The EX-B-3 Infrared Base is a versatile and unique member of the Expandable Family ofAudex®
Infrared Emitter Systems. This base driver combines multiple inputs, controlled by a built-in mixer, with three output strings capable of providing both signal and power to repeaters located in the auditorium. This feature eliminates the need for AC power at the repeaters, often saving extensively on installation costs, and making placement of the emitters easier and more efficient.
With the addition of numerous features, the EX-B-3 continues to be a one-of-a-kind value in the ALD market. Output jacks are all XLR type. Wiring and installation is quicker and easier. The two balanced microphone inputs are also XLR type, and the expansion input and output utilizes F-Connectors. In addition to two mic and one line level inputs, a speaker level input using spring terminals, is available. This makes attachment to an existing sound system quick and easy - just take your pick - line level or speaker level! Gain trimmers used to balance the inputs are located on the front for ease of operation.
One of the most unique features is the ability to switch the unit from a stand-alone base to an expansion of another base. This feature is useful when the room being served is capable of being divided into two or more sections. By using one base per room division, each segment can be served by an independent base with its own set of emitters and input signal. When the segments are combined into one large room, the bases are switched to the expansion setting and function as slaves of the main base connected to the audio signal for the main room. This arrangement allows the infrared to be switched in the control room as easily as the sound system.
