the new butler's are a new design (without balanced xlr inputs) so it would be a big undertaking to mod them. I think i am happy with my latest design though. It doesn't photograph all that well, but in person i like it. I'll take some pictures anyways.
as for the attenuator. the pot has no interaction with the actual audio path, it is just used in the digital domain to control the attenuator board remotely. The thing you are looking at will work but will limit you to having to go back to the amp or soundcard to attenuate the volume of the sub. The joshua tree; on the other hand, would allow you to remotely adjust the attenuation from your dash
I finally have everything that i need (componentwise) and they do look nice:
This is my first fully active system and i'm pretty excited!
now onto the install and tune
Hi Scott,really awesome setup,I also have the phaze and they are the best for my tastes!
Some questions :
-do you run the zapco with balanced input?How did you connect it?
Do you have the scheme of the symbilink cable and made an adapter?
-How do you run everything in active if the dac is only 2 channels?Do you have more than one dac?
thanks for the compliment, to answer your questions:
yes i will run the zapco with balanced inputs.
the phaze pin configuration is as follows:
Pin 1 = ground
Pin 2 = + phase
Pin 3 = - phase
the zapco symblink wire config is:
basically i just made a cable that has two xlr's connected to a symblink cable. not that hard to do
i have the pin out at home if you don't have a symblink cable to hack up.
as far as running everything active, i have a phaze ldx-23 active x-over. this is the layout (digital from the mobo to the dac, then balanced after that)
mobo > dac > attenuator > x-over > amps
That WILL sound good!
Fine combination of good parts AND a well thought through design (signal-wise).
Wouldn't it be an idea to control the attenuator with the PC? Just get an analog-out phidget/velleman board on USB and you're set. You could even combine with a potmeter so you can overrule the PC if needed...
What about an xtronic case for the pc? The design is different but could look nice next to the amps....maybe
So if i understand well,you basically connect xlr 1 to L+ and L- xlr 2 to R+andR- and where do you take the ground?shorting blue and green?
I don't think the xtronic case will fit the phaze.
What if you hide the lower part of the td1500,with the wood that cover from the middle of the amp,leaving the whole silver surface visible and with a design that isn't too much flat,but have the connectors and cables hidden.Then you can put the crossover completely shown,above this surface and between the 2 phaze,with the balanced cable that go under the wood,having some sort of central unit controlling them.You can then put some blue light inside the phaze and have some cool effect,you can even replace the light behind the tube.I think it will look nice.
Below the xover,you place the zapco with the cover in par in the wood,max 1-2 mm outside,that seem like a sign.
Xenia & Isabelle, totally in love!
