I'm so glad I was able to find a site to download my missing manuals. Very reasonable prices and they kept me informed about the process and I had my manual within less than a day. The only thing I wish was an option is a 100% English version with no spanish or anything. But overall great site.

The manual is complete with excellent quality! One suggestion, show number of pages and weather it is multi-lingual. The AD 600 Manuel is about 76 pages and over half is non English. This results in a larger print job than usually needed. Having this information, one could select the desired pages for printing.

This is an excellent handbook. We had no information on the appliance until we obtained this and are now able to use the appliance to its full potential. Strongly recommended.

8. Synthesis basics: Subtractive synthesis
As you can see the curve is flat in the low register (which means it neither amplifies nor dampens the frequencies in this part of the spectrum) and then, at a certain point, gradually starts falling. When applied to the wave above, this filter cuts away some of the high frequency material in the wave, like this:
Amplitude Amplitude

FILTER TYPES There are many types of filters, all with their different characteristics and purposes. We will here discuss the three most common types of filters: Lowpass filter The lowpass filter dampens high frequencies and lets low frequencies pass through unaffected, as in the example above. It is the most common synthesizer filter, since it can be used to �round off� the sharp sound of sawtooth waves and pulse waves.
Amplitude Fc (Cutoff Frequency)
Frequency
Highpass filter This is the opposite of the lowpass filter. It lets the high frequencies of the sound pass through and cuts off the low frequencies. This removes �bass� from a sound, without affecting the high end.
