9.0 MODES IFB Mode This mode is used for one way 1 to 1 communication, e.g. director to talent. The talent will constantly listen to the IFB Aux signal or the AUX signal if the corresponding dip switch is in 'off' position (see point 8 internal controls / dip switches). The director can talk over the Aux signal by pushing and holding the IFB TALK button. The AUX volume will be dimmed to a set IFB dim factor and the microphone signal will be added to the IFB line.
10.0 CABLING For the PRO Series Intercom system the interconnecting cables are of the shielded two-conductor microphone cable type and the intercom line connectors are of the XLR-3 type. Audio and Call signals are on XLR pin 3, DC power is on XLR pin 2. XLR pin 1 is connected to the shield of the cable which functions as the common return for audio and power. Since the audio signal is transferred in an unbalanced * way, certain rules have to be obeyed when installing the cables of an intercom network.
11.0 PARTY LINE, TECHNICAL CONCEPT ASL's PRO Series offers a complete two way ('full duplex') communications system. Users of the system are connected via a 'party line'. Master stations (with built-in power supply), beltpacks, speaker stations and power supplies are interconnected via standard microphone cable. One wire is used as an audio line, one as a power line and the screen of the cable functions as earth/return. Current drive is used for signal transfer.
14.0 DESIGN CRITERIA Applications / Environment of use ASL Pro Series equipment is designed for use as a wired communications system in theatres, in Radio/TV production facilities, in factories, and in utilities com plexes such as airports, railway stations and coach terminals. ASL equipment can be used outdoors in normal weather conditions. In conditions with excessive cold (<-10° C), heat (>50° C) or humidity (>85%), ASL equipment might not perform properly.
