Garmin G1000 Audio Panel Pilot's Guide 190-00378-01 Rev. A INTRODUCTION 6A. 1 INTRODUCTION The G1000 audio panel, the GMA 1347, is a fully integrated audio panel with digital capability that is designed to enhance cockpit management by helping to reduce cockpit workload via a number of integrated navigation and communication channels. NOTE: This audio panel is intended to be used only as part of the G1000 Integrated Cockpit System. · The unit controls marker beacon receiver audio and features marker beacon audio muting. In addition, MASQTM (Master Avionics Squelch) processing helps to de-emphasize ambient noise from the avionics inputs, thereby improving cockpit communications. · The GMA 1347 is equipped with a digital clearance recorder with playback capability and up to 2. 5 minutes of recording. [. . . ] If the MKR/MUTE key is pressed while the marker beacon audio is muted, the marker audio becomes deactivated and the MKR/MUTE annunciator light is turned off. NOTE: The marker beacon receiver lights operate independently of the marker beacon audio and cannot be turned off. The marker beacon audio level is aligned at the factory to produce its rated audio output. Audio output level is also adjustable in Configuration mode. Please consult a Garmin-authorized service center for details. NOTE: The unit provides output for driving external marker beacon lamps and it provides a middle marker sense output for use with an autopilot. Marker Beacon Signal Augmentation The HI SENS key can be pressed to augment marker beacon signal reception sensitivity. The HI SENS function is typically used either over airway markers or to receive an earlier indication of a nearing outer marker during an approach. The middle marker sense indicator provides input to the autopilot. The lamp and audio keying of the marker beacon receiver are summarized in Table 6A. 3. 1. Figure 6A. 3. 3 Marker Beacon NOTE: The marker beacon signal sensitivity threshold can be set in Configuration mode. Please consult a Garmin-authorized service center for details. 190-00378-01 Rev.

A OPERATION AIRCRAFT RADIO INPUTS Pressing DME, ADF, AUX, NAV1, or NAV2 selects the corresponding audio source and activates the annunciator. Pressing the selected audio source key again deselects this audio source. Selected aircraft audio can be heard over the appropriate headset and over the speakers if SPKR is selected. Note that all aircraft radio keys can be selected concurrently. In Configuration mode, the DME, ADF and AUX radios may be disabled. Please consult a Garmin-authorized service center for details. MUSIC 1 As summarized in Table 6A. 3. 3, MUSIC 1 can be heard by the pilot in COPILOT mode and in ALL mode, and it can be heard by the copilot in PILOT mode and in ALL mode. MUSIC 1 Muting MUSIC 1 muting occurs upon aircraft radio activity, marker beacon activity, or ICS activity generated by the parties able to hear MUSIC 1. NOTE: MUSIC 1 muting during ICS activity can be disabled; please consult a Garmin-authorized service center for details. Figure 6A. 3. 5 Aircraft Radios Muting of this input is also triggered by marker beacon activity when in ALL, CREW, or COPILOT mode. After the activty that initiated the muting ceases, MUSIC 1 gradually returns to its original volume level at the headset outputs; this characteristic is know as "soft mute. " The time required for MUSIC 1 to return to its original volume level at the headset outputs is between 0. 5 and 4 seconds. NOTE: If the MKR/MUTE key is pressed and held for approximately three (3) seconds, the GMA 1347 toggles music muting during radio signal receptions ON and OFF. Upon toggling of this option, either one (1) beep or two (2) beeps can be heard; one (1) beep indicates that music muting is enabled and two (2) beeps indicate that music muting is disabled. When no further aircraft radio activity is detected by the unit, the amount of ambient background noise from the radios is further reduced by the Master Avionics Squelch (MASQTM) circuit. AUXILIARY ENTERTAINMENT INPUTS The current ICS isolation mode affects the distribution of the entertainment inputs MUSIC 1 and MUSIC 2. NOTE: MUSIC 1 and MUSIC 2 cannot be completely turned off. Audio level for these inputs can be set above and below a nominal value. Please consult a Garmin-authorized service center for details. 190-00378-01 Rev. A MUSIC 2 As summarized in Table 6A. 3. 3, MUSIC 2 can only be heard by the passengers and it is never muted. Garmin G1000 Audio Panel Pilot's Guide 11 OPERATION INTERCOM SYSTEM (ICS) ISOLATION The intercom system (ICS) provides four (4) isolation modes: ALL, PILOT, COPILOT, and CREW. The desired mode can be selected or deselected using the PILOT and COPLT keys. Figure 6A. 3. 6 ICS Isolation PILOT Mode PILOT mode is selected when only the PILOT key is annunciated. In PILOT mode, the pilot can hear the selected radios, the copilot can hear MUSIC 1, the passengers can hear MUSIC 2, and the copilot and passengers can communicate with each other. CREW Mode CREW mode is selected when both the PILOT and COPLT keys are annunciated. [. . . ] Anyone able to hear the selected COM radios is able to hear the COM signal playback. Once the 2. 5 minutes of recording time have been reached, the recorder begins recording over the stored memory blocks, starting from the oldest block. Powering off the unit automatically clears all recorded blocks. If a COM input signal is detected during playback, playback is halted and the new COM input signal is recorded as the latest block. NOTE: During playback, the PLAY annunciator light blinks approximately once per second. NOTE: The recorder can be disabled both using an external switch and in Configuration mode. [. . . ]
