[. . . ] External Infrared Receiver (Biamp #909-0030-00): The receiver consists of a black plastic box, which contains an infrared photo detector, an LED indicator, and three screw terminals. To install the receiver, first take off the front cover by removing the four screws. Mount the receiver to wall or other surface, using the two screw holes on the back cover (screws not included). The receiver should not be mounted in direct sunlight, or pointed directly at fluorescent lighting. For best results, there should be an unobstructed lineof-sight from transmitter to receiver. The receiver may be wired up to 2000 feet from the VSX41, using 2conductor shielded cable (not included). Route the cable through the access hole on the bottom of the receiver. The three screw terminals inside the receiver ("GND", "IR2", & "IR3") directly correspond to the Remote 1 and Remote 2 terminals on rear panel of the VSX41. Connect the cable shield to the "GND" terminal at each end. Use the two conductors to connect "IR2" to "IR2" and "IR3" to "IR3". When the VSX41 is turned on, power is delivered to the receiver. The LED indicator inside the receiver (and the IR LED indicator on the VSX41 front panel) will light whenever infrared information is detected. NOTE: The Infrared Receiver includes a "Remote Translator", which allows remote control via third-party controllers (instructions included with receiver). It can provide up to 40 buttons (12 more than standard remote controls), which are support by some ® other ADVANTAGE products. The VSX41 itself only supports 4 buttons (Channel Select), but it will also pass commands on to other Advantage products which have been connected to the Remote Output (see Applications on page 7). The Remote Interface Kit is a tested circuit board assembly, which includes two wiring harnesses. The circuit board connects to the VSX41 in exactly the same way the External Infrared Receiver does, using 2-conductor shielded cable (not included), and may be wired up to 2000 feet from the VSX41. The three screw terminals on the circuit board ("GND", "IR2", & "IR3") directly correspond to the Remote 1 & Remote 2 terminals on the rear panel of the VSX41. Connect the cable shield to the "GND" terminal at each end. Use the two conductors to connect "IR2" to "IR2" and "IR3" to "IR3". When the VSX41 is turned on, power is delivered to the circuit board. The circuit board is 2. 27"W by 2. 65"H, with four mounting holes (2" centers) and #6 mounting hardware provided. [. . . ] The 301 may be assigned so signal present in Channels 1 & 2 causes 15dB ducking of Channel 3 (example: mic priority over telephone). (When ® using the VSX41 as a "router", the Output connector is used as a single input. ) PRECEDENCE CMA60s provide power for the four ® paging zones. An ADVANTAGE DA28R receives input signal from a background music source, and distributes that signal to the Channel 2 input on the four CMA60s. The VSX41 provides four outputs, which are sent to the Channel 1 input on the four CMA60s. [. . . ]
