The Intercom That Set The Standard
Sigtronics pioneered
the voice activated intercom market in 1974 and continues to deliver value and
performance today in the 4 or 6 place FAA TSO approved SPA-400 / 600 intercom
series. With fail safe features that allow pilots to always hear the radio even
if the intercom is off, and radio priority that assures ATC only hears the crew
member transmitting, the SPA intercom series is the standard by which all others
are judged.
Individual Mic Bias Allows The Use of Different Brands of Headsets
General aviation headset microphones draw power from the intercom or
radio mic line. Some poorly designed intercom systems hook all the headsets to
one mic line so that all the headsets must share the same power. Because
different headsets have different power requirements, one headset may draw just
enough power to work but there may not be enough power left over for any of the
other headsets to function. With this type of design two identical headsets will
work most of the time but get different types and models then you will have a
problem. The only way to fix this is to modify or replace the intercom system
with one that uses separate mic input lines. All Sigtronics intercom systems use
separate mic input lines and do not have this problem.
Compact Size
Choose either rectangular (horizontal or
vertical) or circular faceplate mounting configuration to fit anywhere in the
cockpit. With a compact 2.5" x 1" sized panel, the SPA system will easily fit in
the tightest panels. All installation hardware including jack kit and pre-wired
harness are included.
