stereo recording, use of a noise reduction system alone is
not enough. In this case, it is necessary to use the MPX fil-
ter.
What is the MPX filter?
FM stereo signals contain 19kHz pilot signals and 38kHz
subcarrier signals which convey the left and right channel in-
formation. These signals are necessary, but they must be
removed form the output signals of the tuner. If these signals
are not removed, they can affect the DOLBY NR system.
The MPx filter is designed to remove these pilot tone signals
from the recording.
When to use the MPX FILTER switch
Use this switch only when recording with the DOLBY NR
system. Most high quality tuners have filters to suppress FM
pilot tone signals. With these tuners, you can leave the MPX
FILTER switch OFF. With other tuners, the MPX FILTER
switch should be turned ON. The MPX FILTER switch
should also be turned on when you have monitored the just
recorded music and feel that the sound quality is not right.
