Features:
- The SPA-400N and SPA-600N have
circuitry that allows you to use
them either in the voice activated
intercom mode or in a push-to-intercom
mode. In order to use it in the
push-to-intercom mode, you will
need to install a separate PTT
switch for this purpose. This
feature is sometimes desirable
in open cockpit and ultra-light
aircraft where wind noise can
be a problem. Using a large windscreen
on the mic is very helpful, however.
- Special High Noise circuitry
- Stereo capability: If you want
to have stereo/switching in the
aircraft, order our ST-400N and
our S-45S or S58/68S headsets.
High Noise Environment Intercom Series SPA-400N & SPA-600N
The High Noise Environment Intercom
Series is designed specifically for
experimental, ultralights, warbirds,
helicopters and other high noise aircraft.
Push-to-intercom allows switch activation
as well as voice activation when desired.
Tested by Sigtronics at ambient noise
levels of between 115-120 decibels,
the SPA-400N and SPA-600N outperformed
all other intercoms on the market,
panel mounted as well as portable.
For the best communications in
high noise aircraft, it is highly
recommended that you use the Sigtronics
high noise proven M-80 mic, either
on one of our headsets or incorporated
into your helmet. Call us regarding
upgrading your helmet for the ultimate
in communications. |
