Well,
them chinese transformers are certainly not what i am after - especially - when DIing signals with lots of bass, LOL.
These tiny things are so smallish....and suck out all bass power...
But if i would want that - i certainly would try a Beyer transformer for this task, LOL.

But if i would want that - i certainly would try a Beyer transformer for this task, LOL. They suck out the low end, sure. But you can get some nice 2nd and odd order distortion on the lower order partials. With a little low shelving post DI you get both. I mostly do it on flats. |

cant boost whats not there? They don't disappear low frequencies, it's just that smaller transformers limit peak power output. Low frequencies essentially have a lower clipping threshold than higher frequencies because low frequencies make up the majority of the power in an audio signal. As you jack up the signal the low frequencies "Clip" but the rest don't, meaning that it does act as a sort of high pass filter. But it depends on your gain staging and you can compensate for that with a really low Q shelf. |

Yepp jazznoise,
that's the way it is.
E.g. the Bo DI that i built acts a little bit like a hipass filter, but in a pleasant way sonically. The better/"cleaner" way esp. for Bass DI would have been taking the Lundahl LL1538XL instead of the LL1538 because it maintains more bass power...
SOME smaller and cheapish transformers actually *can* work in special applications, very well.
E.g. the LA-4 can take even the smallish TM019 transformers (around 3 bucks at Banzaielectronics or at Musikding) for output astonishingly well with no problem. At least in the DIY version of Luny Tunes. But it is as close as it can get to the real thing, so i think it might work in the original units also. So it is not *generally* like the small transformers always act as an undesired type of hipass filter. That's certainly true...
Best regards,
Martin

Best regards, Martin Nicely made point, the "size" of a transformer and its importance varies depending on application, voltage and impedance. Another obvious problem for some cheap transformers is that implementing a Zobel network to dampen any ringing can have limited effectiveness if poor design is the root problem. A key point I implied, but omitted, in my last post was that the additional power over the threshold for the given sinusoid becomes the harmonic distortion. Assuming you EQ to compensate for low end loss this makes it a low-mid/midrange thing and it can make things pretty forward sounding - I like it on my flats on my cheap Harley Benton, but IMO it doesn't really work on a J Bass. |

I've been eyeing the Palmer boxes the last few days. I want one. I know I have a Kemper but I'm all about possibilities.

Well, maybe it helps you on your decisions--- This is the heart of Palmer boxes. Well. I do not want to judge. I never had one in hand, but BSS ones. and well, i wasn't too impressed by them too, they do their job OK...and i guess the Palmers can be considered more or less the same range... Well, in my opinion, these kind of DIs are just ONE step up from the 10$ no-name DI, and i guess you pay half of your money for the fact that it is a trademark and *not no-name*. OK - YMMV, very subjective personal opinion.  Best regards, Martin |

Actually a funny sidenote...
i do have two of those big chinese B. DI-boxes from "Uli". A blatant BSS ripoff including the design...át lower price point of course.
In the meantime he bought BSS. LOL.
Well, they are a ripoff? No problem anymore, i bought the original.
Brilliant. Kind of.

yes, and this is the one you need, use the haufe tranny, it sounds so good you'll laugh, there have been many who've owned some really pricey DI's, that never usem anymore after Bo Hansen showed up. easiest build in history, sounds extra amazingly good on bass T heres my stereo rig thanks for the inspiration, I'm going to go with the Haufes from Volker on my builds also |
