OPERATING INSTRUCTIONS
Use of the Notch Filter
Occasionally, you may come across a sound that may be masking
or covering your ability to adequately hear any leaks. This may
be caused by nearby motors, fans, or many other annoyances.
(Unfortunately, the most common are sounds caused by
automobiles and traffic). The XLT-30 has a Notch, or reject feature,
that will assist in eliminating that sound from your frequency range.
Depress the NOTCH pad, and use the ARROW pads to move the
cursor to the point where the annoying sound is eliminated or at
its weakest. Depress the RESUME pad to set the Notch function.
(Hint: Depress the FILTER pad to go directly to the FILTER mode.
Now you can choose the type of Filter you wish to use AND still
have the annoying sound Notched).
