ACCESS/A A711 L-Series Installation Manual 09RE416 REV. A 2.4.1 PASSENGER HEADSET CONSIDERATIONS The A711L has the ability to drive passenger ICS in both PTT or VOX modes, but you must consider this: Loose passenger headsets lying in the cabin MUST be properly accounted for. If the headsets are wired in directly, the loose headsets will be a continual source of intercom noise, rattling around the cabin.

A Figure 2-13 Full A711L Connector Map (view from mating connector wiring side) HEADPHONE INSTALLATION The A711L ACCESS/A Audio Controls are intended for use with industry standard 150/600 ohm headphones.

ACCESS/A A711 L-Series Installation Manual 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.). Shielded, twisted pair routing is strongly preferred for lowest noise pick-up, but single conductor shielded wiring generally gives adequate results in non-critical or single box installations, although noise floor and cross-talk will increase.

ACCESS/A A711 L-Series Installation Manual 09RE416 REV. A ANNUNCIATOR DIMMING 2.12 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).
