Overview

Push button simplicity puts complete, flexible audio control right at your fingertips with Bendix/King’s easy-to-use KMA 24. It is self-contained, all solid-tate and stands only 1.3 nches high in your Silver Crown stack. The “slant top” package tailors it for the top slot in your instrument panel.

The KMA 24 controls as many as three transceivers and six receivers, including the internal marker beacon receiver and its
automatically dimmed 3-light presentation.

The KMA 24 provides transceiver and receiver outputs to speaker or headphones or both. A separate isolation
amplifier for headphones maintains constant, noise-free volume levels, even when several receivers are monitored at once. Keying a mike mutes all receivers automatically
to eliminate feedback.

Two rows of alternate-action push buttons on the KMA 24 console control all receiver audio distribution functions. It has a built-in, crystal controlled, superheterodyne marker beacon
receiver with a three-light display. The complete TSO’d 3-light marker beacon receiver built into the KMA 24 gives you an accurate visual and aural signal when you pass over a 75 MHz beacon.

The KMA 24 is offered in four configurations

Q&A

Q: Does the Silver Crown KMA 24 have intercom?

No, it does not. The older King audio panels require an external intercom. If you want an audio panel with a built in intercom, you'll want to see the newer Garmin line of audio panels.
