Reviews
ordering was easy, delivery was prompt. all good.
This unit was ordered as a replacement for a old PS Engineering intercom that the crew side did not work well after years of good service. Only to Expedite the repair. PS Engineering has a very good return and repair program. Today our local Aircraft radio shops do not do bench work .
Great intercom, if you already have an audio panel. Wiring this unit is the Saturday project in the EAA SportAir Electricity Workshop (www.sportair.com). Have installed in several aircraft. Owners were all pleased.
Solved a long-standing radio problem.
Installed in a Piper Tomahawk works as advertised, crystal clear and the volume does not affect the radio volume they work independently. Very easy to install especially if you purchase the harness from Aircraft Spruce.
This review is of Aircraft Spruce and the order. The intercom has not been installed as of this review. Aircraft Spruce was very prompt with the order and getting the part in the mail. Arrived promptly from the Georgia East location and was packaged very well for safe handling. I recommend Aircraft Spruce for their promptness and pricing of the parts I have ordered so far. I will continue to look to Aircraft Spruce first for my needs.

Yes, per Dynon, they are compatible.
The harness will include all jacks for 4 positions within the aircraft and music input jacks. The ability of specifying the harness lengths versus standard length harnesses makes this part number custom.
Yes, this intercom is TSO approved.
Dimensions: 1.25" H x 2.60" W x 5.50" D. Weight 12 Ounces (0.342 kg).
Thank you for the information, we will post it for future customers.
It must be wired to an aircraft power source.
The Without-Crew model (PSE P/N 11922) has a center selector switch with a position labeled Iso* that allows the pilot to isolate himself and the radios from the other 3 intercom stations. While the With-Crew model (PSE P/N 11920) has a center selector switch with an additional third position labeled Crew which allows both the pilot and co-pilot positions (collectively the front seat flight crew) to isolate themselves from the back seater allowing the front seaters to converse with each other and transmit on the radios without the distraction or interruption from the back seaters. So it essentially comes down to whether the aircraft owner wants the pilot to be able to isolate himself alone or add the additional option of being able to isolate both front seaters as a Crew. Obviously there would be no reason to have the crew model in a two-seat aircraft. The jack wiring is also different between the two models so the harnesses are not the same.
The DB 25 connector is included with the unit and pins are crimp
