Page 5: Description
DAC3000C02 is capable of converting any of these digital audio types into analog audio. The DAC3000C02 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
• Front panel indicators for invalid digital streams. • One UR3000 mounting frame can house up to 12 DAC3000C02 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. If PSU3300 or PSU3301 modules are used for this purpose then up to 12 modules can be installed. -

Page 11: Installation
ELECTROSTATIC DISCHARGE. Always use antistatic bags clearly identified with a high degree of shielding for storage and transportation. The DAC3000C02 module is composed of two parts: one DAC3000P03 main board and one DAC3000P02 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
3.4. Power considerations The UR3000 and UR3100 mounting frames can house as many DAC3000C02 modules as will fit in them. 3.5. Module configuration The DAC3000C02 module includes program jumpers that should be set before the unit is installed into a mounting frame. -
Page 13: Selection Of Coaxial Or Twisted Pair Cabling For The Digital Input
The DAC3000C02 uses the V bit of the AES/EBU stream to determine whether or not the digital signal contains audio: V=0 when the signal is audio and V=1 when it is not. -
Page 14: Selection Of De-Emphasis And Sampling Rate
DAC3000C02 3.5.4. Selection of de-emphasis and sampling rate The DAC3000C02 can perform a de-emphasis of 50/15 us. This is done during the digital filtering performed by the digital-to-analog converter and is therefore sensitive to the sampling rate. J1, J3, J8 and J12 select the de-emphasis for sampling rates of 32, 44.1 and 48 kHz. -

Albalá Ingenieros | Manual DAC3000C02 4. OPERATION This section describes the significance of the front panel indicators of the DAC3000C02 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 20: Functional Description
As long as the MUTE function is not activated the converter will output the digital information present in the corresponding AES/EBU stream. The DAC3000C02 does not output any signal for channels where the MUTE function is activated while: - The front panel LED is lit due to a failure in the signal. -
Page 21: Glossary
Albalá Ingenieros | Manual DAC3000C02 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 22 Albalá Ingenieros | Manual DAC3000C02 DAC3000C02...
