GB for R2R audio volume / input selection pcb

[iTiberius]

Would it be possible to use this board and setup one of the inputs (preferably balanced) with a home theater bypass? So for the volume control does not effect that input and it just pass's it through?
Is that possible with some modifications?

Yes, one bypass (direct) input is already included.
Schematic is available at :: vicol audio :: >> Products >> DanZup R-2R/shunt volume controller

Well thats perfect.. I'm in for a Balanced Set, so 2 relay and a control board. Will need the programed Atmel aswell...

 

[ultrachrome]

I'm interested in two stereo PCB sets with atmel microcontroller.

Below is a link to a google-doc with persons who registered to this group-buy till now.
There are few details which need to be cleared.
Persons who may like to have access and edit personally, are invited to send e-mail address to office@....ro (see my signature)

I had a look on the google-doc.
But there are some questions left:

• what are the advantages/disadvantages of shunt/r-2r version. Which is better? Where I can find information concerning the differences between the 2 principles?
  
• is the ATMEL programmed and can I use the same ATMEL/program and pcbs for LED and LCD?
  
• what is enclosed in one kit?
  
• were ther any estimated prices given?
  
• who I have to inform which kit number etc. I want to order?

I hope I haven´t missed the point while reading the thread.

But there are some questions left:


[*]what are the advantages/disadvantages of shunt/r-2r version. Which is better? Where I can find information concerning the differences between the 2 principles?

Here are two links which will explain you, in detail, all advantages/disadvantages of different resistor networks topologies.
Attenuator Kit Installation
Resistor-Switch Attenuator Networks for Audio Volume Control

[*]is the ATMEL programmed and can I use the same ATMEL/program and pcbs for LED and LCD?

Atmel is programmed to support LED or LCD, but not both in the same time, as there is no enough space on flash memory.

[*]what is enclosed in one kit?

PCB and all components.

[*]were ther any estimated prices given?

We are going for full kit only if 100 pcb's will be ordered.
Estimated price / pcb is 12 euro.
On other hand, will provide full BOM with links to Elementy i podzespo?y cz??ci elektroniczne - TME - Electronic Components , so you can just click and add to your shopping basket all the components. I think is more fair like this.

[*]who I have to inform which kit number etc. I want to order?

Just write here and me, jkraxi or Dan Zup will take care of your order.

What numbers will be required for this gb to go ahead?

 

[danzup]

What numbers will be required for this gb to go ahead?

At least 80 pieces of PCB to start the production , but better 100 of that for order......

Kit

How is the controller programmed?
Is it supplied by you pre-programmed?

COnfirming interest but worried about time to reach 100 PCB

Hi again,

I just want to confirm that I am still interested in balanced version, but I am really concerned about the time necessary to reach to 100 PCB.

Furthermore I don't understand the lack of interest in the volume control..might be missing something.

Cheers,

Max

Microcontroller will be supplied by us ready pre-programmed for RC5 or any other IR and shunt/R-2R operation.

Thank you for your confirmation.

Hi Tibi,

no problem. Could you give us an indication on how many PCB are ordered for now, maybe coupled with a group buy on the romanian forum ?

Just to have an idea on how long we'ill have to wait.

Cheers,

Max

 

[iTiberius]

Hi Max,

So far we have 18 PCB´s.

Tibi

 

[coolnose]

Total of preordered PCB?

Hi,

any update on the total until now ? Just to evaluate when we can expect to get this thing going for reeal.

Cheers,

Max

PCB's

If the controller is supplied with pcb's... I will go for a set!

 

[iTiberius]

We are going to put in production a small number of PCB´s.
All boards will come with controller ready programmed up to your needs.
Will let you know exact price after we get factory offer.

The BOM is already available on vicol-audio.ro and will be revised, so you can click and shop your needed components in order to complete the kit.

Tibi

Hi, tvicol

I am interested in these pcbs (depending on the price).
Is it correct that the r-2r version = ladder type?
If so, I would take a complete kit for r-2r-version for balanced stereo amp and an additional relay board for switching digital sources.

Marcel

Yes, it is a ladder type.

Ok. I would take a complete kit for r-2r-version for balanced stereo amp and an additional relay board for switching digital sources.
Whats about the price?
