SPA-400N / SPA-600N Description
The SPA-400N (4 Place) and SPA-600N (6 Place) panel mount intercoms are specifically configured for very high noise
environments, such as Ultra-lights, Open Cockpit aircraft, and all Warbirds.
Features:
1. The SPA-400N / SPA-600N have circuitry that allows you to use either the voice activated intercom mode or a
push-to-intercom mode. In order to use 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.
2. Special High Noise circuitry
3. Stereo capability: If you want to have stereo/switching in the aircraft, order our ST-400N (4 Place) or ST-600N (6
Place) and our S-45S, S-58S or S-68S stereo headsets.
*If you have a Warbird (T-28, T-6, etc.) with the original military intercom, call Sigtronics regarding the best use of the
SPA-400N.
For the best communications in high noise aircraft, it is highly recommended that you use the Sigtronics’ high noise
proven M-80H mic, either on one of our headsets or incorporated into your helmet. Call us regarding upgrading your
helmet for the ultimate in communications.
SPA-4SN Description
The SPA-4SN 4 place panel mount intercom has the push-to-intercom feature and special high-noise circuitry. This
intercom has inputs for stereo music, all in one compact package.
Sport 200 / Sport 200S Description
The Sport 200 and Sport 200S are 2 place panel mount intercoms designed for Light-Sport, Ultralights and Rotary
Wing aircraft. They incorporate special high-noise circuitry and have the push-to-intercom feature that the SPA-400N
has. The Sport 200S is the stereo model.
SPO-22N / SPO-42N / SPO-62N Description
The SPO-22N (2 Place) / SPO-42N (4 Place) / SPO-62N (6 Place) portable intercoms are like the SPO-22 / SPO-42 /
SPO-62 in the brochure, however they incorporates special high-noise circuitry. They do not have the push-to-intercom
feature that the SPA-400N has. The SPO N intercoms work well in Ultralights and other high-noise environments, and
with hand held radios.
