9er Systems — An Aviation Audio Company

Our Products

Two product lines — simulator adapters for your desk, and PCB hardware for your panel.

Aviation headset → USB, for your PC / Mac / iPad simulator setup.

For standard GA twin plugs (PJ-068 / PJ-055)

The original 9er Systems adapter. Fits the dual-plug headsets used in the vast majority of general aviation cockpits.

For 6-pin Lemo panel-power plugs

Same mountable enclosure as USB2GA, with a 6-pin Lemo jack on the front. For headsets with the panel-powered 6-pin Lemo connector.

Real-aircraft installation hardware — for A&Ps, avionics shops, and DIY builders.

Aircraft PCB · GA dual-plug to DE-9 (DB-9)

Shielded PCB with Switchcraft aviation jacks and easy DE-9 termination — no hand-soldering required. Built for the real-aircraft side of the panel.

Designed, assembled, and supported in Knoxville, TN. Components manufactured in Asheville NC, Ohio, Illinois, and elsewhere in the USA.

Aviation headsets need power for their microphones. We supply it from your computer's USB port — no batteries, no wall warts.

Mountable enclosure with a sticky pad in the box. Mount under your desk or to your yoke and keep your wires under control.

We test against a wide variety of GA headsets — old and new, ANR and passive. Pete uses his Bose A20 and Lightspeed Delta Zulu with it daily.
