Peter is that going to be with the display also ?

Does it come with a remote ? or just a optical encoder ?

Default relay attenuators

I need to make a six channel attenuator because I tri-amp. How much for six relay boards and a controller board?

Each relay board is $10, controller board $20 (prices may change in a future).

Those are for PCBs only.The circuit works with encoder and remote. I described the circuit here: http://www.diyaudio.com/forums/showt...99#post1118699
Since the pics disapeared I'm posting them again here. I would appreciate any suggestions for suitable display units.

I'll take 6 relay boards and a controller board. How do you prefer to be paid?

All credits with regards to control board, display and programing go to Veteran.

The relay board design was our combined effort, the attenuator concept was my idea, however, I was heavily inspired by Placette Audio. We have incorporated few changes though, like completely different layout, use of printed board for relays and resistors mounting and adding additonal 3 steps to lower the control range by another 12db or so.

The steps are also more uniform and the actual value of attenuation is being displayed. Mute function is also included.

Paypal is fine, add $6 for shipping. My paypal address can be found here: http://www.audiosector.com/contact.asp

What about this one peter..

http://www.optrex.com/products/list....chTerm=C-51505

I have one if you want i can send it to you to test out.

Same ones that we used in teh Cdr pro2's.



P.s digikey sells them too.

Part # is C-51505 Optrex.

Each channel has its own dedicated board, with SMD realys mounted on both sides:

For this version I decided to use nude Vishays, you need 28 resistors to complete the task. The PCB also allows the use of Caddocks, which have slightly wider footprint. I gues that type of attenuator will also work well with regular type of resistors.

The resistors are mounted in two rows (series and shunt separately), the relays bypass them, depending on attenuation. I wanted to achieve the shortest signal path and it seems like it was the only elegant way to do it. This requires SMD relays though.
