GMA 350 Audio Panel

ENTERTAINMENT INPUTS

The GMA 350 provides three stereo telephone/entertainment inputs:

•The telephone/entertainment () Key controls a telephone or entertainment device connected to the rear of the audio panel or to the Front Panel Jack.

•The MUS1 and MUS2 Key controls the Entertainment Music audio input.

The Front Panel Jack can be used as an entertainment input or a telephone input (in which case, it operates simultaneously with the rear telephone interface). The Front Panel Jack is a 3.5-mm stereo jack that is compatible with popular portable entertainment devices such as MP3s, CD players, and cell phones. The headphone outputs of the entertainment devices are plugged into the Front Panel Jack.

Distribution of the entertainment inputs are configured in Blue-Select Mode.

TELEPHONE AND ENTERTAINMENT MUTING

Telephone and entertainment muting can be enabled or disabled by the user, however it is always muted during alerts.

Enabling/Disabling Muting

Press and hold the MUS1, MUS2, or () Key for two seconds to toggle muting on and off. The aural message “Mute Music on Reception Enabled/Disabled” or “Mute Tel and Jack on Reception Enabled/Disabled” is heard.

FAIL-SAFE OPERATION

If there is a failure of the GMA 350 or when power is not applied, a fail-safe circuit connects the pilot’s headset and microphone directly to the COM1 transceiver. Audio is not available on the speaker during Fail-safe operation.
