RT-1080 AM/FM Stereo Tuner

ANT ATT Button

Sometimes known as a LOCAL/DISTANCE
switch, the ANT ATT button reduces the sig-
nal level at the FM antenna input. For the best
reception of stations located some distance
away, this button should be in the default
or OFF position. However, if you are locat-
ed in an urban area very close to the radio
transmitter, the incoming signal may be high
enough to overload the FM inputs. Press this
button to reduce the incoming signal. When
activated, a LOC indicator appears in the dis-
play. Press the button again to toggle back
to normal operation. This switch only effects
FM reception.

FM IF NARROW Button

FM reception works by receiving and decoding
a carrier signal centered at the tuned frequen-
cy. To accommodate broadcast stations that
may be misadjusted off this carrier frequency,
the receiver accepts signals slightly to either
side of the tuned frequency. This generally
provides satisfactory performance.
If you are located in an urban area with a
large number of stations at closely spaced
frequencies, you may occasionally notice in-
terference from adjacent stations. To provide
better performance under these conditions,
the RT-1080 allows you to reduce the range
of frequencies to either side of the precise
tuned frequency, thus reducing inter-station
interference. Press the FM IF NARROW button
to use this feature. A NARROW indication will
appear in the display. Press the button again
to toggle back to normal operation.

ANT A/B Button

As described in the REAR PANEL CONNEC-
TIONS section of this manual, the RT-1080
provides two FM antenna connections, la-
beled A and B. This button toggles between
the two antenna inputs. An A or B indicator
will appear in the display, indicating which
FM antenna input is active.
