super V/I converter with LL 1684

Hello, I have doubts about super v / i converter with LL 1684 if it can equip my power amplifiers, there's only 2 volts at the end of the output. I have a Holton hpanvx 300 r2, and hpanvx 500 r1 in paralell in each cabinet, will super converter with LL 1684 be able to make enough output voltage for my amps.
I hope someone here can help me.

Parallel amps

I drive an amp and a subwoofer (class d amp inside most likely) in parallel from the output of my LL1684s. The amp is 100kohm input , however, I don't know what the input impediance of the subwoofer is. Using no preamp, direct out to transformers of a buffalo iiise.

[rredline]

Hi Quanghao,
Somehow I could not find Toslink connector for my DAC in my local store, can I get it from you? I can pay for it and you can ship it together with my discrete output stage later. Thanks.

 

[frankwilker]

Hi Quanghao,
i need also an output stage. I change my entry, number 24, thanks.

List of 30 members. I do not get more!
Thank you all!

Hi Quanghao,

I already own the first version of the DAC-END, it's great.
I am on the list for just the new output stage. Can you tell me what I need if I want to change to the LL1684 transformer output stage? Can I just buy the LL1684 transformer or do I need to make additional modifications?

You need to remove the output jump to convert in voltage mode and connect the LL1684, there is a pcb with connectors available from Quanghao

Thanks! I'll remove myself from the list in this thread and will instead add myself to the Super VI/ LL1684 list in the other thread.

Hi!

I will integrate this into an existing preamp chassis. It is possible to purchase just the silver buttons from you? I not, can someone tip me of where I can order suitable ones?

Best Regards Christian
