Remote control kits

Mikkel:

In the above config, which board supports the remote mute, phase reverse, and tape loop? I think I may need another board. Also, will the instructions show me how to wire it so that these functions may be selected at the base?

Last question: With a TVA approach, the desire is to eliminate as much circuitry as possible to allow a pure signal to pass. As I understand it, with your boards the signal will only pass through a relay -- is this correct? Is your relay as good as a high quality switch such as an Elna or a Shalco?

Thanks

Mute works by selecting the ground tap on the transformer. The phase and tape loop relays are not on the board, but there is a header on the attenuator board for connecting them.

No, not at the base. The VolControl2 board only has the encoder for setting the volume. So the other functions can only be selected by the remote. If you need to change those setting on the front panel also, you can use the Control1 or 2.

It passes through two relays actually. That way the number of relays needed is halved. Whether you use relays or rotary switches the signal passes through gold-plated silver switches. I can't really see what difference it makes where the switches are placed...

Mikkel:

I'm not thrilled with the Control1 board. I think I will have more design flexibility with the Control2, so I'll go with that. So it controls both the RelVol2 and the VolControl2? Will the one PSU power all of that? Do I just add the Control2 to the order?

PS: I'm glad to hear about the high quality relay contacts!

No, if you use the Control2 you don't need the VolControl2. You need a display for the Control2 for setup (any LCD like a 1*16), but you don't need it for use if you don't want it.

Yes.

Do I just add the Control2 to the order?

Yes, and you should probably add a control panel type 1 also - since you wanted front panel controls for the mute/phase switching.

My kits arrived safe.



The boards are very good quality great value.:-) Highly recommended

Thanks for all your help.

Mikkel:

The LCD displays look too small to be seen across the room. Are there larger HD44780 displays available? I couldn't find any.

I assume that the VolControl2 display is large enough to view across the room. Could it be used with the Control2 just to get the encoder and display?

You can get bigger HD44780 LCDs but generally not much bigger. There are heaps on Ebay. VFD and PLED displays have more clarity and are viewable from wider angles but ofcourse they are more expensive and harder to find

You can find quite a few VFD's of larger size but they cost. I did find larger LCD's but I cannot find the url now I'm afraid, they were not much bigger though.

The blue display from Dantimax is a little hard to read at distance, for me it starts to become hard to read at 5ft plus.

A bar graph for volume would be cool, I can see the display fine just not make out the numbers clearly. It could switch back to numbers once you have finished adjusting. Maybe not possible though!

I think your best bet is to get a high contrast one, I've seen some red text on black background ones and they look much easier on the eye. All the geeks like me want blue, but infact it is not the clearest!

Matrix Orbital have a nice choice too : http://www.matrixorbital.com/index.p...character-lcds

Agree, the blue displays are hard to read...the red are better.

The best vould be an "analog" type, bar-graph, or just ~ 10 single diode-outputs to form a line, or the circle round the vol-knob...

Yes, you can get them much bigger. They cost a fortune though. I can check the prices for you. I have though about making a 1-line display using alphanumeric LED displays though. That wouldn't be cheap either, but it may be cheaper still.

I have made a small board with two displays for showing just the volume setting, if that's what you want.
