Thanks for the kind words zilch.

I looked at the math features.  Comes standard with FFT!  Sweet!

 

 

@Gary in MD Lol, I don't like to watch TV either :P

@robrobThe hack is still doable yes, you just need to do a different method than before :) 

@potterma Yes, it comes with a lot of useful extra features, not to mention being able to store data, and present info online! 100mhz hack is icing on the cake too.

Always ready to help and such a geek!  What's not to like about you, Brunk?  

 

(Don't tell us - I'd rather not know!)

 

:beerchug:

Lol, I am definitely a geek at heart :tongue:

Brunk, do you have a link to the new hack? My wife would kill me but I might have to get this scope.

Look at the last few pages of this thread :)

Thanks Brunk, I took the plunge. Seems the scope has a lot of support from enthusiastic users. The free spectrum analyzer software pushed me over the edge.

Yeah, its a really good unit for the money :) It's definitely serious enough to not be called a "toy" lol and should last many years. Mine should be arriving in less than a week now.

The pioneer vsx-406 and Yulong da8 for the HD800 sounds damn good biggrin.gif

Unless it is bringing in income, it's a toy...  I have one of these:

 

 

And it's still a toy...  But that doesn't mean I don't NEED it. :D:evil:

Hi Guys,

I got the itch a while ago to try speaker amps for headphones, since i have my he-6. 

I'm complete green to all electronics, so i had an xlr to speaker tap cable made, i crossed my fingers, closed my eyes and despite all the suggestions of being careful, use resistors and so on... i plugged the he-6 straight into my old Denon avr two days ago.

Man, I love the sound. I would never complain on my V200 not being great, just want to explore the opportunity of  trying my hd800 and t1 somehow on the same way. I also face the challenge of using these cans at the same time for family sessions - the famous volume level problem...

I'm reading this topic (just crossed page 14 and i plan to go through) but i was wondering, if anybody put something together for newbies like me explaining the basics or some suggestions where start with the learning.

I'm not planning to become engineer and i asked already around to have robrob's (u rock smily_headphones1.gif Robinettebox made (anybody in Italy or EU is interested to make it, shoot me a pm), but this road of using speaker amps raise a lot's of questions and concerns. Just want to be sure to choose the right path...

Happy Holidays to all of you

All 3 pair of your headphones are probably insensitive enough to not need attenuation and your solid state amp will happily drive a headphone impedance so you probably don't need any resistors in your interface. It sounds like you want an interface with 3 balanced XLR connections for those 'family sessions.'  Three 32 ohm headphones connected at the same time will give your amp about 11 ohms of effective speaker load so 3 cans at once isn't a problem. You can build a box with just wires, no resistors, which connects the speaker L+ to a 4 pin XLR pin 1, L- to pin 2, R+ to pin 3 and R- to pin 4. Then connect all three 4 pin XLR sockets pin 1 to pin1, 2 to 2, . . . That should do it for you.

I'd say for your family listening sessions, you are going to need to plan for independent volume adjustment for each channel.  Doesn't have to be a full range volume control, but you will need to adjust for the sensitivity of the various headphones.  The T1 and the HD800 are pretty sensitive cans compared to the HE-6!

Duh! That didn't even cross my mind! Even if all 3 headphones were close in sensitivity you'd still need individual volume controls--especially for the women ("Oh, that's too loud!"). :D

He's an engineer in the sense a janitor is a sanitation engineer?

Lmao.
post #2085 of 3116

Just want to let you guys know that I am loving my F5 + HE-6 during these winter nights! I want to share the joy, so I have a slot open for someone that would like a F5 amp. PM me for details. I also have a very nice integrated amp for sale that is ready to ship too :)
