able, plus “NORM” (no filtering applied).
LOW CUT FILTER
NORM Select this position, when not using the “LOW CUT”
filter.
1 below 300 Hz (-6dB/Oct)
2 below 500 Hz (-6dB/Oct)
HIGH CUT FILTER
3 above 700 Hz (-6dB/Oct)
2 above 1k Hz (-6dB/Oct)

INPUT 1 / INPUT 2 Jack
These jacks accept input from two FT-2000 transceivers.
The front panel INPUT switch selects either jack 1 or
jack 2. When the connecting cable is inserted into the
EXT SPKR jack on the FT-2000 transceiver, the trans-
ceiver internal speaker will be muted.
This jack is gold plated, for outstanding audio performance.
LINE OUT Jack
This is an audio output jack that may be used for tape
recording or connection to other audio devices.
Audio output from this jack is conditioned by the settings
of the audio filters.
Audio output from this jack is also affected by the
transceiver's AF GAIN control(s), so you may adjust
the FT-2000 AF GAIN control for optimum output
level.
This jack is gold plated, for outstanding audio performance.
Audio Filter Operation
High-cut (2.4kHz, 1kHz, 700Hz) and Low-cut (500Hz, 300Hz) audio filters, with front-panel filter response selection.
The optimum filter setting will depend on the operating mode and band/noise conditions. For example:
PFor SSB operation
Setting the HIGH CUT filter to 2.4 kHz will cause audio
components above that frequency to be attenuated at a rate
of -6 dB per octave. This will reduce high-pitched noise,
and give the audio a more mellow sound.
FILTER
PFor CW operation
Setting LOW CUT to 500 Hz, and HIGH CUT to 700 Hz,
will create a bandpass filter with its peak at 600 Hz.

ENGLISH
PFor AM and FM operation
Begin operation in the “NORM” (Normal) position, cor-
responding to the widest fidelity available. If specific noise
or interference should arise, try engaging one or both of
the filters.
See the charts for typical response curves of these highly
useful filters. Often, reception and communications can
be significantly enhanced.
LOW CUT FILTER
NORM Select this position, when not using the “LOW CUT”
filter.
1 below 300 Hz (-6dB/Oct)
2 below 500 Hz (-6dB/Oct)
HIGH CUT FILTER
3 above 700 Hz (-6dB/Oct)
2 above 1k Hz (-6dB/Oct)
1 above 2.4k Hz (-6dB/Oct)
NORM Select this position, when not using the “HIGH CUT”
filter.
