GMA 240 Audio Panel Entertainment Inputs The GMA 240 provides two stereo entertainment inputs; MUSIC 1 and MUSIC 2. A MUSIC 1/TEL jack is also located on the GMA 240 front panel. The MUSIC 1/TEL jack can accept music or telephone sources. The MUSIC 1 and MUSIC 2 rear inputs may be wired to either a stereo phone jack in a convenient place, or to an audio device in a fixed mount (e.g. a GPSMAP 396 dock or a CD player). These inputs are compatible with popular portable entertainment devices such as MP3 and CD players. The headphone outputs of these devices are plugged into the MUSIC 1 or MUSIC 2 jacks. Press the MUSIC Key to enable the selected music input to be heard. Press again to disable music audio. Press the MUSIC 1-2 Key to select either the MUSIC 1 or MUSIC 2 input. Annunciators above the key indicate which music source is selected. Either music source may be selected. The selected source is heard by all unless intercom isolation removes the audio. A music source plugged into the GMA 240 front panel MUSIC 1 jack will bypass the MUSIC 1 rear input. MUSIC is soft-muted under certain conditions. Soft-muting refers to the temporary reduction of music volume and a gradual return to its original level. This muting occurs during alerts (unless configured otherwise), during selected radio reception if the RADIO Key is selected, during intercom operation if the ICS Key is selected, and any time the TEL Key is selected. 10 Garmin GMA 240 Pilot's Guide 190-00917-00 Rev.
