Purple Haze

From the February issue of EQ:


Fig 3. The purple waveform is compressed, while the magenta waveform is the original signal. Note how the uncompressed waveform has much higher peaks.

And yes, that is the original border at the top of the page... nothing screams compression like lavender in contrast to plum.

This week on We-Verb:

- We won't make you wait any longer: Our preamp is............ functional! (On the first try, might I add!) Scientific shootout between the SCA C84 and the...... Digi Mbox2. It will be nothing less than epic.

Happy New Year from We-Verb!



That's right! We celebrated New Years day the same way as the rest of you, with a glass of bubbly and a nice hot soldering iron to keep you warm. (Also, please ignore the monitors in the background, we are borrowing them to test them out... we will go into failure another time.)

We just wanted to give you a quick update, we have dove in to soldering components to the PCB on the C84 from Seventh Circle Audio.

First we had the painstaking task of sorting through the 150 or so electrical components and parts, matching them up to the Bill of Materials, just to make sure that everything was there. Clearly, the most fun was the tiny resistors, where their value is indicated from several colored bands that each stand for a number, and since the people who came up with this system were not art students, a lot of the colors look similar.

Luckily we have a digital multimeter, so we were able to verify the resistor values accurately. Also, for anyone else pursuing a project like this, once we found the value of the component, we put a piece of tape on it and wrote where it goes (e.g. R22, means resistor 22, which is silk-screened on the PCB):



We will post more as it happens! Since I'm sure you're dying to see it... yes, here is another gratuitous PCB shot:
