ST-440 Four Place

|
|
| The ST-440 / ST-640 models are full stereo versions of the SAS-440 / SAS-640 auto squelch intercoms and include the remote music switcher ( RMS ) unit.
Pilot Isolate
Pilot isolate allows your passengers to listen to music or converse with each other while you talk to ATC without interruption. Even if the intercom is off, our fail safe feature allows the pilot to always hear and transmit on the radio.
Music Inputs
The ST-440 and ST-640 accept input from a CD player, cassette player, AM / FM stereo receiver or Walkman. Music is muted when the VHF / Comm is transmitting or receiving, or when speaking on the intercom. Passengers can also be put on uninterrupted music if they desire.
