TMA44 and TMA45 Audio Panels

Our TMA44 and TMA45 audio panels work seamlessly with Trig stack products, they combine practical features and great value. Both panels support IFR and VFR flight and will also operate with a wide selection of existing legacy avionics.

Trig audio panels enable simple control of all your navigation, communication and entertainment choices – benefiting from Trig’s ‘Better by Design’ philosophy. The result – a logical and high quality interface that’s easier to use, with features pilots and passengers really appreciate.

The great value panel that covers all the bases IFR/VFR

The TMA44 equips you for navigation and IFR flight, with switched inputs for; Nav 1, Nav 2, ADF, Aux and DME. An illuminated marker beacon for ILS approaches adds visual cues to marker audio tones. All switchgear has a positive feel, with adjustable panel illumination for a great user experience day or night.

The TMA44 has two additional unswitched inputs included for audio alerts, such as stall or undercarriage warnings. The option of playing music via two custom inputs is enhanced by the TMA44’s ‘smooth fade’ feature. This automatically adjusts music levels to ensure vital radio information is always clearly received.

Bluetooth and stereo – make every flight a sound performance

Hosting 2-6 seats the TMA45 has industry leading Trig Digital Noise Reduction (TDNR). By automatically selecting the optimum level of squelch and mic threshold TDNR reduces cockpit noise. This improves your audio environment; it aids pilot concentration and combats fatigue. Our Superior panel also features Trig Active Mute (TAM) this further removes unwanted background noise from radio static, producing class leading audio quality.
