Default Dantimax Volume Control an Aleph P1.7

http://electronics.dantimax.dk/Kits/index.html

Does anybody know if the Relay Volume Attentuator Boards from Dantimax will work properly with Aleph P1.7?
I'am using Kristians Aleph P1.7 PCB's in unbalanced mode and want to use a kind of ready solution for volume control (output).

The RelVol1 has a constant input impendance, the RelVol2 has only 26 steps. Have I only to change the
resistors in this circiut so that they match the Aleph's needs (2 oder 5 K) or is there something else I have to
consider due to the constant input impendance.

Regards
Arne

Hi,

you could use the volume board 1 with 64 steps and a 5k input impedance. A 5k pot also has a constant input impedance if you connect the output on the wiper (as in BOSOZ) so there should be no problem here. You will need 4 boards though if you want to keep it balanced or change the boards to work as a balanced output attenuator (shunt).

Why four boards? Do you need more than two channels? The boards are two-channel or balanced single-channel. I have a balanced version also, but I haven't tested it properly yet, so it isn't "released".

Best regards,

Hi Mikkel,

When would teh balanced version be available? Is it a constant impedance design?

One comment about your website. It would be nice to bundle recommended components together in a solution for one price.

There are lots of people who are going to build Kari's XBosoz boards very soon, and offering a quantity deal on a balanced version of a relay attuenator, relay input selector, controls, and LCD display.

Just my $.02 worth,

-David

I think it is ready - I just have to test it thoroughly to make sure the performance is as good as the standard type. It's the same circuit as the RelVol1, just using smaller relays (and twice as many).

It's just hard to figure out what to bundle. I'm not sure I have ever sold the same bundle twice yet

I think Illusus is planning a group buy.

Hi Mikkel,

Would the GB using your products for for Kari's xBosoz boards have a configuration as quoted above or using your current products?

Apart from the balanced version of the relay attenuator it doesn't differ from the standard products as far as I can see. I guess the groupbuy could include whatever people want - different combinations would be no problem.

Many of the parts for the different boards are the same, so even if many different boards were ordered I could still order the parts in large quantities.

Best regards,

Mikkel C. Simonsen

Sorry for the delay on the GB thread...I've been very busy. My plan is to start a wiki featuring all of the related kits from Mikkel, you pick and choose the kits you want. The discount should be proportionate to the amount of kits in demand, therefore, some things may not carry much of a discount at all, ie. if only one person wants a certain display. I may limit the choice of kits slightly... you know how hard it is to choose when there are too many items on the menu...less is easier on the chef as well.

The balanced attenuator kit would be ideal at this time. I am paralleling two RelVol1 boards to get balanced operation. I have everything assembled but am waiting on Kari and Anthony's group buys. Since I have all the necessary part/board dimensions I may build my case early and use Mikkel's kits in passive mode and add the BOSOZ when they arrive.

Hopefully I'll have some time this week to start the thread and wiki. I'm very curious about the amount of parties interested in purchasing the kits.

Hi Bartek,

Should we wait until Mikkel publishes his balanced version? I'd rather have a single balanced unit.

I know folks build single ended versions of the Bosoz, but most build balanced input and output.

I'm thinking that as well. The balanced att. will, likely, be a hot item due to Kari's GB.
