold. I had hopes of this applying to Bluesound as well, but after reading several tales of tech support interactions I'm starting to get the impression that that will not be the case.

    Karl, in case you still own the hissing Pulse 2. I had the same experience with two pulse 2 speakers. One died and was replaced under warranty by a Pulse 2i (HiFiKlubben service), and the other one died a couple of weeks ago.

    I decide to take it apart and inspect the boards, especially the capacitors. Only poor unknown quality caps are used, some even rated 85 degrees. The KSC 1000uF 35V caps on the amp board were bulged.

    I recapped both amp board and power board with Panasonic and Nichicon caps of the same values. Quite straightforward if you have some experience in soldering (and have access to a desolder station).

    After recap the sound is crisp as new and the hissing is completely gone. Dead silent. So the design is good, the components are bad. No pulse 2 speaker will last 5 years “always on” without a recap.

    So if you or anybody else has a dead Pulse 2 (solid RED led), recapping it turns it as new. Also improving sound quality a lot, bulging caps on the amp board and out of spec PSU is not helping sound quality.

    My two cents!
