Remote control kits

Avocrow said:
Mikkel.. Thanks for the great kits--RelVol1 and VolControl1. I finished them today, and have a couple of questions:

I have the 50k resistor set. I have not installed the load resistors, R27 and R28, because my amp has 47.6k input impedance. While testing, I measured resistances of the 64 steps (input signal to output signal jumpers). The resistance generally drops as I turn the knob clockwise, but it has a number of skips--for example one skip is from 74.9k to 77.4 and then to 74.0, etc.

1) Is this because I have not installed the load resistors, and it will be resolved once I connect the board to the amplifier?

You can't measure the attenuation that way. There's both a series and a shunt part. So to measure the attenuation, you would have to conect a signal at the input and measure the output voltage with a 50k load.

2) Every time I power up the relay board and control board, the attenuation position is set to about 12 steps above max attenuation. Is this part of the design, or is it a result of the uninstalled resistors, or just an error?

That was done by design. The volume has to be at some level at power-up, so I chose -50dB as a reasonable default.

Best regards,

I have a little dedicated 5V power supply just to power my RelVol1C.

1. Is 100mA sufficient?

No, you will need 200mA when all the relays are on.

2. Can I send L1 to the 5V supply ground rather than the signal earth?

You can try. If it doesn't work, you will get some hum in the audio.

Best regards,

I am an happy owner of a control2 and 2 relvol3 boards, and i start thinking about an extension of my system, what are the options to add 4 new channels ?

If you want to control all eight channels together, you can connect the four RelVol3 boards to one control port of the Control2. If you connect the first two RelVol3 boards to port 1 and 2, and the last two to port 3, you can setup offsets between the channels.

I'm having a problem with goods odered and paid with mister Mikkel Simonsen: odered and paid 3 weeks ago, had a couple of short answers by email, and then no goods and no reply to my emails for 2 more weeks. If he areads this thread maybe he will at least decide to give a reply expalining his point about no reply and no goods after 3 weeks. Not a friendly customer service, to say the least!

Sorry about the bad customer service. Caused by too much work and delayed parts in this case. Your parts have been sent.

Best regards,

I must say I have never had any problems with Mikkel, Ok I admit sometimes he is "slow" but that is most likely due to work overload.....
However he has never missed out on anything in the end he has always provided a good service and reasonable prices.

I can only recommend Mikkel and Dantimax. I have been dealing with him for several years now.
 
Slow but sure, Mikkel is Trustworthy

Mikkel,
Thank you for shipping my order, I know that you had to wait for the specialized LCD. I believe this is why it took so long to receive my order after it was placed.

I ordered some parts on 10/16/08, I received my full order on 12/12/08. Just under 2 months.

I kept in touch with Mikkel via email, he ALWAYS returned my emails (some a few days later) but always kept me informed.

His kits are in (many) pieces and a true DIY kit. Great silk screening printing and quality of boards. Parts are listed in an itemized fashion. Documentation seems complete if somewhat sparse for a newbie like me. Not as easy to build as "Bas' " or "Broskie's" Aikido boards but very good for the parts count and complexity.

Overall ratings of Dantimax:
1 - 10 (10 is best)

Quality of parts: 10
Packaging and shipping: 10
Value to end user: 9
Timelyness of shipping: 3 (may be what I ordered)
Email and billing: 7-8
Help in choosing parts: 10 (I knew what I wanted but no clue how to do it) Thanks Mikkel 🙂
Quality of final build: Don't know yet, I haven't built either of 'em yet.

Would I do business with him again? Yes. No question.

I hope this helps someone who is looking for a kit to build and is (like I was) unsure of which vendor to buy from.

Thanks Mikkel,
Ron

Yes. Sometimes there are a couple of parts out of stock, and when somebody orders one of them, that will be the part that takes the longest to arrive - that seems to be the way it works at least...

They are not heathkit manuals - that's for sure. But writing manuals isn't easy, when you know all the "facts" already. I try to include everything I think is needed... But if some of you are missing some bits of information, just tell me about it, and I will try to add it.

Best regards,

Mikkel, this was not an attack on you or your manual writing skills, it was a commentary on my personal knowledge........As I stated. "Newbie"

Thanks for the offer of help, I'll ask if I need any.
