Description
The PM3000 is a 4- or 6-place (depending on model), panel-mounted inter-
com with multiple volume and VOX (voice activated squelch) circuits us-
ing unified volume and squelch controls for the pilot, copilot and passen-
gers.
With few controls for the pilot to use, the operation of the PM3000 is very
straightforward. Yet the unit outperforms its much more complicated com-
petition. Although there is only one volume control knob, when an adjust-
ment is made to the volume control, all output amplifiers are being changed
simultaneously. Likewise, when the squelch control knob is adjusted, sev-
eral VOX circuits are being changed at the same time. Since the system is
designed to use modern stereo headsets, it is not necessary to balance the
volume and squelch controls at the intercom.
The PM3000 has an automatic fail-safe interconnect to the aircraft radios.
If power is disrupted to the intercom for any reason, an internal relay will
connect the pilot's headset to the aircraft radio allowing continued radio
communications.
Provision for entertainment input allows the pilot, copilot and passengers
