    It's a horrid, quite loud scratchy noise too. Can't be much good for the ears.

    Solderdude meant it to be more like a bass 'honing' facility. Some headphones react more to it than others.

    120 ohms output impedance used to be the norm years back but modern designs tend to get as close to zero as possible.

    I think you are right. Instead of just believing an 8x theory, it is in fact better to let your ears judge. If it sounds good, then that's fine.

    Wow, that has to be the very original Ember.
  4. HOWIE13
    It probably was- I'm very old too [​IMG]
  5. RedBull
    I also not young :D

    My Ember is about 2 years old (pretty sure its the original) but it has the caps by-pass and input gain jumpers.  Had to install supercharger later
  7. HOWIE13
    yes mine has caps bypass but it's on the input not output, and at the back it appears to be an 'attenuation' jumper rather than a 'gain' jumper.
    So it doesn't increase the gain if the signal is low, it lowers the signal if the input is high so as to afford more use of the vol pot. At least that's always been my understanding.

    Mine 'gain' setting is also jumper. I always have enough gain with jumper in low setting. If the input is low, I use High gain.
    That's my understanding.
    Or maybe we talk about the same thing but different perspective? :D
  9. HOWIE13
    Yes we are saying the same thing really. I'm a bit drugged up with pain killers for a twisted back just now so apologies if I'm not thinking straight.
    At least my hearing is not affected. [​IMG]

    Sorry to hear that mate, I genuinely feel your pain having been there more than once. Top Tip - get your Doc to prescribe Tramadol & your hearing will astonish you. :wink:

    Don't rush back to athletics!!!
  12. HOWIE13
    Thanks, Gordon. Actually I tried Tramadol and I felt really weird but they did work for a short period.[​IMG]
  13. HOWIE13
    I'll wait a few weeks Ian.

    An inquiry would be preferred over an assumption filled rant.

    Or alternatively, take the headphones off for a second while changing the jumper. :)
