		Program Charts	5

25	Narrow Cut 4 (2.5kHz)	See note for programs 16-20 and 22-26



26	Narrow Cut 5 (8kHz)	See note for programs 16-20 and 22-26



27	High Shelf	Use this to eliminate the high end and leave everything else
		untouched (corner frequency is approximately 7kHz).



28	Sine Wave Pattern I	Mostly for show, but because Channel A & B are not linked,
		there can be some happy accidents in terms of how these
		programs affect your signals.



29	Sine Wave Pattern II	See note for program 28.

Note for programs 30-59

The following 30 programs reside in the User program area. They can be overwritten with your own programs. (Naturally, if you have done that, the following diagrams no longer apply.) We suggest that you try these before storing a new program in their place, though; you might find some of them useful as a starting point for some of your own programs. It is possible to recall all 30 of these at once (see page 71 for details). But be forewarned: doing so will erase any programs you have stored.
