3. BLEND
High Blend is used for stations that are too remote or weak to permit
noise-free reception in stereo. In order to reduce noise and hiss, this
feature "blends" the stereo channels into mono within a narrow
audio frequency band, thereby reducing hiss considerably while still
maintaining good stereo separation. Pressing BLEND first shows the
status in the display panel. Pressing again within approx. five seconds
changes to ON or OFF.
4. IF
Intermediate Frequency control. Changes the IF between two values,
WIDE for the best possible sound quality and NARROW to remove
interference between stations that are very close to each other in
frequency. Pressing IF first shows the status in the display panel.
Pressing again within approx. five seconds changes to NARROW or
WIDE.
5. ANTENNA
Switches between one of the two antennas that may be connected
to the S400. Pressing ANTENNA first shows the status in the display
panel (Antenna 1 or 2). Pressing again within approx. five seconds
cycles between the two. Simultaneously, the signal strength for the
current antenna is shown as "S" and 0 to 9, where 0 is minimum or
no signal and 9 is maximum signal strength.
