9er Systems

9er Systems is an aviation audio company in Knoxville, Tennessee. It makes adapters that connect aviation headsets to computers, and parts for real aircraft panels.

The company says its products are engineered, produced and supported in the USA. It designs and assembles them in Knoxville. The parts are made in Asheville, North Carolina, Ohio, Illinois and other places in the USA. The founders test and sign off every revision, and they assemble, test and pack each adapter themselves.

The simulator line connects an aviation headset to a PC, Mac or iPad. The USB2GA is the original product. It fits the twin plug headsets used in most general aviation cockpits. The USB2Lemo has the same mountable case but uses a 6-pin Lemo jack for headsets with panel power.

The adapters take power from the computer's USB port. This feeds the headset microphone, so no batteries or wall plugs are needed. The case comes with a sticky pad so users can mount it under a desk or on a yoke.

The aircraft line is called GA2DSub. It is a shielded circuit board with Switchcraft aviation jacks. It joins a general aviation dual plug to a DE-9 connector, with no hand soldering. It is made for aircraft mechanics, avionics shops and home builders.

9er Systems also offers a free companion app called USB2x Toolbar. It adds sidetone and voice activated VOX control to its adapters on Mac and Windows. The company tests with many general aviation headsets, both active noise reducing and passive. Its products are sold through its website and Amazon, and it supports resellers.
