Thanks for the kind words Bartek!

I have made some more tests on the attenuator board now. It looks like the performance may be adequate for audio use

My test setup was this:
HP200CD oscillator (with floating transformer output) into the attenuator board. The balanced output from that went into a single op.amp. differential amp (I used a 5532) to convert the signal to unbalanced. The output level was measured with a HP 334A.

The frequency response is worst at no attenuation for some reason (-3dB at 490kHz). I got the same value at 3dB attenuation. At the other points I measured (6dB att. and down) the -1dB point was at 290kHz or higher (higher than 600kHz at some positions).

These measurements were made on a low(ish) impedance attenuator (10k total input impedance). If you use higher impedance resistors the frequency response will deteriorate (or the channel separation will, if you use the attenuator for four channels instead of two balanced channel).

Best regards,

Mikkel C. Simonsen

IMO-as long as the frequency response starts drooping above 100kHz it's a non issue.

I thought I posted a picture of my prototype board here, but it seems to have disappeared. It is available here, if anybody wan't to have a look.

Best regards,

Does that mean you can't access the webserver running on my home PC behind a firewall?

Here's an external link: picture

No, but you have to subtract the VAT yourself. The shop software was originally made for Denmark only, and I haven't had time to "fix" that yet.

No, most universal remotes should work. I have only had problems with some very cheap types (most of the cheap ones do work though).

No problem.

Hey Mikkel sorry to bother you so much but was going to ask if the items i am going to purchase of you are all in kit form (i gotta put it together myself) or are they pre built and tested?? This is what i am going to buy from you.....for now

Control2
C2Panel1-1
C2Panel1-2
C2Panel2
Input1
RelVol1
RelVol1RM
IRDet2
LCD24x2B

total ex V.A.T = 173.44 euros inc freight

total inc V.A.T = 214.64 euros inc freight

How can i change the price to ex V.A.T at the end of the order? I will be paying via B-Pay.

They are kits - unless you want to pay me for assembling them (and wait untill I have the time to do so...). If you have done some PCB soldering before, these should be no problem to assemble.

You can't change the price to ex VAT, but all that happens is that you will get an order confirmation email with the amount 214.64 - you just pay 173.44 instead.

I have never heard of BPay, but from the website it looks like something that's Australian only. So unless BPay makes a transfer to my account, you probably can't use them. The website mentions that I should contact my bank, if I want to accept BPay payments - the only problem is, that I haven't got a bank account in Australia...

Best regards,

Mikkel C. Simonsen
