These threads cover some basic information for the previous version
Building Vicol Audio R2R Volume controller part 1
Building Vicol Audio R2R Volume controller part 2
Just don't be scared, for those who would like a an already built unit the pricing would be presented for the readily built ones.
Solutions based on R2R Volume control
This is for the previous version, I would believe we'll get more with the new one
Where to use
You can use this volume controller as a standalone controller in your amplifier
Or even build your pre-amplifier unit incorporating a buffer, should be built separately and this volume controller.
Features
Full details can be found on the official page Vicol Audio
Here is an extract:
Power supply
6V - 8V @ min. 10W
Front Panel Cut out
Available from Tvicol Audio
So this is considerably complicated device which includes BT volume control and soft start etc, plus the inputs. Might be really considered as a standalone until for implementation.
Tibia would help to answer the specific questions later on I think we can create a Q&A and build threads when some questions would arise and we will group them accordingly to allow Tibi to focus on the delivery rather than distracting him with the same question coming from different people
Market
If you go out to the market you can find a number of cheaper alternatives, like the potentiometers built on resistor ladder without realays starting at 30usd.
Or much more expensive models at several hundred and more without delivery.
An unsoldered kit of a like usually costs around 140 usd + delivery.Pricing for the built units is available below:
[book=Please note that I am just doing interest check to help Tibi to understand the demand. The payments would be submitted directly to Tibi's account once we have reached required number of requests]%[/book]
Pricing
If there would be enough interest the bare PCB option would also be available - pricing is TBC
When would we start
As Tibi already has the components he can start preparing the boards once the agreed number is reached.
Iti s up to diy members to decide at which price we would like to purchase the units.
Lets say we start this GB and let it last for half a year or until 50 or 100 units are sold.
In order to understand the bigger price that you are willing to pay and whether we should start GB request at 50 or wait for 100 requests, I have introduced a special column in the XLS spreadsheet Highest price

TBD with Tibi

Souds good. Lets see where we can get with ut. Tibi ia going to provide some photos later on to enjoy the project 🙂
if theres enough to get to the lower price I'd be interested.
Possibly balanced, I'm reassessing my system at the moment and might have made some changes by the time you get that much interest.

You can indicate your interst together with the price.
We will review the list when real GB is confirmed so would be nothing bad to join now and no penalty for leaving prior to real GB
I am wondering whether bare pcbs count against the GB price or only built pcbs.
Will need to add this to the description once we have answer. I am thinking about balanced version for myself as bare pcb with controller

ok I've added myself to the google doc with price.
If I require more than 5 input how would I achieve this?

My guess is you can use two imput boards, which would give you up to 10 inputs. Or use an additional input board from ebay with the number of additional inputs that you are looking for.
Your input selector should have enough capacity to accomodate the additional board.
Than you will need to decide whether you would like to have all the inputs routed to 1 output or two outputs. If the same output should be used an additional relay board might be neaded to switch in between the input boards themselves 🙂
BTW are you planning to use a single pair output or multi channel volume controller, I think the answer would depend based on it.
If it is multi channel output, than you can add up the relay and Volume controller boards as you wish 🙂
Lets ask Tibi when he gets back to us, how this query can be addressed in particular with this PCBs

Hello
I have just put my in the Google list. I want a ready built balanced version. Do I need to do anything further to take part in the group buy?
Best Regards

Hi All thank you for your interest. It looks like we are up for ten sets for now and more requests to go 🙂
This is a very interesting project. I would like to know if it can be bulit for a mix of balanced / unbalanced inputs.
So i am interested in a built balanced version.
Thank you very much,
Boris

You can mix balanced with unbalanced by using only one channel from a balanced unit.

Hi Tibi.
I was thinking about an uodate to balanced version later on
What would be the differencies between tge balanced and unbalanced build.
So far I can think of additional input boards. Would there be any difference in the volume control unit itself ?

You can start with a stereo and add later as many stereo/balanced channels you like.
