Remote control kits

Hi Mikkel,

First off I'm quite impressed with your presence and helpfulness here.

A few questions:

1) Remote1, SRU1010, motorpot and a 12vdc supply are all that's needed for the remote controlling of volume (just double checking, sorry if this is obvious!)

2) I want to use a panel mount IR receiver for this kit. Would something like this do the job, http://www.a1components.com/itemdisplayn.aspx?item=11766 , with specifications
- 3-conductor ribbon cable
- Accommodates GND, IR, VDC connections
- Infrared modulation frequency bandwidth: 34 - 40KHz

Finding a neat way to install an ir window is my biggest hurdle.. just drilling a hole won't do! Suggestions welcome... 😉

Thanks for your time.

You should connect the signal ground to the case. The signal ground is on the in/out headers of the RelVol3 boards.



Yes, pin 1 (XLR ground) should be connected at the in/out headers of the RelVol3 boards.

Hello,

I'am not sure of what to do, can you check the jointed drawing?

What did i do with the main safety earth ? Should i disconnected it or it must be connected to the case ?

Thanks a lot 😉

Can't say for sure. If the output is a 5V logic signal, then it should work.

How about using the glass/lens from an indicator light?

There are different options. What you have on the drawing should work, but connect the wires from the XLR connectors to only one ground pin of the RelVol3. You could also ground the XLR pin 1s to the case, and connect just one ground wire from the RelVol3 board to that ground point.

Unless everything is double isolated (class 2), you have to connect the safety earth to the case.

This Way ?

And for the load resistor part, my relvol3 is 10k an my amplifier is 20k so according to you manual, the load resistor should be 20K, but there is space for two load resistors by channel, does the two resistor should be 20k or the addition of the two pieces ?


Sorry for the beginner questions

Regards

Anthony

You have 2*10k resistors for your attenuator (20k total input impedance). Is the input impedance of your amp 20k from + to -? In that case, you need no load resistors. If it's 20k from + to ground and from - to ground (40k total), then you do need 2*20k load resistors per channel.

Is it reasonable to run about 25cm of wire from the RelVol1C to the front panel, to connect to the rotary encoder and IR module, or would it be advisable to use RelVol1 with the VolControl1 module for this distance?

Thanks again Mikkel, I've almost made up my mind 😀

If you you fit the decoupling RC at the IR detector (or use the IRDet2 board), 25cm of cable is no problem. But there's almost no difference in cost between RelVol1C/IRDet2 and RelVol1/VolControl1, so I think I would go for the latter.

Hi Mikkel, I just placed an order and wanted to ask what the procedure is to remove the VAT for non-EU orders? The order confirmation email I just received still has the EU/VAT price.

The procedure is to wait 🙂

I have just sent you a new order confirmation.

Or if you're in a hurry, just subtract 20% from everything but shipping.

Question

Hello Mikkel,

Did you ship the Philips remote handset that I ordered?

And, I accidentally input higher voltage into the ChipVol1 & VolControl3. The micon of the VolControl3 got very hot. After that accident it doesn't work. I think I burned the micon. Can you send me another micon? How much will it be?

And, do you think the ChipVol1 might be damaged by that accident? I checked voltages on several points said in the manual, and all were normal.

Please email me. You should know my email.

Regards,

Lee

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?

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?

I checked over my soldering and positions. Everything looks correct. I have not installed the IR sensor yet in VolControl1.

Many thanks!

Yes, I sent you both some days ago.

The PGA chip could be damaged. How high was the voltage?
