DAC-END R (ES9018) full assembled board

[randytsuch]

How you have connected the Zapfilter 2 (DAC Balanced Voltage output or Balanced Current output) ?

I suggest to you eliminate the resitor I/V 80ohm and use as voltage.

I have it set up for balanced current, with bubbles 1,3,4,5,7 closed on zapfilter and the 4 jumpers installed on the dac end.

Looks like I need to change the bubbles to 2, 4, 6 on zapfilter and remove the 4 dacend jumpers for balanced voltage.
Does removing the jumpers take the I/V resistor out of the circuit?

I want to let it run it a little more, and spend some more time listening before I make changes, maybe I will try it this weekend.

I did a quick check of the jumpers, after thinking about it, it didn't seem right to add them for current out.

The jumper adds a 22 ohm resistor to ground, for each output (L-, L+, R-, R+).

Seems like I should remove jumper for I out?

hi!

if you need DAC run at V-out, you not use 4 jum. you see?

If need DAC run at I- Out, need use 4 jum!
thanks

Hello

Did You send my DAC ?

I sent rest of the money 10 days ago.

i see, i say some member need chassis and transformer i sent later,

dac of you i will sent next to day, thanks

I get to show you the complete DAC include:

1. the jacw input: BNC, RCA, Balance in, Balance out, TOSLINK, the wiring, labor costs for completion and installation of complete
2. 4 opam 2134
3. complete installation, you only use.
4. all price: $ 150

You need me, please pm me!

Thank you!

Any news about the shipping timing for people ordering the transformer?

Can anybody explain what this meant ?

This evening I have tested the following configurations with a my friend with lot of experience on audio reprodution and recording.

1) Actual op-amp module (balanced with passive IV 10ohm)
2) Satri design (balanced not suggested because it does not work good on balanced circuit)
3) Raleigh Audio Line Stage clone with K & K Audio Basic CCS modules (balanced current mode with passive IV 10ohm)
4) Un-balanced direct connection in voltage mode with only 2.2uF Z-Cap capacitor (0.1uF bypass MKP1837 as option)
5) Lundahl LL1684 (balanced in voltage mode with OS-CON)

The last is the best.

Any idea how well a LL1527 would work instead of the LL1684?

I don't doubt the 1684 is better, but I can get the 1527 for much less, and I have a limited budget.

Quanghao,

Wow!, and you still have time to organize and build a group buy! Congrats...

Hi guys, halo, congratulations you got the DAC and run it.

The remaining friends, including the DAC + power transformer ....

I need to do the following to ensure the transportation and the best for you.

I am alone, just the kids just do these things, but very hard but fun:

1. all mounting screws on the bottom
2. installed power transformers
3. mounting screws on the front

4. installation screen controller

5. DAC board assembly and packaging shell +

You see attached picture

Thank you all for your trust.


A dac running is a pleasure for me!

dac of you i will sent next to day, thanks

quanghao

Any idea when the chassis will be ready ? I'll sent my remaining payment once you confirm it.

BTW, do Vietnam Post provide tracking number. I don't mind to wait as long as it is traceable.

Thank you

Nevermind, I just ordered the 1684.

I want to say is: You will get complete product, you just enjoy the music. Please see pictures for better understanding!

Thank you!

Hi Quanghao:

And the total price for the assembled and tested DAC is?
Shipping time?
Guaranty time?

Thanks in advance for your answer.

Hello Qhanghao,
What are DC currents consumption on 9v supply and 15v-0-15v supply ?

what is mean,

If you need DC out +15 V - 0- -15V, need transformer have AC = 18-0-18

Here some info about currents consumption

Hi Quanghao:

And the total price for the assembled and tested DAC is?

Yes, the product is complete and thoroughly checked, then transfer to you

Shipping time?
You choose: fedexl: a week (not included in the product - your own payment)

Guaranty time?
One year

Thanks

Hello Quanghao,
I will wait to receive my kit to measure DC currents, because I'll put the power supply in an other chassis (three DACs in the same box !).
