1 ADX-102i/104i/108i AES/EBU Demultiplexer 1.1 Introduction

The ADX-102i/104i/108i is a very high-quality AES/EBU demultiplexer series. They are designed to extract up to eight 24-bit digital audio signal pairs from a single SMPTE 259M serial component digital video signal. The LTC output comes from the sampled LTC. A delay of up to 6 fields can be added to the audio and the time code to compensate for external system timing delays. The ADX-102i/104i/ 108i series has a built-in audio test generator as well as automatic 525/625 input detection. In addition, these modules supports full EDH monitoring. Audio groups are normally embedded into the HANC area of the 4:2:2 signal per SMPTE 272M. Miranda has expanded on this capability by permitting embedders to be cascaded and to also embed audio groups into time slots in the active picture area. The ADX-102i/104i/108i are members of the imaging family of digital video modules and therefore require the imaging Quartet-A-75, Quartet-A-110 or the imaging Symphonie frame with Symphonie-R-CX, Symphonie-R-A75, Symphonie-R-A110 or Symphonie-R-AX rear modules, for mounting and power.

1.2 Features

• Serial digital 4:2:2 input with active loop-through • Up to 8 AES/EBU outputs per module • Up to 48 cascaded AES/EBU outputs • Dolby E compatible • Up to 24-bit digital audio • LTC output • Left/Right channel swapping • Audio group selection • Audio output muting • Audio and TC selectable delay • Built-in audio test signal • EDH monitoring

2.4 ADX-102i/104i/108i Electrical Installation Refer to Figure 2.6 for rear panel electrical installation. 4:2:2 IN: serial digital video input with active loop-through

Connect a 4:2:2 serial digital video source to 4:2:2 IN. The ADX-102i/104i/108i accepts a 4:2:2 serial digital video signal in either 525 or 625-line format. This input must conform to the SMPTE 259M-C standard. Make sure the input 4:2:2 cable has a maximum length of 250 m (850'). Refer to section 3.3, Status Monitoring for a description of error and EDH status on the input signal. The 4:2:2 serial digital loop-through signals are provided by the BNC connector labeled 4:2:2 LOOP. This is an active loop through and does not require termination when not in use. Make sure that all serial digital video connections are point-to-point. For instance, there must be a point-to-point connection between the 4:2:2 IN BNC and the source equipment. If a T-connector is used to connect other equipment, the maximum specified cable length is no longer valid. AES OUT 1 to 4: digital audio outputs (Symphonie-R-CX, Symphonie-R-A75, or Quartet-A-75 rear panels) The AES OUT BNC connectors provide unbalanced digital audio signals extracted from the selected audio group of the 4:2:2 digital video source. These output signals conform to the AES-3id standard for 75Ω impedance signals. Set jumpers on card for 75Ω as described in section 2.5 Impedance Selection Jumpers. AES OUT: digital audio outputs (Symphonie-R-A110, Symphonie-R-AX and Quartet-A-110 rear panels) The AES signals, output on the AES OUT HD-26 connector, provide 110Ω balanced digital audio signals conforming to the AES3 standard. There are eight AES signals available. Figure 2.4 provides the pinout of the HD-26 rear panel connector. Set jumpers on card for 110Ω as described in section 2.5 Impedance Selection Jumpers.
