In the Control2 manual there is a function called Pin9 HW Mute, but to me it's not clear how to use it. http://www.diyaudio.com/forums/image...s/confused.gif
Is there anyboby who already has tried it?

Thanks,

I think I have sent you a reply by e-mail?

The HWMute function has nothing to do with this. You can connect an extra button for muting. The "Eject" button shown on the drawing will work as a mute button. The diode is a standard signal type like an 1N4148.

Im using mine in a slightly different way: I have all my RCA grounds tied together. The ground wire connects directly to the volume pot so no input ground connection passes through the Input1 module. I did this to try and avoid any potential ground loops and also to prevent any noise being injected onto the signal ground front the Input1.

Maybe I should wire it up in the standard way?

I measured the crosstalk some years ago, and it was very low (don't remember the numbers). But there will be some capacitive coupling through the relays. Is the sound you're hearing thin sounding (no bass)? It so, it is probably capacitive coupling. I have just tested my own preamp. I have to turn the volume all the way up to hear anything when I switch to a "neighbouring" input.

Looks like I haven't posted a new products update in a while... Here is a list of the latest additions.

TPower1: A small PCL86 PP tube poweramp. The output power is approx. 8W per channel in tetrode mode. The amp can be connected in UL and triode mode also.

TPre1: A tube preamp - phono stage and line stage included. This can be supplied either as parts for hardwiring or with PCBs (as usual ). Tubes used are 6N2P-EV in the input stage and 6N1P-EV in the following stages.

TCascode and TGain1: Boards that can be used for various tube stages. TCascode is for cascode stages obviously. TGain1 can be used for grounded cathode, cathode follower and plate follower circuits. The boards are designed for the standard ECC8x and 6NxP dual triodes. These boards are used for the preamp mentioned above.

BalDrv: A small board with a DRV134 and an XLR connector. Used for adding a balanced output to an unbalanced source.

Best regards,

Hi Mikkel.

From what you describe it does indeed seem to be capacitive coupling. I suppose taking the input ground via the Inut1 board isn't going to make any difference. This isn't a major issue, just a minor niggle.

I'll look into ways to overcome this if its possible.

Nice to hear from you.

Hardwired high voltage relays?

If you're sure your signal sources don't mind having their outputs shorted, you can replace the 100k resistors with wire links. That will shut them up... Many signal sources have 100-600R resistors in series with their outputs, so shorting the output is no problem. But there may be exceptions...

Thanks for that suggestion. I will look into it.

If you hear clicks on every step, it's usually caused by DC somewhere in the path. What's connected on the input and output? If you only have clicks at certain points (like -48/-47dB and -31/-32dB) I have a fix for that...

If using a RelVol1 or RelVol1C board only, you cannot get full muting. The attenuator cannot attenuate more than 63dB, so you get -63dB when you press the mute button. When you use an input selector also, there is a mute relay on that board.

DC in the path? Connected there are: my DAC (with trannies output, so no DC), a couple of CD reader, IPOD and so on, and the click is on every step.

Why didn't you state on your site that you controller can not full muting? Have you even seen a volume controller that can not reach volume zero?

Why dind't you reply to my mails? I have payed money for your volume control pal...

Hell yes there's DC. It powers the board!
Nothing in front of it but an Oppo BDP-83 and John Broskie's Aikido tube board after it.

Changed to High quality 100K resistors and now I don't get 0 volume either!
I'm with ya Piero7.......now where's my hammer???
