AAD2000C01

• AAD2000C03: Distributor with one input, three outputs and XLR connectors. Occupies

three slots of a mounting frame, does not have an input transformer and does not
permit access to the rear bus.

• AAD2000C04: Distributor with one input, three outputs and XLR connectors. Occupies

three slots of a mounting frame, includes an input transformer and does not permit
access to the rear bus.

It is possible to monitor the AAD2000C01 status remotely using a communications
controller module installed in the same mounting frame. In addition, certain controller
modules provide SNMP management and the ability to record events in a file including
date and time information for further analysis.

The AAD2000C01 is a TL2000 terminal line module and can be housed in a two rack unit
(2 RU) UR2000 mounting frame.

1.2. Features

• Analog audio signal distributor.

• Excellent intermodulation and wide dynamic range.

• Distributes one audio input to four outputs.

• Input is electronically balanced.

• Low impedance outputs can drive loads of up to 600Ω at maximum signal levels.

• Provides gain adjustment from -20 to 20dB via front panel potentiometer.

• Allows mixing signals between modules through an internal bus.

• Provides VU or Peak Program meters.

• Module control and supervision can be done remotely when the mounting frame is

equipped with a communications controller module.

• Low power.
