Page 5: Description
The DAD3002C01 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
• Purely linear distributor amplifier. Output signal is a replica of the input signal. • Front panel indicator for input presence. • One UR3000 mounting frame can house up to 12 DAD3002C01 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 DAD3002C01 module is composed of two parts: one DAD3002P01 main board and one XAD3000P02 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
The attenuation for the loop-through input of the DAD3002C01 is 0.4 dB, equivalent to an amplitude loss of 5%. It is not recommended to cascade more than five modules with loop-through, although this number can be increased. -

Page 14: Interconnection
After these steps, the module is ready to be connected to other equipment. 3.7. Interconnection The following figure shows the DAD3002C01 module rear board connector layout. Rear view of the DAD3002C01 The DAD3002C01 module provides two analog audio inputs with loop-through (IN-A, IN-B) and six outputs (OUT1-A to OUT6-A, OUT1-B a OUT6-B) per section. -
Page 15: Digital Audio Connections
For digital audio connections 110 Ω characteristic impedance, two-wire shielded cable is preferred. The GND terminal allows connection of the cable shield. The DAD3002C01 can be used in installations with 75 Ω coax cabling instead of 110 Ω shielded twin-lead cabling. - Page 16 Albalá Ingenieros | Manual DAD3002C01 DAD3002C01...

Albalá Ingenieros | Manual DAD3002C01 4. OPERATION This section describes the significance of the front panel indicators of the DAD3002C01 module and their remote control and monitoring ability. 4.1. Front panel description The appearance of the front panel and the elements it contains are shown in the following illustration. -
Page 18: Functional Description
1.5 Vpp. 4.2. Functional description The DAD3002C01 distributor does not perform any manipulation of the digital stream - therefore the signal present at the output is a replica of the signal at the input. The distributor accepts AES/EBU digital audio signals with sampling rates between 16 kHz and 96 kHz. -
Page 19: Glossary
Albalá Ingenieros | Manual DAD3002C01 5. GLOSSARY AES/EBU This acronym covers the combined AES and EBU standard for transmission of digital audio. The standard defines a serial interface known as AES3 as per AES, EBU 3250-E as per EBU or ITU-R BS.647-2 as per ITU. The interface originally transmitted two channels (one pair) with PCM coding with a bit depth of 20 or 24 bit and a sampling frequency between 32 kHz and 192 kHz. - Page 20 Albalá Ingenieros | Manual DAD3002C01 DAD3002C01...
