ACCESS/A A711 L-Series Installation Manual 1.6.1 09RE416 REV. A Power Limitations With Standard Set-up, which consists of six headsets connected, a power output of not less than 332 mW is delivered per headset (as represented by 150 ohms) provided that the Direct Alert Input is terminated in not less than 600 ohms and that nominal input voltages are applied at the applicable channel inputs. Nominal microphone input: 100 mVrms; Nominal Communications/Navigational Input: 5.5 Vrms. 1.6.
ACCESS/A A711 L-Series Installation Manual 1.6.4 09RE416 REV. A Isolation Limitations When in Pilot Isolation Mode, the pilot microphone for ICS operation is rendered inactive. Consequently, neither co-pilot nor passengers can receive pilot intercom transmissions while the latter is in Isolation mode. 1.6.5 Standard Settings Utilised Throughout Testing Pilot Headset Settings utilized throughout testing was for the standard 150 ohms impedance headset.

A Figure 2-13 Full A711L Connector Map (view from mating connector wiring side) 2.7 HEADPHONE INSTALLATION The A711L ACCESS/A Audio Controls are intended for use with industry standard 150/600 ohm headphones. There is also provision for connection to an 8 ohm (minimum impedance) speaker, for a supplemental cabin speaker output.
ACCESS/A A711 L-Series Installation Manual 2.8 09RE416 REV. A MICROPHONE INSTALLATION All microphone connections to the A711L must be done with shielded cables. The inputs are intended for use with standard “carbon-equivalent” or amplified dynamic Microphones (such as the D/C M1, M4 M7, etc.).
ACCESS/A A711 L-Series Installation Manual 2.12 09RE416 REV. A ANNUNCIATOR DIMMING The lighted annunciators (Radio Selected, TX status) can be operated in three ways. First, they can be run at their fixed intensity at all times, this is done by jumpering J102 Pin 6 (Day/Night Dim I/P) to J101 Pin 17 (28V Input Power). No connection is then made to J101 Pin 2 (Auto Dim Input).
