DCX2496 DAC volume control PCB

[bdipoala]

I have a few PCB's left over from a board run. The boards provide a 100 step digital volume control function for the DCX2496. The level can be adjusted using any universal IR remote control that supports Sony codes. Adjustments can also be made with a digital rotary control. All 6 channels of the DCX balanced outputs are adjusted simultaneously. The board has a few extra level controls for a sub woofer or whatever.

The board provides a 0 to 1.00V output to drive a digital panel meter to indicate the volume level.

The board also can provide an optical digital input that replaces the electrical type on the A input.

If you are not happy with behringer’s op-amp board, I have made a couple of replacement boards that are simpler single stage / signal channel. One board has balanced outputs using new XLR connectors and the other is unbalanced with consumer levels and RCA connectors. See attached picture with balanced outputs

The boards could also easily be used for any DAC project using an eval board or you own design.

I am asking $90 for the bare volume control PCB and $30 for the op-amp PCBs’.

If you would like me to send you better pictures, email me at bdipoala@aol.com

see attached picture showing the board inside the DCX chassis

This is a newer board design with more functions than the one I posted previously

I have been getting alot of questions on my vcontrol PCBs so I am posting the below description to help answer most of the questions. see attached.

I will contine to buy additional batches of PCB's as long as there is a demand for them.

still have any of the boards for sale???? Need a few, at the least.

I would be interested in boards, also.

I am looking for a PCB also, Bdipoala does not answer Email, is he still around?

[bdipoala]

I am still alive!

I have been getting requests for boards recently so I will be ordering a new batch.

I have attached a picture of the unbalanced output design.

How much are the boards?
Sorry,the price was highest up.

What kind of volume controller do you use?

I need three sets. That's a positive on that. ie, soonest.

Let me know soonest. Well..at least one set, for now. Need the output borad as well, which is why I say 'sets'.

And while I'm asking for the world, what in the world made you use digital pots? Are thes digitally controlled VCA's, or are they actual digital VCA's? Digital is yuck, which is the entire 'why' of upgrading a DCX to improve fidelity.

If they are digital VCA's, do you think it would take much to go to an analog unit? Too many d/a a/d d/a thingies going on in there for my taste. The one cycle of the behringer itself is bad enough. The result might be mud.

dang. now I have to buy Jan's board too. maybe scratch the output board and I'll buy Jan's unit, now that I remember it exists. Tthe behringer is now available again (which is why I'm even bothering), so I'm back on target again, due to behiringer's complete screw up that lasted nearly two years. idiots.
