TMA45 Superior
The TMA45 is our fully featured panel, perfect for aircraft owners who
don’t wish to compromise. If you are looking for great quality audio,
stereo music and mobile phone support via Bluetooth this panel
provides it all. Hosting 2-6 seats the TMA45 has all the functionality
of the TMA44 but adds 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.
By creating a more comfortable audio environment you are best
placed to enjoy the TMA45’s stereo music entertainment and mobile
phone connectivity. Integrated Bluetooth allows two portable
electronic devices to be connected providing stereo music and
communication options.
The TMA45 gives total flexibility to adjust audio inputs to best suit
your needs – it’s the preferred solution for discerning pilots who
want to stay connected.
TMA44 Standard
Easy Installation
The TMA44 suits aircraft owners looking for a great value panel
that covers aviation requirements. This mono panel supports 2-4
seats with independent control of crew and passenger audio. Two
additional unswitched inputs are 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.
The TMA44 deploys an industry standard 44 pin connector
allowing a simple retro-fit with older audio panels. The TMA45
has two connectors and is a plug and play retrofit for the GMA340.
Both units are designed to fit into a standard avionics rack.

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
