Grounding this input causes 180 degrees of phase shift in the main received audio.
This phase shift may be required when using an external encryption device.
(rr) WIDE BAND GUARD RX AUDIO (Pin w)
This output is the single ended wide band guard audio output. It is capable of driving
a 2k Ohm impedance and has a 3 dB bandwidth of 1 Hz to 27.5 kHz. The output is
adjustable from .1 Vrms to 1.5 Vrms and set to .6 Vrms.
(ss) GD RX 180 ENABLE (Pin x)
Grounding this input causes 180 degrees of phase shift in the guard received audio.
This phase shift may be required when using an external encryption device.
(tt) GUARD RX AUDIO (Pin y)
This output is the single ended guard audio output. It is capable of driving a 2k Ohm
impedance and has a 3 dB bandwidth of 1 Hz to 3kHz. The output is adjustable from
.1 Vrms to 1.5 Vrms and set to .6 Vrms.
(uu) TX 180 ENABLE (Pin z)
Grounding this input causes 180 degrees of phase shift in the transmitted audio.
This phase shift may be required when using an external encryption device.
