Page 2: Introduction
4405 Introduction The 4405 is a seven output AES3 digital audio reframer and 2x1 switch. It is designed to operate as a 2x1 synchronous switch when locked to a AES11 or video reference. Facilities are provided to regenerate bitstreams to prevent invalid data from affecting downstream equipment. - Page 3 AES 3 Phase INPUT 1 Alignment Regenerator 7 AES3 Input error OUTPUTS Receiver Phase AES 3 Alignment INPUT 2 Regenerator Input error INPUT SELECT /TALLY OUT POWER DC POWER AND COSMOS STATUS STATUS DATA The 4405 digital audio reframer Technical Manual...

Page 4: Installation
4405 Installation The 4405 seven output digital audio reframer and 2x1 switch may be used in the 1050 3U and 1051 1U ICON modular product rackframes. It is used with either the K4405.3B 30mm rear panel for balanced digital audio I/O or the K4405.3U 30mm rear panel for unbalanced digital audio I/O. -

4405 Digital Audio Reframer Signal I/O The K4405.3U panel is equipped with BNC connectors for unbalanced digital audio, whilst the K4405.3B panel is equipped with a 25 way ‘D’ type connector. Both panels have a 15 way ‘D’ connector for control and in the case of K4405.3B, AES3 reference inputs. - Page 6 4405 Signal I/O (K4405.3B) K4405 Function Function O/P1- 0/P5- O/P1-+ 0/P5+ O/P2- O/P6- O/P2+ O/P6+ AES REF IN- AES REF IN+ O/P7- O/P3- O/P7+ O/P3+ O/P4- O/P4+ CONTROL + AES IN Control Pin outs Function Function SELECT 1 SELECT 2...

Page 8: Configuration
4405 Configuration The 4405 may be configured for different input termination options and to change regeneration and muting options during input error conditions. There is also a factory set-up adjustment for the re-clocking PLL, which should not require re-adjustment. Setting the input mode Use PL5 to change termination options for the AES or video reference and PL3 and PL4 to change termination options for module signal inputs. -

Page 10: Error Handling
4405 Error handling In its default mode this module will pass data transparently including the validity flag, unless an incoming error is detected, such as a crash switch, when it will repeat the last good sample in each channel. It will also set the validity flag to invalid if it detects that the relevant channel status flag indicates that the audio is not linear pcm. - Page 11 4405 Digital Audio Reframer Technical Manual...

Page 14: Trouble Shooting
Note: It is recommended to employ a common station video reference or a common AES11 reference for all digital audio equipment if accurate phasing to station signals is required throughout a facility. The 4405 should meet the timing requirements of AES11 under these conditions. - Page 15 Lights red when I/P 1 is not present or when channel 1 error flag (ERF) is set LOSS OF I/P 2 Lights red when I/P 2 is not present or when channel 2 error flag (ERF) is set POWER Lights green if all voltage rails present 4405 status indicator assignments Technical Manual...
