  • Page 5: Description

    -4 to +12 dB. Each output also has its own amplifier circuitry, so that a short circuit at one output will not affect the others. The AAD3001C01 is a TL3000 terminal line module and can be housed in a three rack unit (3 RU) UR3000 mounting frame or a 1 RU UR3100 mounting frame.

  • Page 6: Features

    • Low impedance outputs can drive loads of up to 600 Ω at maximum signal levels. • One UR3000 mounting frame can house up to 12 AAD3001C01 modules. If power supply redundancy is required and FA3000 or FA3001 modules are used then only 10 modules can be housed in the mounting frame.

  • Page 11: Installation

    ELECTROSTATIC DISCHARGE. Always use antistatic bags clearly identified with a high degree of shielding for storage and transportation. The AAD3001C01 module is composed of two parts: one AAD3001P01 main board and one XAD3001P02 rear board. Both parts must be installed in a UR3000 or UR3100 mounting frame following the instructions in the corresponding section of this chapter.

  • Page 12: Environmental Considerations

    4 - Attach the rear board to the mounting frame with two M3 metric screws and tighten. 5 - Insert the AAD3001P01 board (main board of the AAD3001C01 module) into the front of the mounting frame. The edges of the card slide into two plastic guides inside the mounting frame.

    The following figure shows the AAD3001C01 module rear board connector layout. Rear view of the AAD3001C01 The AAD3001C01 module provides one analog audio input (IN-A) and six outputs (OUT1, OUT2, OUT3, OUT4, OUT5, OUT6). The rear interconnection board is not designed to withstand mechanical stress. The wiring must be fastened properly to the frame where the mounting frame is housed to prevent the rear board from supporting the weight of the cables.
  • Page 15 Albalá Ingenieros | Manual AAD3001C01 The analog audio outputs are balanced, low impedance and use 3.81 mm pitch terminal block connectors. For analog audio connections two-wire shielded cable is preferred. The GND terminal allows connection of the cable shield.
