Remote control kits

[mcs]

I have a bit of bad news... Some of the kit prices will go up on Monday.

The PCB prices and some of the parts prices have gone up, so I have to raise my prices on some kits a bit also. Nothing dramatic - 2-3€ in most cases, but if you were planning to order something, you may as well save a bit...

The following kits will go up in price:
C2Panel1-1, C2Panel1-2, C2Panel2, Phono1, RelVol1C/CM, VolControl1, VolControl2 and VolControl3.

The other kits will stay at the same price.

Best regards,

Hi, your kits look great.

Just so I understand, if I want a complete remote-control preamp with LCD, unbalanced inputs, rotary controls only and phono I will need:

1 ChipVol1
1 Control2
1 C2Panel2
1 LCD16x2BB
1 Input1
1 Phono1
1 15VAC transformer

Can the input selection be changed using the remote? Also, I'm not sure I understand what the VolControl3 board does. Can it replace the Control2/C2Panel2 combination?

Best,
Eric

Yes, almost. You will need either a dual-secondary transformer or two transformers. The second winding/transformer should be in the 6-15V range. One of the windings is for the op.amp. supply (+/-12V), and the other is for the +5V digital supply.

Can the input selection be changed using the remote?

Yes.

Also, I'm not sure I understand what the VolControl3 board does. Can it replace the Control2/C2Panel2 combination?

Yes, in a way it can. It's a more primitive version. You only have one rotary encoder on the VolControl3 (for the volume setting), and no input selection. The input selection is remote-only then. You also have no power switching and no per input volume offsets.

Hi Mikkel,

Your system looks great.

Please confirm my understanding of some units.
1. C2 Panel 1-2
This unit can be configured as:
(a) Rotary encoder - Volume
Rotary encoder - Input
Push-buttons - Tape Mon.,Power, Mute and Spare
(b) Rotary encoder - Volume
Push-buttons - Input (1-5), Tape Mon., Power, Mute and
Spare
(c) Push-buttons - Input (sequential), Volume (up/down),
Tape Mon., Power, Mute and Spare

Input, Volume, Power and Mute can be controlled by IR remote
in all three configurations.

2. Control 2
Since there are only three control ports in this unit. It is not enough
to control a fully balanced arrangement which consists of two
Input 1 and two Rel Vol 1M units.

Please also advise whether the Input labels on the LCD display can be
changed in late stage by user.

Sorry for a lot of questions, thanks in advance.

Not quite. You always need at least one rotary encoder (for volume) with the current software. The pushbuttons are always for power, mute and input 1-6 or input 1-5 and tape monitor.

The second encoder can be used as either an input selector or a balance control. If you don't want the buttons for input selection, you can just leave them out, and only fit the power, mute and tape monitor buttons for instance. If you don't want any buttons (except power), you can use the type 2 panel. And if you really want up/down buttons instead of an encoder, I can probably add that also

There are enough ports. In the standard setup each port is used for 2 channels. So in your system you would only need one port. You can use either an Input2 or two Input1 boards (control ports in parallel). The attenuator boards are connected to the input boards - also in parallel.

Please also advise whether the Input labels on the LCD display can be changed in late stage by user.

They can. You can use any characters from the standard HD44780 character set, as well as some Scandinavian oddities added by me...

Sorry for a lot of questions, thanks in advance.

No problem.

A bit of news (finally)

- I have finished the balanced relay attenuator
- I have added the input selector option for the RelVol2 that was discussed in a thread here loooong ago. Any interest in a balanced version of that also?

You can find both the new kits at the website.

Why not. Soon, you will have a few of us who are building Kari's X-CCS BOSOZ inquire about your remote control and attenuator. I would say that balanced attenuators and selectors will be high on the list.

[mcs]

There is a balanced input selector available already (Input2) - it's just the small 3-input add-on selector for RelVol2 that's only available in unbalanced. But perhaps I should make a balanced version also...

A small update.

I have added some knobs and enclosures to the website.

And now to something completely different...

I'm making a small number of ADAT receiver boards. They are meant for adding ADAT inputs to Apogee DA-12 DACs, but they can be used for other DACs (or DIY projects) also.

You can see the board here: http://stiftsbogtrykkeriet.dk/~mcs/ADAT-RX.jpg

Any interest?
